Islam is a voluntary relationship between individuals and their creator, Allah. It is a monotheistic religion that believes Allah is the one true God and creator of the universe. Muslims follow the teachings of Muhammad, who they believe was the final prophet sent by Allah. The Quran is the holy book of Islam containing Allah's revelations to Muhammad. 
Muslims believe in one God, angels, prophets, the Day of Judgment, and life after death. They believe Allah created the universe for a purpose and that humans were created to worship Allah according to his law. True faith involves submitting one's will to Allah alone.
