“The verses talked about other Prophets as brothers preaching the same unifying script of mankind, showing every man and woman the way to Paradise. I saw the names of Jesus, of Moses, of Abraham, of Jacob, of Noah and of course, crucially, the name of this last messenger, the last Messenger of God, Mu'hammad.”
Yusuf Islam (Cat Stevens)

"My choice of Mu’hammad 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 the religious and secular level."  
Michael H. Hart, The 100: A Ranking of the Most Influential Persons in History

"Mu'hammed was not an apparent failure. He was a dazzling success, politically as well as spiritually, and Islam went from strength
to strength to strength."
Karen Armstrong

“I wanted to know the best of the life of one who holds today an undisputed sway over the hearts of millions of mankind...I became more than ever convinced that it was not the sword that won a place for Islam in those days in the scheme of life. It was the rigid simplicity, the utter self-effacement of the Prophet the scrupulous regard for pledges, his intense devotion to his friends and followers, his intrepidity, his
fearlessness, his absolute trust in God and in his own mission.

These and not the sword carried everything before them and surmounted every obstacle. When I closed the second volume [of the Prophet’s biography], I was sorry there was not more for me to read of that great life.”
Mahatma Gandhi, published in “Young India” 1924
