Prohibited to you [for marriage] are your mothers, your daughters, your sisters, your father's sisters, your mother's sisters, your brother's daughters, your sister's daughters, your [milk] mothers who nursed you, your sisters through nursing, your wives' mothers, and your step-daughters under your guardianship [born] of your wives unto whom you have gone in. But if you have not gone in unto them, there is no sin upon you. And [also prohibited are] the wives of your sons who are from your [own] loins, and that you take [in marriage] two sisters simultaneously, except for what has already occurred. Indeed, Allah is ever Forgiving and Merciful. 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 any of you cannot afford to marry a free believing woman let him marry one of his believing maids whom he possesses. God best knows your faith. You are one of another. So marry them with their owner's permission, and give them their dower according to what is fair, neither committing fornication nor taking secret paramours. And if, after they are married, they commit adultery they shall have half the punishment prescribed for a free woman. This is for those of you who fear lest he should fall into sin. But that it is better for you to practise self restraint. God is most forgiving and merciful. 25
