In 1978, historian Michael Hart wrote a book entitled, The One Hundred: A Ranking of the Most Influential Persons in History. Translated into over fifteen languages, Hart stirred controversy by giving the honor of Most Influential Person in History to Muhammad. He states, “My choice of Muhammad to lead the list of the world's most influential persons may surprise some readers and may be questioned by others, but he was the only man in history who was supremely successful on both religious and secular levels.”[1] Who was this man that one out of every four people in the world see as the final prophet of God?[2]
