CLAIM : THIS IS A POPULAR LIE AMONG CHRISTIANS THAT QURAN DOESNOT SAY THAT BIBLE IS CORRUPTED,ACCORDING TO THEM INFACT QURAN SAYS BIBLE IS TRUE AND HIS WORDS CAN;T BE CHANGED !
Where the Quran says the Bible has been corrupted :
The Quran says that the current Torah, Psalms and Gospel (the New Testament) have been badly corrupted. Numerous passages of the Quran refer to man’s distortion and alterations of the previous books of revelations from Allah.
These passages in the Quran note that the received books by the People of the Book, The Jews and the Christians, do not conform to the original revelations that were given to Moses, David and Jesus.
Can ye (o ye men of Faith) entertain the hope that they will believe in you?- Seeing that a party of them heard the Word of Allah, and perverted it knowingly after they understood it… Then woe to those who write the Book with their own hands, and then say:”This is from Allah,” to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby. (Quran 2:75,79)
There is among them a section who distort the Book with their tongues: (As they read) you would think it is a part of the Book, but it is no part of the Book; and they say, “That is from Allah,” but it is not from Allah: It is they who tell a lie against Allah, and (well) they know it! (Quran 3:78)
But because of their breach of their covenant, We cursed them, and made their hearts grow hard; they change the words from their (right) places and forget a good part of the message that was sent them, nor wilt thou cease to find them- barring a few – ever bent on (new) deceits: but forgive them, and overlook (their misdeeds): for Allah loveth those who are kind.
From those, too, who call themselves Christians, We did take a covenant, but they forgot a good part of the message that was sent them: so we estranged them, with enmity and hatred between the one and the other, to the day of judgment. And soon will Allah show them what it is they have done. (Quran 5:13-14)
No just estimate of Allah do they make when they say: “Nothing doth Allah send down to man (by way of revelation)” Say: “Who then sent down the Book which Moses brought?- a light and guidance to man: But ye make it into (separate) sheets for show, while ye conceal much (of its contents): therein were ye taught that which ye knew not- neither ye nor your fathers.” Say: “Allah (sent it down)”: Then leave them to plunge in vain discourse and trifling. (Quran 6:91)
But those who wronged among them changed [the words] to a statement other than that which had been said to them. So We sent upon them a punishment from the sky for the wrong that they were doing. [Quran 7:162]
Among the Jews are those who distort words from their [proper] usages and say, “We hear and disobey” and “Hear but be not heard” and “Ra’ina,” twisting their tongues and defaming the religion. And if they had said [instead], “We hear and obey” and “Wait for us [to understand],” it would have been better for them and more suitable. But Allah has cursed them for their disbelief, so they believe not, except for a few.[Quran 4:46]
And [mention, O Muhammad], when Allah took a covenant from those who were given the Scripture, [saying], “You must make it clear to the people and not conceal it.” But they threw it away behind their backs and exchanged it for a small price. And wretched is that which they purchased. [Quran 3:187]
O People of the Scripture, there has come to you Our Messenger making clear to you much of what you used to conceal of the Scripture and overlooking much. There has come to you from Allah a light and a clear Book. [Quran 5:15]
Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture – those are cursed by Allah and cursed by those who curse. [Quran 2:159]
Indeed, they who conceal what Allah has sent down of the Book and exchange it for a small price – those consume not into their bellies except the Fire. And Allah will not speak to them on the Day of Resurrection, nor will He purify them. And they will have a painful punishment. [Quran 2:174]
Where Hadith Says Bible is corrupted :
The Hadith (sayings and actions of Prophet Muhammad in Islam) as well point out to Biblical Corruption. Consider these hadith:
Narrated Abu Huraira: The people of the Scripture (Jews) used to recite the Torah in Hebrew and they used to explain it in Arabic to the Muslims. On that Allah’s Apostle said, “Do not believe the people of the Scripture or disbelieve them, but say:– “We believe in Allah and what is revealed to us.” (2.136) (Bukhari Volume 6, Book 60, Number 12)
Narrated Ubaidullah: Ibn ‘Abbas said, “Why do you ask the people of the scripture about anything while your Book (Quran) which has been revealed to Allah’s Apostle is newer and the latest? You read it pure, undistorted and unchanged, and Allah has told you that the people of the scripture (Jews and Christians) changed their scripture and distorted it, and wrote the scripture with their own hands and said, ‘It is from Allah,’ to sell it for a little gain.
Does not the knowledge which has come to you prevent you from asking them about anything? No, by Allah, we have never seen any man from them asking you regarding what has been revealed to you!” (Bukhari Volume 9, Book 92, Number 461)
Narrated ‘Ubaidullah bin ‘Abdullah: ‘Abdullah bin ‘Abbas said, “O the group of Muslims! How can you ask the people of the Scriptures about anything while your Book which Allah has revealed to your Prophet contains the most recent news from Allah and is pure and not distorted?
Allah has told you that the people of the Scriptures have changed some of Allah’s Books and distorted it and wrote something with their own hands and said, ‘This is from Allah, so as to have a minor gain for it. Won’t the knowledge that has come to you stop you from asking them?
No, by Allah, we have never seen a man from them asking you about that (the Book Al-Qur’an ) which has been revealed to you. (Bukhari Volume 9, Book 93, Number 614)
What Scholars of Bible says :
The Gospels are not eyewitness accounts
-Allen D. Callahan, Associate Professor of New Testament, Harvard Divinity School
Some scholars say so many revisions occurred in the 100 years following Jesus’ death that no one can be absolutely sure of the accuracy or authenticity of the Gospels, especially of the words the authors attributed to Jesus himself.
-Jeffery L. Sheler, 
and WHAT MORE BIBLE ITSELF SPEAK ABOUT CORRUPTION :
” ‘How can you say, “We are wise, for we have the law of the LORD,” when actually the lying pen of the scribes has handled it falsely? (Jeremiah 8:8 New International Version)
Which Part of Bible is corrupted :
Any part which says: [my personal view]
GOD have Son.
God turned in to man.
God sent his son to die for us.
Salvation by Jesus Blood.
Every things which makes a human Equal to God.
Verse 4:136 of the Holy Quran:
“O you who have believed, believe in Allah and His Messenger and the Book that He sent down upon His Messenger and the Scripture which He sent down before. And whoever disbelieves in Allah, His angels, His books, His messengers, and the Last Day has certainly gone far astray.”
After this they may Ask ,if Bible is corrupted then Why Quran says “Ask People of Book” :
