And there is actually a split in Islam between people who call themselves Sunnis and people who call themselves Shiites. Sunnis believe that the first caliphate was ruled under by his father-in-law, Muhammad's father-in-law, Abu Bakr. People that are Shiites believe that it's not really until the fourth caliphate that we get the real ruler, which was his son-in-law, Ali. But we could talk about that a little bit later. Why don't we talk about some of the articles of faith of somebody who calls himself a Muslim who belongs to the religion of Islam. Where do you think the most Muslims live? Do you think it's in the Middle East?
