A Ranking of the Most Influential Persons in History

Michael H. Hart of USA who wrote "The 100 most influential persons in history" and placed Prophet Muhammad (peace and blessings of God be upon him) as number one, on the top of the list
"My choice of Muhammad to lead the best 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 the religious and secular levels.
His complete biography has been authenticated and circulated amongst scholars around the world starting while he was still alive and continuing up until today. One of the first examples we quote from is from the Encyclopedia Britannica, as it confirms:
(Regarding Muhammad) "... a mass of detail in the early sources shows that he was an honest and upright man who had gained the respect and loyalty of others who were likewise honest and upright men." [Vol. 12]
