Unbridled authority had in fact corrupted him. All those who did not adhere to his cause committed in his eyes the crime of opposing the will of God. To a man empowered by a special commission like his, the ordinary restraints of morality could not apply. Hence also, if he required a larger number of wives than was permitted to any other Moslem, a special revelation was produced to justify the excess. This was one of the weakest points in the prophet's character. Instead of setting an example to the community, he was driven to justify his self-indulgence by means which were nothing short of a perversion of religion to his own ends. There would have been nothing reprehensible, considering his age and country, in his indulgence in polygamy, had he observed any kind of moderation as to its extent. Where he happened to take a fancy to a woman, and that woman did not object to him, the moral sense of his countrymen would not have revolted by his taking her to wife. But it was revolted by the unrestricted freedom with which he added wife to wife, and concubine to concubine; a freedom so great as to degenerate into mere debauchery. He married women whom he had never seen, and who were sometimes already married. Mere beauty seems to have justified in his own eyes the addition of a new member to his harem, and there could be no pretence of real affection in the case of the women whom, without previous acquaintance, he took to his matrimonial bed. Exclusive of Khadija, the total number of his wives was thirteen, of whom nine survived him. He had also three concubines. That his procedure scandalized the faithful is shown by the necessity he felt of defending it by the pliant instrument of revelation. Not only did he obtain from God a special law entitling him to exceed the usual number of wives; other peculiarities in his conduct were justified, either by an _ex post facto_ decision applicable to all, or by an appeal to his extraordinary rights in his character of prophet. He had, for example conceived a desire to possess Zaynab, the wife of his adopted son Zayd. Zayd obligingly divorced her, and received the greatest favor from the prophet for this friendly conduct. Zaynab made it a condition of her compliance that the union with Mahomet should be sanctioned by revelation, and this sanction was of course procured. Marriage with an adopted son's wife was somewhat shocking, and the following reference in the Koran indicates the manner in which the affair was regarded:
