Washington Irving on Hazrat Ali
(1783-1859) Well-known as the “first American man of letters”.q "He was one of the last and worthiest of the primitive Moslems, who imbibed his religious enthusiasm from companionship with the Prophet himself, and followed to the last the simplicity of his example. He is honourably spoken of as the first Caliph who accorded some protection to Belles-Lettres. He indulged in the poetic vein himself, and many of his maxims and proverbs are preserved, and have been translated in various languages. His signet bore this inscription: 'The kingdom belongs to God'. One of his sayings shows the little value he set upon the transitory glories of this world, 'Life is but the shadow of a cloud - the dream of a sleeper'."
