Essentially 90 % of Muslim rejection of the Bible and belief in the Quran is due to the trinity. They believe that because Muhammad rejected the trinity, and instituted a strict and pure monotheism, in their minds he must be a prophet from God. To them he is Moses like figure saving Arabia and the world from polytheism. If the trinity doctrine never arose, Islam may never have existed. Muhammad not only rejected the trinity, but also the fact that Jesus is the son of God. That God has an only begotten son is abhorrent to them. It denies that Christ was even crucified. He only "appeared" to have been crucified, which is similar to Gnosticism. He is relegated to the status of a mere prophet. Yet even the prophetic status of Christ is contadictory, since athough they claim to belive in Christ as the messiah, it has no real meaning since they reject all of his teachings. They reinstituted polygamy, forbid pork, make repetative prayers and wash their hands before prayer [similar to the Pharisees]. There is no "love your enemy" in Islam. In many ways, Islam resembles an expansionist Judaism through jihad. They also believe in a literal hellfire.
