Upgrading from god with a little g to Almighty God ... what a concept.
Muhammed was against Jesus and he claimed that Jesus never did die, as if he could rewrite history, as an uneducated man. Muhammed claimed that allah took him to heaven, but that he never died, and then Muhammed went on to claim that when Jesus returns he will follow Muhammed. Muhammed was anti-christ, proclaiming that he is better than Jesus, and he ordered death for any Muslim who wanted to follow Christ.
Muhammed has a bad record in my opinion.
