“His military triumphs awakened no pride nor vain glory, as they would have done had they been effected for selfish purposes. In the time of his greatest power he maintained the same simplicity of manners and appearance as in the days of his adversity. So far from affecting a regal state, he was displeased if, on entering a room, any unusual testimonials of respect were shown to him.”

Washington Irving, Orientalist
(From his book: Life of Mohammed)
