There are a load of problems with Islam and the Qur’an, but I’ll keep it concise to how the Qur’an disproves itself. The Qur’an makes these points: The Gospel is the word of allah: 3:3-4 No one can change allah’s words: 18:27 Strongly implies that the Christians had the Gospel when the Qur’an was written: 7:157 Christians should judge by the Gospel: 5:47
The Qur’an also denies the death of Jesus and His divinity, which the Bible claims. So it’s in obvious contradiction. So judging by the Gospel, Islam is false. And the Gospel cannot be corrupted as the Qur’an recommends the Gospel and claims allah’s words cannot be corrupted.
Paul also gives us this warning: Galatians 1:8
But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed.
Considering the Qur’an apparently was revealed to Mohammed by an “angel”… Yeah…
What about the many contractions in the gospels? For example:

Wouldn’t it be better to just accept that your faith works for you, and other people’s faith (or lack of faith) works for them?
