Professor John Esposito pointed out in his book, Islam: The Straight Path that: “Muhammad was among those great religious figures, prophets and founders of religions, whose remarkable character and personality inspired uncommon confidence and commitment. His phenomenal success in attracting followers and creating a community-state that dominated Arabia could be attributed not only to the fact that he was a shrewd military strategist but also to the fact that he was an unusual man… Muhammad’s followers found him righteous, trustworthy, pious, honest and compassionate.”
