Mohammed’s life (biography) is an epic story. He was an orphan who rose from poverty to become the first ruler of all of Arabia. He created a new religion, new methods of war and a new political system including a legal code, the Sharia (Islamic Constitution)! These books are brief, but authoritative because most paragraphs have an index number that will allow you to go to the original source book and verify the truth of the material. Everything is based on Allah and Mohammed—the only true authorities.
