1)  Koran states that the Bible (scripture) is truth
Serah 5:
44  Lo! We did reveal the Torah, wherein is guidance and a light, by which the prophets who surrendered (unto Allah) judged the Jews, and the rabbis and the priests (judged) by such of Allah's Scripture as they were bidden to observe, and thereunto were they witnesses. So fear not mankind, but fear Me. And My revelations for a little gain. Whoso judgeth not by that which Allah hath revealed: such are disbelievers.
45  And We prescribed for them therein: The life for the life, and the eye for the eye, and the nose for the nose, and the ear for the ear, and the tooth for the tooth, and for wounds retaliation. But whoso forgoeth it (in the way of charity) it shall be expiation for him. Whoso judgeth not by that which Allah hath revealed: such are wrong-doers.
46  And We caused Jesus, son of Mary, to follow in their footsteps, confirming that which was (revealed) before him in the Torah, and We bestowed on him the Gospel wherein is guidance and a light, confirming that which was (revealed) before it in the Torah - a guidance and an admonition unto those who ward off (evil).
47  Let the People of the Gospel judge by that which Allah hath revealed therein. Whoso judgeth not by that which Allah hath revealed: such are evil-livers.
48  And unto thee have We revealed the Scripture with the truth, confirming whatever Scripture was before it, and a watcher over it. So judge between them by that which Allah hath revealed, and follow not their desires away from the truth which hath come unto thee. For each We have appointed a divine law and a traced-out way. Had Allah willed He could have made you one community. But that He may try you by that which He hath given you (He hath made you as ye are). So vie one with another in good works. Unto Allah ye will all return, and He will then inform you of that wherein ye differ.

68   “Say, O people of the Scripture! [Jews and Christians], you will be nothing unless you uphold the Torah and the Gospel, and all that is revealed to you from your Lord”

2)  Allah judges by deeds; Christ judges by repentance & faith:
Matthew 5:20   For I say to you, that unless your righteousness exceeds the righteousness of the scribes and Pharisees, you will by no means enter the kingdom of heaven.

Rom 3:20   Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.

Ephesians 2:8-9   For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, (9) not of works, lest anyone should boast.
Acts 3:19   Repent therefore and be converted, that your sins may be blotted out, so that times of refreshing may come from the presence of the Lord,

Romans 4:20-25   He(Abraham) did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God, (21) and being fully convinced that what He had promised He was also able to perform. (22) And therefore "it was accounted to him for righteousness." (23) Now it was not written for his sake alone that it was imputed to him, (24) but also for us. It shall be imputed to us who believe in Him who raised up Jesus our Lord from the dead, (25) who was delivered up because of our offenses, and was raised because of our justification.
Romans 9:30-33   What shall we say then? That Gentiles, who did not pursue righteousness, have attained to righteousness, even the righteousness of faith; (31) but Israel, pursuing the law of righteousness, has not attained to the law of righteousness. (32) Why? Because they did not seek it by faith, but as it were, by the works of the law. For they stumbled at that stumbling stone. (33) As it is written: "Behold, I lay in Zion a stumbling stone and rock of offense, And whoever believes on Him will not be put to shame."

Romans 10:1-4  Brethren, my heart's desire and prayer to God for Israel is that they may be saved. (2) For I bear them witness that they have a zeal for God, but not according to knowledge. (3) For they being ignorant of God's righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God. (4) For Christ is the end of the law for righteousness to everyone who believes.
Romans 10:9-13  that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. (10) For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. (11) For the Scripture says, "WHOEVER BELIEVES ON HIM WILL NOT BE PUT TO SHAME." (12) For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. (13) For "WHOEVER CALLS ON THE NAME OF THE LORD SHALL BE SAVED."

3)  Muslims worship a black stone at the Kaaba
Deuteronomy 5:8-9   ‘You shall not make for yourself a carved image any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; (9) you shall not bow down to them nor serve them. For I, the LORD your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me,
Exodus 20:23   You shall not make anything to be with Me - gods of silver or gods of gold you shall not make for yourselves.
Leviticus 26:1   'You shall not make idols for yourselves; neither a carved image nor a sacred pillar shall you rear up for yourselves; nor shall you set up an engraved stone in your land, to bow down to it; for I am the LORD your God.

4)  Jesus is God (Muslims believe Jesus was just a prophet)
John 1:1-3,14   In the beginning was the Word, and the Word was with God, and the Word was God. (2) He was in the beginning with God. (3) All things were made through Him, and without Him nothing was made that was made. (14) And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.

Colossians 1:15-20   He(Jesus) is the image of the invisible God, the firstborn over all creation. (16) For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. (17) And He is before all things, and in Him all things consist. (18) And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence. (19) For it pleased [the Father that] in Him all the fullness should dwell, (20) and by Him to reconcile all things to Himself, by Him, whether things on earth or things in heaven, having made peace through the blood of His cross.

Colossians 2:8-10   Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ. (9) For in Him dwells all the fullness of the Godhead bodily; (10) and you are complete in Him, who is the head of all principality and power.

1 John 2:21-23   I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth. (22) Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. (23) Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.

John 5:19-27  Then Jesus answered and said to them, "Most assuredly, I say to you, the Son can do nothing of Himself, but what He sees the Father do; for whatever He does, the Son also does in like manner. (20) For the Father loves the Son, and shows Him all things that He Himself does; and He will show Him greater works than these, that you may marvel. (21) For as the Father raises the dead and gives life to them, even so the Son gives life to whom He will. (22) For the Father judges no one, but has committed all judgment to the Son, (23) that all should honor the Son just as they honor the Father. He who does not honor the Son does not honor the Father who sent Him. (24) "Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life. (25) Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God; and those who hear will live. (26) For as the Father has life in Himself, so He has granted the Son to have life in Himself, (27) and has given Him authority to execute judgment also, because He is the Son of Man.

John 14:6   Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me".

John 10:23-39  And Jesus walked in the temple, in Solomon's porch. (24) Then the Jews surrounded Him and said to Him, "How long do You keep us in doubt? If You are the Christ, tell us plainly." (25) Jesus answered them, "I told you, and you do not believe. The works that I do in My Father's name, they bear witness of Me. (26) But you do not believe, because you are not of My sheep, as I said to you. (27) My sheep hear My voice, and I know them, and they follow Me. (28) And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. (29) My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father's hand. (30) I and My Father are one." (31) Then the Jews took up stones again to stone Him. (32) Jesus answered them, "Many good works I have shown you from My Father. For which of those works do you stone Me?" (33) The Jews answered Him, saying, "For a good work we do not stone You, but for blasphemy, and because You, being a Man, make Yourself God." (34) Jesus answered them, "Is it not written in your law, 'I SAID, "YOU ARE GODS" '? (35) If He called them gods, to whom the word of God came (and the Scripture cannot be broken), (36) do you say of Him whom the Father sanctified and sent into the world, 'You are blaspheming,' because I said, 'I am the Son of God'? (37) If I do not do the works of My Father, do not believe Me; (38) but if I do, though you do not believe Me, believe the works, that you may know and believe that the Father is in Me, and I in Him." (39) Therefore they sought again to seize Him, but He escaped out of their hand.

John 17:1-5  Jesus spoke these words, lifted up His eyes to heaven, and said: "Father, the hour has come. Glorify Your Son, that Your Son also may glorify You, (2) as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him. (3) And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent. (4) I have glorified You on the earth. I have finished the work which You have given Me to do. (5) And now, O Father, glorify Me together with Yourself, with the glory which I had with You before the world was.
Isaiah 42:8   I am the LORD, that is My name; And My glory I will not give to another, Nor My praise to carved images.
{If Jesus isn't God, then He would not have shared glory with the Father before the world began}
Matthew 25:31   "When the Son of Man comes in His glory, and all the holy angels with Him, then He will sit on the throne of His glory.

Luke 11:29-32  And while the crowds were thickly gathered together, He began to say, "This is an evil generation. It seeks a sign, and no sign will be given to it except the sign of Jonah the prophet. (30) For as Jonah became a sign to the Ninevites, so also the Son of Man will be to this generation. (31) The queen of the South will rise up in the judgment with the men of this generation and condemn them, for she came from the ends of the earth to hear the wisdom of Solomon; and indeed a greater than Solomon is here. (32) The men of Nineveh will rise up in the judgment with this generation and condemn it, for they repented at the preaching of Jonah; and indeed a greater than Jonah is here.
{Jesus here states that he is greater than a king and greater than a prophet}

Mark 14:61-62  But He kept silent and answered nothing. Again the high priest asked Him, saying to Him, "Are You the Christ, the Son of the Blessed?" (62) Jesus said, "I am. And you will see the Son of Man sitting at the right hand of the Power, and coming with the clouds of heaven."

Luke 22:70  Then they all said, "Are You then the Son of God?" So He(Jesus) said to them, "You rightly say that I am."

John 8:53-59   "Are You greater than our father Abraham, who is dead? And the prophets are dead. Whom do You make Yourself out to be?" (54) Jesus answered, "If I honor Myself, My honor is nothing. It is My Father who honors Me, of whom you say that He is your God. (55) "Yet you have not known Him, but I know Him. And if I say, 'I do not know Him,' I shall be a liar like you; but I do know Him and keep His word. (56) "Your father Abraham rejoiced to see My day, and he saw it and was glad." (57) Then the Jews said to Him, "You are not yet fifty years old, and have You seen Abraham?" (58) Jesus said to them, "Most assuredly, I say to you, before Abraham was, I AM." (59) Then they took up stones to throw at Him; but Jesus hid Himself and went out of the temple, going through the midst of them, and so passed by.
Exodus 3:13-14   Then Moses said to God, "Indeed, when I come to the children of Israel and say to them, 'The God of your fathers has sent me to you,' and they say to me, 'What is His name?' what shall I say to them?" (14) And God said to Moses, "I AM WHO I AM." And He said, "Thus you shall say to the children of Israel, 'I AM has sent me to you.'"
{Jesus refers to himself as  "I AM"}

Matthew 25:31-32   "When the Son of Man comes in His glory, and all the holy angels with Him, then He will sit on the throne of His glory. "All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats.
Ezekiel 34:17   'And as for you, O My flock, thus says the Lord GOD: "Behold, I shall judge between sheep and sheep, between rams and goats.
{Jesus & God judge between the sheep & the goats}  {Jesus & God referred to as a shepherd}

Hebrews 1:1-4   God, who at various times and in various ways spoke in time past to the fathers by the prophets, (2) has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds; (3) who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power, when He had by Himself purged our sins, sat down at the right hand of the Majesty on high, (4) having become so much better than the angels, as He has by inheritance obtained a more excellent name than they.
{These verses state that God in time past spoke through His prophets, but now speaks through His Son; thus very strongly implying that Jesus is, at the very least, more than just a prophet. Also, the surrounding context further verifies this by clearly showing that Jesus is in fact God.}
[See Hebrews 1:1-14]

5)  The covenant was with Isaac, not Ishmael
Genesis 17:18-22   And Abraham said to God, "Oh, that Ishmael might live before You!" (19) Then God said: "No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, and with his descendants after him. (20) "And as for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He shall beget twelve princes, and I will make him a great nation. (21) "But My covenant I will establish with Isaac, whom Sarah shall bear to you at this set time next year." (22) Then He finished talking with him, and God went up from Abraham.

Galatians 4:21-31   Tell me, you who desire to be under the law, do you not hear the law? (22) For it is written that Abraham had two sons: the one by a bondwoman, the other by a freewoman. (23) But he who was of the bondwoman was born according to the flesh, and he of the freewoman through promise, (24) which things are symbolic. For these are the two covenants: the one from Mount Sinai which gives birth to bondage, which is Hagar (25) for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children (26) but the Jerusalem above is free, which is the mother of us all.
(27) For it is written: "Rejoice, O barren, You who do not bear! Break forth and shout, You who are not in labor! For the desolate has many more children Than she who has a husband."
(28) Now we, brethren, as Isaac was, are children of promise. (29) But, as he who was born according to the flesh then persecuted him who was born according to the Spirit, even so it is now. (30) Nevertheless what does the Scripture say? "Cast out the bondwoman and her son, for the son of the bondwoman shall not be heir with the son of the freewoman." (31) So then, brethren, we are not children of the bondwoman but of the free.

6)  No polygamy
Gen 2:24   Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.
Mark 10:8   and the two shall become one flesh: so that they are no more two, but one flesh.

1 Corinthians 7:2   Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband.

1 Timothy 3:2   A bishop then must be blameless, the husband of one wife, temperate, sober-minded, of good behavior, hospitable, able to teach;
1 Timothy 3:12   Let deacons be the husbands of one wife, ruling their children and their own houses well.
Titus 1:5-6   For this reason I left you in Crete, that you should set in order the things that are lacking, and appoint elders in every city as I commanded you— (6) if a man is blameless, the husband of one wife, having faithful children not accused of dissipation or insubordination.

Matthew 19:3-9   The Pharisees also came to Him, testing Him, and saying to Him, "Is it lawful for a man to divorce his wife for just any reason?" (4) And He answered and said to them, "Have you not read that He who made them at the beginning 'MADE THEM MALE AND FEMALE,' (5) and said, 'FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH' ? (6) So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate." (7) They said to Him, "Why then did Moses command to give a certificate of divorce, and to put her away?" (8) He said to them, "Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so. (9) And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery."

Ephesians 5:17-33  Therefore do not be unwise, but understand what the will of the Lord is. (18) And do not be drunk with wine, in which is dissipation; but be filled with the Spirit, (19) speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord, (20) giving thanks always for all things to God the Father in the name of our Lord Jesus Christ, (21) submitting to one another in the fear of God. (22) Wives, submit to your own husbands, as to the Lord. (23) For the husband is head of the wife, as also Christ is head of the church; and He is the Savior of the body. (24) Therefore, just as the church is subject to Christ, so let the wives be to their own husbands in everything. (25) Husbands, love your wives, just as Christ also loved the church and gave Himself for her, (26) that He might sanctify and cleanse her with the washing of water by the word, (27) that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish. (28) So husbands ought to love their own wives as their own bodies; he who loves his wife loves himself. (29) For no one ever hated his own flesh, but nourishes and cherishes it, just as the Lord does the church. (30) For we are members of His body, of His flesh and of His bones. (31) "FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH." (32) This is a great mystery, but I speak concerning Christ and the church. (33) Nevertheless let each one of you in particular so love his own wife as himself, and let the wife see that she respects her husband.

Deuteronomy 17:17  Neither shall he multiply wives for himself, lest his heart turn away; nor shall he greatly multiply silver and gold for himself.

The difference that we have in the Bible is a difference between what is descriptive and what is prescriptive. So, what the Bible does is demonstrate the consequences that follow inextricably like night follows day when someone does something that is outside the will of the Lord. You certainly see that in the most graphic of terms with David’s son Solomon. You see that in the end, Solomon’s many wives and concubines turned his eyes away from the Lord. And so he died really in a miserable condition when you think about it. He was building pagan shrines and altars to pagan gods for his pagan wives. So the edict is clear, Deuteronomy 17:17, memorable because of its address, you must not multiply wives. If this was true for the kings, how much more was it true for the people, but polygamy was practiced in spite of God’s warnings, in spite of the prescriptions that you find in Scripture….

7)  Who goes to hell and why
Ecclesiastes 7:20   For there is not a just man on earth who does good And does not sin.
Psalms 14:2-3   The LORD looks down from heaven upon the children of men, To see if there are any who understand, who seek God. (3) They have all turned aside, They have together become corrupt; There is none who does good, No, not one.
Matthew 5:20   For I say to you, that unless your righteousness exceeds the righteousness of the scribes and Pharisees, you will by no means enter the kingdom of heaven.
James 2:10   For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all.
Galatians 3:10-12   For as many as are of the works of the law are under the curse; for it is written, "CURSED IS EVERYONE WHO DOES NOT CONTINUE IN ALL THINGS WHICH ARE WRITTEN IN THE BOOK OF THE LAW, TO DO THEM." (11) But that no one is justified by the law in the sight of God is evident, for "THE JUST SHALL LIVE BY FAITH." (12) Yet the law is not of faith, but "THE MAN WHO DOES THEM SHALL LIVE BY THEM."
Psalms 9:16-17   The LORD is known by the judgment He executes; The wicked is snared in the work of his own hands. Meditation. Selah (17) The wicked shall be turned into hell, And all the nations that forget God.
Isaiah 66:24   "And they shall go forth and look Upon the corpses of the men Who have transgressed against Me. For their worm does not die, And their fire is not quenched. They shall be an abhorrence to all flesh.
Psalms 5:4-5   For You are not a God who takes pleasure in wickedness, Nor shall evil dwell with You. (5) The boastful shall not stand in Your sight; You hate all workers of iniquity.
Habakkuk 1:12-13   Are You not from everlasting, O LORD my God, my Holy One? We shall not die. O LORD, You have appointed them for judgment; O Rock, You have marked them for correction. (13) You are of purer eyes than to behold evil, And cannot look on wickedness. Why do You look on those who deal treacherously, And hold Your tongue when the wicked devours A person more righteous than he?
2 Thessalonians 1:8-9   in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ. (9) These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power,
1 Peter 3:12   FOR THE EYES OF THE LORD ARE ON THE RIGHTEOUS, AND HIS EARS ARE OPEN TO THEIR PRAYERS; BUT THE FACE OF THE LORD IS AGAINST THOSE WHO DO EVIL."
Daniel 12:2   And many of those who sleep in the dust of the earth shall awake, Some to everlasting life, Some to shame and everlasting contempt.
John 3:16-18   For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. (17) For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. (18) "He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
John 14:6   Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me.
John 3:36   He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him."
Ephesians 2:8-9   For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, (9) not of works, lest anyone should boast.
Galatians 2:16   knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified.
Hebrews 10:26-31  For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, (27) but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. (28) Anyone who has rejected Moses' law dies without mercy on the testimony of two or three witnesses. (29) Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? (30) For we know Him who said, "VENGEANCE IS MINE, I WILL REPAY," says the Lord. And again, "THE LORD WILL JUDGE HIS PEOPLE." (31) It is a fearful thing to fall into the hands of the living God.

8)  God's grace is the only way to eternal life (heaven)
Ephesians 1:7   In Him (Jesus Christ) we have redemption through His blood, the forgiveness of sins, according to the riches of His grace
Hebrews 9:22   And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.
Hebrews 10:4   For it is impossible for the blood of bulls and goats to take away sins.
Hebrews 10:14   For by one offering He has perfected forever those who are being sanctified.
Hebrews 10:18   Now where there is remission of these, there is no longer an offering for sin.
Colossians 1:21-23   And you, who once were alienated and enemies in your mind by wicked works, yet now He has reconciled (22) in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight— (23) if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister.
Romans 3:23-26   for all have sinned and fall short of the glory of God, (24) being justified freely by His grace through the redemption that is in Christ Jesus, (25) whom God set forth as a propitiation by His blood, through faith, to demonstrate His righteousness, because in His forbearance God had passed over the sins that were previously committed, (26) to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus.
Acts 3:19   Repent therefore and be converted, that your sins may be blotted out, so that times of refreshing may come from the presence of the Lord,

Christ voluntarily gave His life for the sins of true believers -
John 10:14-18   I am the good shepherd; and I know My sheep, and am known by My own. (15) As the Father knows Me, even so I know the Father; and I lay down My life for the sheep. (16) And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd. (17) "Therefore My Father loves Me, because I lay down My life that I may take it again. (18) No one takes it from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again. This command I have received from My Father."

9)  Koran states that Christ was not crucified, but it was made to appear that way
Serah 4:157  And because of their saying: We slew the Messiah, Jesus son of Mary, Allah's messenger - they slew him not nor crucified him, but it appeared so unto them; and lo! those who disagree concerning it are in doubt thereof; they have no knowledge thereof save pursuit of a conjecture; they slew him not for certain.

The Bible states that Christ WAS crucified
Psalms 22:16   For dogs have surrounded Me; The congregation of the wicked has enclosed Me. They pierced My hands and My feet;
Zechariah 12:10   "And I will pour on the house of David and on the inhabitants of Jerusalem the Spirit of grace and supplication; then they will look on Me whom they pierced. Yes, they will mourn for Him as one mourns for his only son, and grieve for Him as one grieves for a firstborn.
Matthew 20:18-19   "Behold, we are going up to Jerusalem, and the Son of Man will be betrayed to the chief priests and to the scribes; and they will condemn Him to death, (19) and deliver Him to the Gentiles to mock and to scourge and to crucify. And the third day He will rise again."
Luke 23:33   And when they had come to the place called Calvary, there they crucified Him, and the criminals, one on the right hand and the other on the left.
John 20:26-29   And after eight days His disciples were again inside, and Thomas with them. Jesus came, the doors being shut, and stood in the midst, and said, "Peace to you!" (27) Then He said to Thomas, "Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing." (28) And Thomas answered and said to Him, "My Lord and my God!" (29) Jesus said to him, "Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed."
1 Corinthians 15:3-6   For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, (4) and that He was buried, and that He rose again the third day according to the Scriptures, (5) and that He was seen by Cephas, then by the twelve. (6) After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep.
1 Corinthians 15:12-14   Now if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? (13) But if there is no resurrection of the dead, then Christ is not risen. (14) And if Christ is not risen, then our preaching is empty and your faith is also empty.
1 Corinthians 15:17-21   And if Christ is not risen, your faith is futile; you are still in your sins! (18) Then also those who have fallen asleep in Christ have perished. (19) If in this life only we have hope in Christ, we are of all men the most pitiable. (20) But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep. (21) For since by man came death, by Man also came the resurrection of the dead.
{If the Koran is correct, then God is guilty of allowing millions of people to be deceived into believing in Christianity.}

Jesus prophecied His crucifixion:
Numbers 21:8   Then the LORD said to Moses, "Make a fiery serpent, and set it on a pole; and it shall be that everyone who is bitten, when he looks at it, shall live."
John 3:14-15   And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, (15) that whoever believes in Him should not perish but have eternal life.
John 12:32-33   And I, if I am lifted up from the earth, will draw all peoples to Myself." (33) This He said, signifying by what death He would die.
Matthew 20:18-19   "Behold, we are going up to Jerusalem, and the Son of Man will be betrayed to the chief priests and to the scribes; and they will condemn Him to death, (19) and deliver Him to the Gentiles to mock and to scourge and to crucify. And the third day He will rise again."

10)  Koran states that the Trinity is Father, Son & Mary (three gods)
Serah 4:171  O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not "Three" - Cease! (it is) better for you! - Allah is only One God. Far is it removed from His Transcendent Majesty that He should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.
Serah 5:116  And when Allah saith: O Jesus, son of Mary! Didst thou say unto mankind: Take me and my mother for two gods beside Allah ? he saith: Be glorified! It was not mine to utter that to which I had no right. If I used to say it, then Thou knewest it. Thou knowest what is in my mind, and I know not what is in Thy Mind. Lo! Thou, only Thou, art the Knower of Things Hidden ?

The Bible states that the Trinity is Father , Son & Holy Spirit (three persons but ONE God)
Isaiah 43:10   "You are My witnesses," says the LORD, "And My servant whom I have chosen, That you may know and believe Me, And understand that I am He. Before Me there was no God formed, Nor shall there be after Me.
Isaiah 44:6   "Thus says the LORD, the King of Israel, And his Redeemer, the LORD of hosts: 'I am the First and I am the Last; Besides Me there is no God.

Isaiah 48:12-16   "Listen to Me, O Jacob, And Israel, My called: I [am] He, I [am] the First, I [am] also the Last. (13) Indeed My hand has laid the foundation of the earth, And My right hand has stretched out the heavens; [When] I call to them, They stand up together. (14) "All of you, assemble yourselves, and hear! Who among them has declared these [things]? The LORD loves him; He shall do His pleasure on Babylon, And His arm [shall be against] the Chaldeans. (15) I, [even] I, have spoken; Yes, I have called him, I have brought him, and his way will prosper. (16) "Come near to Me, hear this: I have not spoken in secret from the beginning; From the time that it was, I [was] there. And now the Lord GOD and His Spirit Have sent Me."

Gen 1:26   And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
Isaiah 44:24   Thus says the LORD, your Redeemer, And He who formed you from the womb: "I [am] the LORD, who makes all [things], Who stretches out the heavens all alone, Who spreads abroad the earth by Myself;

Isaiah 9:6   For unto us a Child is born, Unto us a Son is given; And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.

Two persons of the Trinity are illustrated here:
The one who spoke to Moses face to face (Ex 33:11) and the one even Moses isn't allowed/able to see the face of (Ex 33:20).
Exodus 33:11   So the LORD spoke to Moses face to face, as a man speaks to his friend. And he would return to the camp, but his servant Joshua the son of Nun, a young man, did not depart from the tabernacle.
Exodus 33:20   But He said, "You cannot see My face; for no man shall see Me, and live."

John 17:5   "And now, O Father, glorify Me together with Yourself, with the glory which I had with You before the world was.
Isaiah 42:8   I am the LORD, that is My name; And My glory I will not give to another, Nor My praise to carved images.
{If Jesus isn't God, then He would not have shared glory with the Father before the world began}

1 John 2:23   Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
John 5:22-23   For the Father judges no one, but has committed all judgment to the Son, (23) that all should honor the Son just as they honor the Father. He who does not honor the Son does not honor the Father who sent Him.

Matthew 3:16-17   When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. (17) And suddenly a voice came from heaven, saying, "This is My beloved Son, in whom I am well pleased."
Mat 28:19   Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
{How could the Koran get the Trinity wrong if God was the author of it?}

11)  What Scripture says about violence
John 16:2-4  They will put you out of the synagogues; yes, the time is coming that whoever kills you will think that he offers God service. (3) And these things they will do to you because they have not known the Father nor Me. (4) But these things I have told you, that when the time comes, you may remember that I told you of them. "And these things I did not say to you at the beginning, because I was with you.
Matthew Henry's Commentary on John 16:1-4 -
Our Lord Jesus, by giving his disciples notice of trouble, designed that the terror might not be a surprise to them. It is possible for those who are real enemies to God's service, to pretend zeal for it. This does not lessen the sin of the persecutors; villanies will never be changed by putting the name of God to them.

Romans 12:14-21  Bless those who persecute you; bless and do not curse. (15) Rejoice with those who rejoice, and weep with those who weep. (16) Be of the same mind toward one another. Do not set your mind on high things, but associate with the humble. Do not be wise in your own opinion. (17) Repay no one evil for evil. Have regard for good things in the sight of all men. (18) If it is possible, as much as depends on you, live peaceably with all men. (19) Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, "VENGEANCE IS MINE, I WILL REPAY," says the Lord. (20) Therefore "IF YOUR ENEMY IS HUNGRY, FEED HIM; IF HE IS THIRSTY, GIVE HIM A DRINK; FOR IN SO DOING YOU WILL HEAP COALS OF FIRE ON HIS HEAD." (21) Do not be overcome by evil, but overcome evil with good.
Matthew Henry's commentary on Romans 12:17-21 -
Since men became enemies to God, they have been very ready to be enemies one to another. And those that embrace religion, must expect to meet with enemies in a world whose smiles seldom agree with Christ's. Recompense to no man evil for evil. That is a brutish recompence, befitting only animals, which are not conscious of any being above them, or of any existence hereafter. And not only do, but study and take care to do, that which is amiable and creditable, and recommends religion to all with whom you converse. Study the things that make for peace; if it be possible, without offending God and wounding conscience. Avenge not yourselves. This is a hard lesson to corrupt nature, therefore a remedy against it is added. Give place unto wrath. When a man's passion is up, and the stream is strong, let it pass off; lest it be made to rage the more against us. The line of our duty is clearly marked out, and if our enemies are not melted by persevering kindness, we are not to seek vengeance; they will be consumed by the fiery wrath of that God to whom vengeance belongeth. The last verse suggests what is not easily understood by the world; that in all strife and contention, those that revenge are conquered, and those that forgive are conquerors. Be not overcome of evil. Learn to defeat ill designs against you, either to change them, or to preserve your own peace. He that has this rule over his spirit, is better than the mighty. God's children may be asked whether it is not more sweet unto them than all earthly good, that God so enables them by his Spirit, thus to feel and act.

Verses from the Koran spoken of in the above video:

Chapter 5:43-45 -
(43) How come they unto thee for judgment when they have the Torah, wherein Allah hath delivered judgment (for them) ? Yet even after that they turn away. Such (folk) are not believers. (44) Lo! We did reveal the Torah, wherein is guidance and a light, by which the prophets who surrendered (unto Allah) judged the Jews, and the rabbis and the priests (judged) by such of Allah's Scripture as they were bidden to observe, and thereunto were they witnesses. So fear not mankind, but fear Me. And My revelations for a little gain. Whoso judgeth not by that which Allah hath revealed: such are disbelievers. (45) And We prescribed for them therein: The life for the life, and the eye for the eye, and the nose for the nose, and the ear for the ear, and the tooth for the tooth, and for wounds retaliation. But whoso forgoeth it (in the way of charity) it shall be expiation for him. Whoso judgeth not by that which Allah hath revealed: such are wrong-doers.

Chapter 5:46-47 -
(46) And We caused Jesus, son of Mary, to follow in their footsteps, confirming that which was (revealed) before him in the Torah, and We bestowed on him the Gospel wherein is guidance and a light, confirming that which was (revealed) before it in the Torah - a guidance and an admonition unto those who ward off (evil). (47) Let the People of the Gospel judge by that which Allah hath revealed therein. Whoso judgeth not by that which Allah hath revealed: such are evil-livers.

Chapter 3:55 -
(55) (And remember) when Allah said: O Jesus! Lo! I am gathering thee and causing thee to ascend unto Me, and am cleansing thee of those who disbelieve and am setting those who follow thee above those who disbelieve until the Day of Resurrection. Then unto Me ye will (all) return, and I shall judge between you as to that wherein ye used to differ.

Chapter 61:14 -
(14) O ye who believe! Be Allah's helpers, even as Jesus son of Mary said unto the disciples: Who are my helpers for Allah? They said: We are Allah's helpers. And a party of the Children of Israel believed, while a party disbelieved. Then We strengthened those who believed against their foe, and they became the uppermost.
