A man may gratify his passion with his female slave in whatever way he pleases—It is lawful for a man to perform the act of Azil with his female slave without her consent, whereas he cannot lawfully do so by his wife unless with her permission. –The reason of this is that the Prophet has forbidden the act of Azil with a free woman without her consent but has permitted it to a master in the case of his female slave. Besides, carnal connexion is the right of a free woman for the gratifying of her passion, and the propagation of children (whence it is that a wife is at liberty to reject a husband who is an eunuch or impotent); whereas a slave possesses no such right.—A man, therefore, is not at liberty to injure the right of his wife, whereas a master is absolute with respect to his slave. If, also, a man should marry the female slave of another, he must not perform the act of Azil with her without the consent of her master.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "A man may gratify his passion with his female slave in whatever way he pleases—It is lawful for a man to perform the act of Azil with his female slave without her consent, whereas he cannot lawfully do so by his wife unless with her permission. –The reason of this is that the Prophet has forbidden the act of Azil with a free woman without her consent but has permitted it to a master in the case of his female slave. Besides, carnal connexion is the right of a free woman for the gratifying of her passion, and the propagation of children (whence it is that a wife is at liberty to reject a husband who is an eunuch or impotent); whereas a slave possesses no such right.—A man, therefore, is not at liberty to injure the right of his wife, whereas a master is absolute with respect to his slave. If, also, a man should marry the female slave of another, he must not perform the act of Azil with her without the consent of her master." in the context of "Volume IV, Book XLIV, pp. 600-601" to mean that wisdom is timeless.
