Forbidden to you are your mothers, and your daughters, and your sisters, and your aunts paternal and maternal, and a brother's daughters, and a sister's daughters; and your milk-mothers, and your milk-sisters; and the mothers of your wives; and your step-daughters - who are your foster children - born of your wives with whom you have consummated your marriage; but if you have not consummated your marriage, you will incur no sin [by marrying their daughters]; and [forbidden to you are] the spouses of the sons who have sprung from your loins; and [you are forbidden] to have two sisters [as your wives] at one and the same time - but what is past is past: for, behold, God is indeed much-forgiving, a dispenser of grace. 23 ۞ Also (forbidden are) women already married, except those (captives and slaves) whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek (them in marriage) with Mahr (bridal money given by the husband to his wife at the time of marriage) from your property, desiring chastity, not committing illegal sexual intercourse, so with those of whom you have enjoyed sexual relations, give them their Mahr as prescribed; but if after a Mahr is prescribed, you agree mutually (to give more), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise. 24 If one of you cannot afford to marry a believing gentlewoman (let him marry) a maid who is a believer. God is aware of your faith: The one of you is of the other; so marry them with the consent of their people, and give them an appropriate dowry. They are women (seeking) wedlock, and not lechery, nor secretly looking for paramours. But if they are married and guilty of adultery, inflict on them half the punishment (enjoined) for gentlewomen. This is for those who are afraid of doing wrong. In case they can wait, it is better for them. God is forgiving and kind. 25
