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 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
