Let's end all these nonsense assertions that the Qur'an teaches the same God as in the Christians' Bible:
The Qur'an teaches that Jesus was no more than another prophet, and denies Jesus' divinity, crucifixion and resurrection - and it asserts the belief in Jesus is God - THE central teaching of Christianity, found across the New Testament, is blasphemy to Allah!
Per the Qur'an Surah passage references:
The Bible teaches Jesus IS God, is eternal, as if the Father and the Holy Spirit. The Qur'an denies this – saying Jesus was merely another prophet of Allah's – and thus was a created being:
Surah 2:136 We believe in Allah, and the revelation given to us, and to Abraham, Isma'il, Isaac, Jacob, and the Tribes, and that given to Moses and Jesus, and that given to (all) prophets from their Lord: We make no difference between one and another of them . . .
The Bible says Jesus was crucified and was Resurrected – but the Qur'an denies it:
Surah 4:157 That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";-but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not.
Again, the Qur'an says Jesus was not God, was only a messenger and denies the Trinity:
4:171 O People of the Book! Commit no excesses in your religion: Nor say of Allah aught but the truth. Christ Jesus the son of Mary was (no more than) a messenger of Allah, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so believe in Allah and His messengers. Say not "Trinity": desist: it will be better for you: for Allah is one Allah: Glory be to Him: (far exalted is He) above having a son. To Him belong all things in the heavens and on earth.
More contradiction: Allah (God) is not Christ!
Surah 5:17 In blasphemy indeed are those that say that Allah is Christ the son of Mary.
Jesus accepted worship as God, and claimed to be God (“I am”) - the Qur'an asserts belief Jesus was God to be blashphemy against Allah.
Surah 5:72 They do blaspheme who say: "Allah is Christ the son of Mary." But said Christ: "O Children of Israel! worship Allah, my Lord and your Lord." Whoever joins other gods with Allah,- Allah will forbid him the garden, and the Fire will be his abode.
More Qur'an assertions Jesus was ONLY a messenger, not God:
Surah 5:75 Christ the son of Mary was no more than a messenger; many were the messengers that passed away before him. His mother was a woman of truth. They had both to eat their (daily) food.
Qur'an hate-causing passages of the Qur'an against the Jews:
Surah 5:78 Curses were pronounced on those among the Children of Israel who rejected Faith, by the tongue of David and of Jesus the son of Mary: because they disobeyed and persisted in excesses.
A double Qur'an contradiction - as Jesus DID accept worship and claim to be God, and He never asserted such about His mother Mary:
5:116 Allah will say: "O Jesus the son of Mary! Didst thou say unto men, worship me and my mother as gods in derogation of Allah'?" He will say: "Glory to Thee! never could I say what I had no right (to say). Had I said such a thing, thou wouldst indeed have known it. Thou knowest what is in my heart . . ."
Another Qur'an contrast to show that those following Allah believe differently than Christians do, about God – and its contempt that “Christians call Christ the son of Allah (of God):
Surah 9:30 The Jews call 'Uzair a son of Allah, and the Christians call Christ the son of Allah.
Surah 9:31 They take their priests and their anchorites to be their lords in derogation of Allah, and (they take as their Lord) Christ the son of Mary; yet they were commanded to worship but One Allah: there is no god but He. Praise and glory to Him: (Far is He) from having the partners they associate (with Him).
Jesus claim to be God is denied in the Qur'an:
Surah 19:19 He said: "Nay, I am only a messenger from thy Lord, (to announce) to thee the gift of a holy son."
The Qur'an on Jesus Himself states He is only a prophet:
Surah 19:30 He said: "I am indeed a servant of Allah: He hath given me revelation and made me a prophet."
Qur'an sarcasm per the belief of Christians, per Scripture:
Surah 19:88 They say: "(Allah) Most Gracious has begotten a son!"
Surah 19:91 That they should invoke a son for (Allah) Most Gracious.
19:92 For it is not consonant with the majesty of (Allah) Most Gracious that He should beget a son.
The Qur'an asserts Jesus said He was only a messenger and pointed to another one after Him – both contradictions of Scripture – in fact, Jesus said the entirety of the Old Testament pointed to Him, and the New Testament ends with NO future prophet as asserted, and only in looking forward to Jesus' future return:
Surah 61:6 And remember, Jesus, the son of Mary, said: "O Children of Israel! I am the messenger of Allah (sent) to you, confirming the Law (which came) before me, and giving Glad Tidings of a Messenger to come after me, whose name shall be Ahmad." But when he came to them with Clear Signs, they said, "this is evident sorcery!"
Per various popular translations of the Qur'an, a denial of Jesus' Crucifixion and Resurrection:
Haleem—[Jews] said, ‘We have killed the Messiah, Jesus, son of Mary, the Messenger of God.’ (They did not kill him, nor did they crucify him, though it was made to appear like that to them; those that disagreed about him are full of doubt, with no knowledge to follow, only supposition: they certainly did not kill him.)
Sahih International—And for their saying, ‘Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah.’ And they did not kill him, nor did they crucify him; but another was made to resemble him to them. And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him, for certain.
Yusuf Ali—That they said (in boast), ‘We killed Christ Jesus the son of Mary, the Messenger of Allah’; – but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not.
