I’m no expert on Islam, so please correct anything in this post that is untrue.
First off, correct me if I’m wrong, but a central tenet of Muslim belief is that the Bible (Old and New Testament) has become corrupted, and that God sent Mohammad as the final prophet to preach the true divine message–Islam. The earlier prophets (Moses, Jesus, etc) were true prophets, but their words have become corrupted, leading to the doctrines that are unique to Christianity, that Muslims don’t believe in (Divinity of Christ, Trinity, death and resurrection of Christ, etc.) There are also contradictions between the Old Testament and the Koran (Abraham almost sacrificing Isaac in the Bible, Ishmael in the Koran), and as I understand it, Muslims would also say that these are areas where the Scriptures have become corrupted.
Again, if I have misstated anything, please correct me.
Now, assuming that that is what Muslims believe (and please correct me if I’m wrong), I see a logical problem. Namely, if Divine Revelation (in this case, the Old and New Testament) can become corrupted, what guarantee do we have that the Koran hasn’t become corrupted? How do we know that the Koran is true?
Now, Muslims, to my knowledge, answer this by saying that Mohammad was the last prophet, and there will be no others after him, and therefore, the Koran cannot be corrupted, because there will be no other prophet to correct it, and so God would not have allowed it to become corrupted.
But, how do we know that Mohammad was to be the last prophet? What if the parts of the Koran that say, “Mohammad will be the last prophet.” were the parts that got corrupted? If the Bible (Old and New Testament) could get corrupted and require another prophet to come and “fix” things with further divine revelation, how do we know that the same hasn’t happened to the Koran already, and that there isn’t another prophet who will come along and “fix” any errors that have cropped up in the Koran?
By this argument, you could never be certain that you have truly inerrant divine revelation. There could always be errors that another prophet has to come along and fix.
Now, I’m not necessarily trying to argue that the Korans we have today are different from the original. I don’t know much in this area, but I would expect that the Korans we have today are faithful to the original (people tend to take their holy books seriously). But, Christians can and do make the same argument about the Bible–the ancient manuscripts match the faithfully translated Bibles we have today.
And, that same Bible says that, if anyone preaches another Gospel (ie: apart from the Christian Gospel), even if he receives it from an angel, let him be accursed (see Galatians 1:6-9).
The Bible says that Jesus is the Son of God, and we can find the Doctrine of the Trinity in the Bible, as well as the account of Christ’s death on the cross and subsequent resurrection. If I remember correctly, the Koran flatly rejects the Doctrine of the Trinity and Christ’s divinity. If so, then there is a contradiction between the Bible and the Koran.
So, if there are in fact contradictions between today’s Bible and Koran, that leaves us with a few possibilities:
- The Bible is inerrant/inspired, and the Koran is therefore not inerrant and inspired (two contradictory things cannot both be true, and God cannot lie, so if they contradict each other, they can’t both be inerrant or inspired). This is the Christian view.
- The Bible has become corrupted, and the Koran is inerrant/inspired. The contradictions are due to the Bible’s corruption. This is the Muslim view.
Now, Option 2 suffers from the logical problems that I outlined above. Namely, if the Bible has become corrupted, and there needed to be a new prophet and a new revelation to correct/complete it, what guarantee do we have that the same thing hasn’t happened to the Koran? How do we know that, tomorrow, another prophet won’t come out of the woodwork in some corner of the world, proclaiming the NEW divine revelation, sent by God to correct the errors that have crept into the Koran?
Again, if divine revelation can be corrupted, it’s possible that the verses in the Koran about Mohammad being the last prophet have themselves become corrupted. Remember, the Bible says that the Christian Gospel, the Christian system of belief, will be the final thing preached, and that there are to be no new/corrected Gospels.
So, essentially, both the Bible and the Koran state that their corresponding religions are the final, complete religion. One of them has to be wrong. If the Bible is wrong, and the Koran is right, then that means that the Bible has to have become corrupted. But, if that is the case, then we have no guarantee that the Koran hasn’t also become corrupted, and that there is or will be another holy book to correct/supplement the Koran.
That, in a nutshell, is why I see logical problems with Islam. Please correct any errors regarding Muslim belief that I have made, and I hope that this post has been respectful of Islam–I think that there are a lot of things about you guys that are very admirable–for example, your devotion to prayer–I often find myself saving my daily prayers till the end of the day, and become very lazy with prayer, whereas, if I remember correctly, Muslims very faithfully and devoutly pray throughout the day. I also admire the great respect you have for the Koran as your holy book-- I need to start treating my Bible the way you guys treat your Korans!
