Ok, Sergeant Cold; it's clear that you don't like Islam or Mohammed -- but islam is a major monotheistic faith alongside Christianity: It has an amazing amount of similarities with Christianity and Judaism. Its holy texts interlap. The Allah of Islam and God of Christianity is most likely the same God.

The question is: Who is right or wrong about Mohammed and Jesus (prophet, son of God etc..)? I have chosen to believe that it is Christianity. But nobody can prove any of this with any degree of absolute certainty! That's why it's called faith! Moslems are just as passionate about their faith as we are about ours. (or in the case of some -- as uninterested!!) We should respect Muslims, just as they should respect us.

The ideal situation would be that God accepted anyone with sincere faith in him, who's tried to live a good life.
Some points in the Bible (and probably the Koran, although I haven't read it) would suggest not.. But then there is a lot of room for interpretation when reading the Bible.
