Changes

The first known Muslim to recognize this was the contradictions between the Bible and the Qur'anwas Ibn Khazem (?-1064 CE), [[vizier]] of [[Spain]] and writer against Christians. He concluded that because they were in disagreement, the Bible (containing the Torah, Zabur, and Injil) must be wrong. However, knowing that the Qur'an told Muhammad "believe in what hath been revealed to thee and what (scripture) was revealed before thee (the Torah and the Injil)." Qur'an Surah 4.162 He concluded, "Therefore, the present text must have been falsified by the Christians after the time of Muhammad."

Some scholars, such as Al Ghazzali (?-1111 CE), disagreed. [[Ibn Kathir]] (1301-1372) wrote that the Jews did not alter the Torah, only their interpretation of the Torah:

However, in the following two hundred years, most scholars came to agree with Ibn Khazem, but they pushed the date of change earlier, previous to the time of Muhammad. [[Paul]] and [[Constantine]] were often blamed. In more modern times, the belief of such conspiracy has been downplayed and replaced with the idea that corruption came through many small changes by many copyists in the second and third centuries CE for the Injil. The corruption of the Torah and Zabur was moved back to before the [[Common Era]]Jesus' time, before the earliest manuscripts known today. Today, the corruption of the holy books is a virtually undisputed belief.
