History has recorded fine details of Muhammad’s life as well as his sublime and humane dealing with people. Michael Hart stated in his book “The 100; A Ranking of History”
"Of humble origins, Muhammad founded and promulgated one of world’s great religions and became an immensely effective political leader. Today, centuries after his death, his influence is still powerful and pervasive. The majority of persons in this book, had the advantage of being born and raised in centers of civilization, highly cultured and politically pivotal nations”.
Muhammad however was born in the year 570 CE, in city of Mecca, in southern Arabia, at time a backward area of the world, far from the centers of trade, art and learning.”
“It is probable that the relative influence of Muhammad on Islam has been larger than the combined influence of Jesus Christ and St. Paul on Christianity. On the purely religious level, then it seems likely that Muhammad has been as influential in human history as Jesus.”
