die depended the regeneration of the Arabian people, the conquest and subversion of the Byzantine and Persian empires, the impulse of modern scientific inquiry, and the future hopes of the Moslem world! Mohammed was a posthumous child. His father died while on a journey to Medina, and left to his widow Amina little save the memory of his domestic virtues, and a reputation for manly courage and unblemished integrity. The boy passed his early years, as was the custom at Mecca, with one of the tribes of the Desert, where the coarse fare and active life of the Bedouin developed and strengthened a frame naturally robust and vigorous. At the age of five he returned to his mother’s home, where, within a few months, he was left an orphan. His grandfather Abd-al-Muttalib then took charge of him until the death of the former two years afterwards, when Mohammed was taken into the family of his uncle Abu-Talib. The successive bereavements of relatives to whom he was devotedly attached had no small effect in determining the character of the future Prophet, already thoughtful and reserved beyond his years, and imparted a permanent tinge of sadness to his life. When he grew older he was employed by his uncle as a shepherd, an occupation considered by the Arabs as degrading, and only proper to be exercised by slaves and women. In his twenty-sixth year his handsome face and figure, and his reputation for honesty, which had acquired for him the flattering title of Al-Amin, “The Faithful,” attracted the attention of Khadijah, a wealthy widow and a distant relative, who made him a proposal of marriage, which he accepted. Khadijah was forty years old, and had already been twice married; yet for twenty-five years which intervened before her death--and long after she must have lost her attractiveness--Mohammed never failed in the duties of a constant and affectionate husband. She bore him six children, four girls and two boys, of whom the daughters alone survived the period of infancy. When he reached the age of forty, a great change came over Mohammed, and there appeared the first positive indication of his aversion to the established worship of his country. His mother, who seems to have been a woman of highly excitable temperament, had transmitted to him a hypersensitive condition of the nervous system, which developed occasional attacks of muscular hysteria, a disease rarely affecting the masculine sex. Long accustomed to abstinence, contemplation, and revery, he contracted the habit of seeking solitude, to muse upon the moral condition of himself and his countrymen; and as he grew older, and especially after his fortunate marriage had removed the necessity for labor, the passion for dreaming grew upon him. He often betook himself to Mount Hira, where a recluse once had his abode; and for days at a time, with but little food and depriving himself of sleep, in tears and mental agony, he strove to solve the problem of divine truth.
