Mohammad was a depraved, demon-possessed psychopath who married a 6 year old girl, told people to drink camel piss, had his critics assassinated, endorsed rape, killing, and stealing, and insisted that the world is flat.

Jesus said, "The thief comes to kill, steal, and destroy. I have come so that you may have life and have it abundantly." Mohammad was one of the first Antichrists. Some say that he could be fictitious, since it would be impossible for one man to have so many mental illnesses (pedophilia, psychosis, narcissism, megalomania, etc). I think it is possible if the hand of Satan is upon someone so strongly as he was.
