[166] [“The Arabs say that Mohammed, whilst on the road from Medina to Mecca, one day happened to see a widow woman sitting before her house, and asked how she and her three sons were; upon which the troubled woman (for she had concealed one of her sons on seeing Mohammed’s approach, lest he, as is customary when there are three males of a family present, should seize one and make him do porterage), said, ‘Very well; but I’ve only two sons!’ Mohammed, hearing this, said to the woman, reprovingly, ‘Woman, thou liest! thou hast three sons; and for trying to conceal this matter from me, henceforth remember that this is my decree,--that the two boys whom thou hast not concealed shall multiply and prosper, have fair faces, become wealthy, and reign lords over all the earth; but the progeny of your third son shall, in consequence of your having concealed him, produce _seedis_ as black as darkness, who will be sold in the market like cattle, and remain in perpetual servitude to the descendants of the other two.’” This is the Arab theory of the Negro’s origin, mentioned in _What led to the Discovery of the Source of the Nile_, by J. H. Speke, p. 341, London, 1864.--EDITOR.]
