Is there anything in the Koran that changes the fact that Mohammed had a nine year-old wife?
Or that he advocated bloody jihad?
Or that Mohammed claims that Jesus was a prophet, but not the Son of God? Since it was as a Prophet that Jesus claimed His Divinity, if Jesus isn't Divine, then he also isn't a Prophet. Yet that impossible contradiction is the teaching of Mohammed as a Prophet.
Hence: If for no other reason than this, Mohammed is a false prophet.
Which brings us back to the bonfire of the Koranic Vanities in Matthew 7.
