Upon the prophet's return into the town, while he was laying by his armor and washing himself, Gabriel came and asked him, "Have you laid by your arms? we have not laid by ours; go and attack them," pointing to the Koraidites, a Jewish tribe confederated against him. Whereupon Mahomet went immediately, and besieged them so closely in their castles that after twenty-five days they surrendered at discretion. He referred the settlement of the conditions to Saad, son of Moad; who being wounded by an arrow at the ditch, had wished he might only live to be revenged. Accordingly, he decreed that all the men, in number between six and seven hundred, should be put to the sword, the women and children sold for slaves, and their goods given to the soldiers for a prey. Mahomet extolled the justice of this sentence, as a divine direction sent down from the seventh heaven, and had it punctually executed. Saad, dying of his wound presently after, Mahomet performed his funeral obsequies, and made a harangue in praise of him. One Salam, a Jew, having been very strenuous in stirring up the people against the prophet, some zealous Casregites desired leave to go and assassinate him. Permission being readily granted, away they went to the Jew's house, and being let in by his wife, upon their pretending they were come to buy provisions, they murdered him in his bed, and made their escape. Toward the end of this year Mahomet, going into the house of Zaid, did not find him at home, but happened to espy his wife Zainab so much in dishabille as to discover beauties enough to touch a heart so amorous as his was. He could not conceal the impression made upon him, but cried out, "Praised be God, who turneth men's hearts as he pleases!" Zainab heard him, and told it to her husband when he came home. Zaid, who had been greatly obliged to Mahomet, was very desirous to gratify him, and offered to divorce his wife. Mahomet pretended to dissuade him from it, but Zaid easily perceiving how little he was in earnest, actually divorced her. Mahomet thereupon took her to wife, and celebrated the nuptials with extraordinary magnificence, keeping open house upon the occasion. Notwithstanding, this step gave great offence to many who could not bring themselves to brook that a prophet should marry his son's wife; for he had before adopted Zaid for his son. To salve the affair, therefore, he had recourse to his usual expedient: Gabriel brought him a revelation from heaven, in which God commands him to take the wife of his adopted son, on purpose that forever after believers might have no scruple in marrying the divorced wives or widows of their adopted sons; which the Arabs had before looked upon as unlawful. The apostle is even reproved for fearing men in this affair, whereas he ought to fear God. (_Koran_, chapter xxxiii.)
