What the Qur'an Says About the Bible - The Qur'an Never Says the Bible was Corrupted
The Qur'an says some people of the Book were hypocrites (Sura 5:61-63) and perverted what they heard. However, it never said that God's word, given to the people of the Book, was changed. God has the power to give His word, and God has the power to guard His word in safety from corruption.
Sura 2:75 says of some people (Jews of Medina?), "Hear the Word of Allah, and perverted it knowingly after they understood it." It does not say they corrupted the Bible, only that they perverted what they understood.
While the Qur'anic commentator Yusuf Ali tries to say the Biblical Gospel today is not the Injil (Gospel) meant in the Qur'an, the Qur'anic commentator Fazlur Rahman contradicts him. Jesus was taught the Gospel according to Sura 3:48, and Christians are the people of the Gospel in Sura 5:46. Finally, 'Aisha contradicts Yusuf Ali in Bukhari vol.4:605 and Sahih Muslim vol.1:301 p.98, where she tells that Khadija took Mohammed to a Christian convert who used to read the Gospels in Arabic.
