“It was the genius of Muhammad, the spirit that he breathed into the Arabs through the soul of Islam that exalted them. That raised them out of the lethargy and low level of tribal stagnation up to the high watermark of national unity and empire. It was in the sublimity of Muhammad's deism, the simplicity, the sobriety and purity it inculcated the fidelity of its founder to his own tenets, that acted on their moral and intellectual fiber with all the magnetism of true inspiration.”
