The word Islam means "submission". It describes the spiritual state of the believer, in fact, one of the reasons Islam is so widespread and spreading in the developing world is it's utter simplicity. To be a Muslim, one only need do three things: Admit that there is only one God, whose name is Allah, proclaim Muhammed as his last and final prophet, and state that one will live his life in submission to God according to the words of his Prophet as is found in the Koran. Submission to the Will of God is a spiritual precept found in all the major religions. I don't see how anyone who claims to be a Christian can answer "No!" when asked if Christianity requires him to submit to God's Will:

Since you seem to suffer from ignorance of your own religion, I recommend reading William James' Varieties of Religious Experience. Christianity and Islam are both Semetic-tradition religions. It's creed is logically simliar, altho the characters are different, One is to submit to God thru the Savior and lives one's life in submission to His Will by following the Bible. Same mumbo-jumbo, different cast of characters.
