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 ۞ You are forbidden to marry married women except your slave-girls. This is the decree of God. Besides these, it is lawful for you to marry other women if you pay their dower, maintain chastity and do not commit indecency. If you marry them for the appointed time you must pay their dowries. There is no harm if you reach an understanding among yourselves about the dowry, God is All-knowing and 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
