Mohammed, having derived his idea of heaven indirectly from the Chaldean accounts of the Garden of Eden, and that of the devil from the dualism of Persian mythology, borrowed the name and description of the place of torment from the Jews, who denominated hell Ge-Hinnom, literally, the “Vale of Hinnom,” from a fertile and pleasant valley near Jerusalem, which, however, was rendered execrable in spite of its attractions, on account of its being the home of the relentless Moloch, upon whose altar was periodically immolated the flower of the Hebrew youth. The rabbinical division into seven stages, entered by as many gates, and each set apart for a different degree of punishment, is adopted without sensible alteration. If reference to Paradise is seldom made in the Koran, the details of the tortures of the damned are, on the other hand, remarkable for their vividness and frequency, and, conceived by the flights of an unbridled imagination, are delineated with all the earnestness of a mind convinced of their fearful reality. The Koran, like the Zendavesta, which enjoins the tilling of the soil as an indispensable religious duty, recommends the practice of agricultural pursuits, the extension of commerce, and the foundation and development of every species of manufacturing industry. The encouragement of these occupations, by representing them as praiseworthy and agreeable to God, with a view to their general adoption by a people who had hitherto considered trade and manual labor as contemptible, was naturally a task of considerable difficulty. But expectations of pecuniary advantage, joined to the prospect of individual distinction and national glory, speedily removed this prejudice; especially in a society which contained no privileged classes, and recognized none of the artificial and depressing obligations of feudalism. In consequence of this wise recommendation, the restrictions of caste--which had never prevailed in Arabia to the extent common to the kingdoms of Asia, probably because it possessed no hierarchy and no organized system of government--were eradicated; all employments of an honorable character were placed upon an equal footing; and the merchant and the artisan each enjoyed a degree of dignity, popular esteem, and social importance proportionate to his talents and success.
