Washington Irving (1783 -1859) was an American historian, biographer, story writer, essayist and diplomat during the 19th century. He studied the temperamental qualities of Prophet Muhammad and was highly impressed with his intellect, nature, character and unmatched accomplishments during such a short span of 23 years of Prophethood.
Washington Irving says about Prophet Muhammad in his book ‘Mahomet and His Successors‘ :
“His intellectual qualities were undoubtedly of an extraordinary kind. He had a quick apprehension, a retentive memory, a vivid imagination and an inventive genius.
His military triumphs awakened no pride nor vainglory 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 testimonial of respect was shown to him.
If he aimed at universal domination it was the dominion of the faith: as to the temporal rule which grew up in his hands, he used it without ostentation, so he took no step to perpetuate it in his family.”
