Because Allah is Satan and Muhammad was and is the False Prophet of the Book of Revelation, sent to bring us the False Word and False Religion (Islam) after he and Allah (Satan) engaged in a Satanic religious ritual of buttsex because Satan convinced him that he, Lucifer the Angel of Light, was actually god, by appearing to Muhammad in his true angelic form as the Angel of Light, a shining Being of Light and so Muhammad believed it was god and so worshiped him and gave himself to him in mind, soul and body.

The battle between Christ and Lucifer will begin with a raging War between Christianity and Islam. This war will culminate with the appointment of Peter the Roman as the next Pope, Cardinal Peter Turkson who has a strong anti-Islam position and will be because of his pending anti-Islam policies established over the Church that will lead to the great destruction of Rome as foretold in the Prophecy of the Popes... and this destruction will be brought about by Islamic Forces at the behest of Satan, whom they believe to be Allah!

All this, because one man... Muhammad, climbed into bed with Satan because he believed Satan was god...
