“If greatness of purpose, smallness of means, and astonishing results are the three criteria of a human genius, who could dare compare any great man in history with Muhammad?”

“I never understood how anyone could feel small compared with the universe. After all, man knows how overwhelmingly large it is, and a few others things besides, and that means he is not small. The fact that man has discovered all this precisely proves his greatness.”

“It is only the great men who are truly obscene. If they had not dared to be obscene, they could never have dared to be great.”

“Any woman or man who would write the truth of their lives would write a great work. But no one has dared to write the truth of their lives.”

“His readiness to undergo persecutions for his beliefs, the high moral character of the men who believed in him and looked up to him as leader, and the greatness of his ultimate achievement - all argue his fundamental integrity. To suppose Muhammad an impostor raises more problems than it solves. Moreover, none of the great figures of history is so poorly appreciated in the West as Muhammad”

“Great results, can be achieved with small forces.”
