"Mohammad's greatness is unquestionable. He was one of the most outstanding men of genius who have appeared in human history. If the social and political circumstances of his time are taken into account, he has no equal among the initiators of major historical change. Men such as Alexander, Caesar, Napoleon, Hitler, Cyrus the Great, Chengiz Khan, or Timur do not bear comparison with him. They all had the support of the armed forces and public opinion of their peoples, whereas Mohammad made his way into history with empty hands and in a hostile society."
