By the way they are not called 'Islams' they are called Muslims .There is not really a leader for Muslims. Muslims' God is called Allah which is Arabic for God. Prophet Mohammed is the last prophet and is the leader of the prophets. He is a wonderful role-model to all Muslims. Their book (when i say this i mean religious book, like the Bible) is called the Qur'an which is like a guide sent from Allah to Prophet Mohammed.
