The Qur’an just so happens to tell us that the Bible (or, Judeo-Christian scriptures) were inspired by Allah. That is, they are revealed truth from Allah. Therefore we can see that without a doubt the Qur’an tells us that our Christian Scriptures have been revealed by Allah. Supposedly Allah cannot lie and the Qur’an cannot be in error, for if this could be so then we could stop our analysis right here since there would be no warrant to believe any of the suras reported truth. Having seen that the Qur’an claims that Allah has revealed himself in our Bible, let’s turn to our Bible and see what “Allah” says there. In Deuteronomy 13:1-5 “Allah” tells us that if future revelation contradicts previous revelation, then it has not come from God. Now then, does the Qur’an contradict previous revelation? If it does, then according to the Qur’an’s own terms it cannot be what it claims to be.

Let us now examine the Bible and the Qur’an. The Qur’an contradicts the Bible in many places. For example, we read In sura 28:9 that Moses is adopted by Pharaoh’s wife and not by his daughter as is reported in Exodus 2:10. In sura 4:157 we read that Jesus was not crucified, obviously contradicting all four Gospels. In sura 19:35 we read that God would not beget a son which contradict many passages in the Bible (e.g., John 3:16). Sura 11:42-46 tells us that Noah’s son drowned in the flood but Genesis 6: 7, 18 tells us that Noah’s wife and sons were saved. Abraham was the son of Azar according to the Qur’an in Sura 6:74 and the son of Terah in according to the Bible in Genesis 11:27. And in sura 19:28-35 we read that Marium, sister of Old Testament Aaron, is Jesus’ mother!

The Muslim can say that since the Qur’an is the ultimate authority then what it reports must be true and the previous revelation has been changed by the infidels (the Jews and Christians) who seek to undermine the final revelation from Allah. Put differently, the Muslim will claim that the Bible we have is not the Bible the Qur’an was talking about. We have a corrupted version of the Bible today. How should we respond to this out the Muslim surely will take?

First, we should note that while it is understandable that Christians would change (or add) passages reporting a crucifixion and Jesus being begotten by the Father, it is not clear why they would change some minor historical formalities such as who Abraham’s father was? or, why would the evil Christians and Jews change that Jacob pledged to serve Laben for 7 years in exchange for Rachel from what the Qur’an reports – that Moses served Jethro for Zipporah? These are most probably due to human error (remember Mohammad grew up in a largely verbal culture and probably only heard verbal accounts of the biblical stories. It is easy to see why he would mistake little details like these rather than it being intentional deceit on the part of Christian cover-up artists. On the other hand, though, our Muslim apologist friend can respond that if someone were smart enough then certainly they would even change minor details. Granted. So now we can only pile more evidences upon the Muslim.

An embarrassing sura for the Muslim is sura 10:94.. In this sura we read: “But if you are in doubt as to what We have revealed to you, ask those who read the Book before you; certainly the truth has come to you from your Lord, therefore you should not be of the disputers.”
