“His military triumphs awakened no pride nor vain glory as they would have done had they been effected by selfish purposes. In the time of his greatest power he maintained the same simplicity of manner and appearance as in the days of his adversity. So far from affecting regal state, he was displeased if, on entering a room, any unusual testimonial of respect was shown to him.”Washington Irving. ('Life of Muhammad'. New York, 1920).
