"He entered a world that had lost its faith, and hence had lost the secret of internal peace and external order, a world that was waiting for the liberating voice of Islam. Muhammad was the exemplar of virtues, virtues both of the preacher and of the soldier; he had the eloquence, convincing power, and intensity of the preacher, and the courage, gallantry and success of the warrior. Superb in his talents and his character he ruled his time as he dominated later times. No event that has since taken place has been the same as it would have been without Muhammad. History before him and after him is completely different."
