I'm sorry zstep, this simply isn't true... Muslims believe in all the prophets and messengers of God (including Jesus), equally, without distinction, wherever they may have appeared. In the Quran (2:136, 285, and 3:83 etc..) it is stated clearly: "We make no distinction between them".in Islam, Jesus is sinless (I'm pretty sure) and more holy than the Prophet Muhammad.
But at last the time came to unite all the nations upon a single religion so that mankind may live as one nation. For this purpose Muslims believe in the Prophet Muhammad, (not Christ) to whom Allah gave his final and greatest teachings for the whole world for all time to come.
Also throughout the Koran, Mohammed refutes that Jesus was the Son of God:
Sura 19:20,34, Jesus praised his birth and then said, “I am the servant of Allah.” And Allah teaches, “It is not for God to take a son unto Him.” Here we have Jesus speaking denying everything he said in the Bible.
Sura 6:102 “The originator of heavens and earth! How can He have a child, when there is for Him no consort?”
This is from Sura 19:88-92 They say: “(God) Most Gracious has begotten a son!” Indeed ye have put forth a thing most monstrous! At it the skies are ready to burst, the earth to split asunder, and the mountains to fall down in utter ruin, That they should invoke a son for (God) Most Gracious. For it is not consonant with the majesty of (God) Most Gracious that He should beget a son.”
“They say, `God has taken to Him a son' .... Say: `Those who forge against God falsehood shall not prosper.”
Christ is merely a messenger of God, nothing more, nothing less. He is not God nor the son of God as claimed by the Quran. This is only one of the many contradidtions from the bible...
