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 do not have the means to marry a chaste believing woman, marry your believing slave-girls. God knows best about your faith. You have the same faith. Marry them with the permission of their masters and if they are chaste and have avoided fornication and amorous activities, give them their just dowries. If after marriage they commit adultery, they should receive half of the punishment of a free woman who has committed the same crime. This is for those who fear falling into evil. It is better for you to have self-control. God is All-forgiving and All-merciful. 25
