Having settled all his worldly affairs, and given directions about his sepulture, he expired, the seventh day after his assassination, in the sixty-third year of his age, after a triumphant reign of ten years and six months. Three days after the death of Omar, Othman Ibn Affan was elected as his successor. He was seventy years of age at the time of his election. He was tall and swarthy, and his long gray beard was tinged with henna. He was strict in his religious duties, but prone to expense and lavish of his riches. "In the conquests of Syria, Persia, and Egypt," says a modern writer, "the fresh and vigorous enthusiasm of the personal companions and proselytes of Mahomet was exercised and expended, and the generation of warriors whose simple fanaticism had been inflamed by the preaching of the pseudo-prophet was in a great measure consumed in the sanguinary and perpetual toils of ten arduous campaigns." We shall now see the effect of those conquests on the national character and habits; the avidity of place and power and wealth superseding religious enthusiasm; and the enervating luxury and soft voluptuousness of Syria and Persia sapping the rude but masculine simplicity of the Arabian desert. Above all, the single-mindedness of Mahomet and his two immediate successors is at an end. Other objects besides the mere advancement of Islamism distract the attention of its leading professors; and the struggle for worldly wealth and worldly sway, for the advancement of private ends, and the aggrandizement of particular tribes and families, destroy the unity of the empire, and beset the caliphate with intrigue, treason, and bloodshed. It was a great matter of reproach against the caliph Othman that he was injudicious in his appointments, and had an inveterate propensity to consult the interests of his relatives and friends before that of the public. One of his greatest errors in this respect was the removal of Amrou ben-el-Ass from the government of Egypt, and the appointment of his own foster-brother, Abdallah Ibn Saad, in his place. This was the same Abdallah who, in acting as amanuensis to Mahomet, and writing down his revelations, had interpolated passages of his own, sometimes of a ludicrous nature. For this and for his apostasy he had been pardoned by Mahomet at the solicitation of Othman, and had ever since acted with apparent zeal, his interest coinciding with his duty.
