Si la grandeur du dessein, la petitesse des moyens, l'immensité du résultat sont les trois mesures du génie de l'homme, qui osera comparer humainement un grand homme de l'histoire moderne à Mahomet?

‎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? The most famous men created arms, laws, and empires only. They founded, if anything at all, no more than material powers which often crumbled away before their eyes. This man moved not only armies, legislations, empires, peoples, dynasties, but millions of men in one-third of the then inhabited world; and more than that, he moved the altars, the gods, the religions, the ideas, the beliefs and the souls. Philosopher, Orator, Apostle, Legislator, Conqueror of Ideas, Restorer of Rational beliefs... The founder of twenty terrestrial empires and of one spiritual empire — that is Muhammad. As regards all standards by which human greatness may be measured, we may well ask, is there any man greater than he?
