My father thinks that Muhammed was a christian, is he right? Twisted logic?

[DannyGargotuan]

He says "When I read about Muhammed and his life I see a fellow christian who loved jesus christ so much that he just couldn't accept his defeat by his enemies at that time so he came up with an alternative scenario where christ was replaced by someone else. He did his best to lead the arabs to follow the teachings of our lord jesus christ and this is enough reason to love him. I don't know why we are alienating arabs for israelis, since israelis are the descendants of the judeans who were directly responsible for the killing of our saviour, lord jesus christ."
