4:3If you fear you cannot act fairly towards the orphans—then marry the women you like—two, or three, or four. But if you fear you will not be fair, then one, or what you already have. That makes it more likely that you avoid bias.

4:22Do not marry women whom your fathers married, except what is already past. That is improper, indecent, and a bad custom.

4:23Forbidden for you are your mothers, your daughters, your sisters, your paternal aunts, your maternal aunts, your brother's daughters, your sister's daughters, your foster-mothers who nursed you, your sisters through nursing, your wives' mothers, and your stepdaughters in your guardianship—born of wives you have gone into—but if you have not gone into them, there is no blame on you. And the wives of your genetic sons, and marrying two sisters simultaneously. Except what is past. God is Oft-Forgiving, Most Merciful.

4:25If any of you lack the means to marry free believing women, he may marry one of the believing maids under your control. God is well aware of your faith. You are from one another. Marry them with the permission of their guardians, and give them their recompense fairly—to be protected—neither committing adultery, nor taking secret lovers. When they are married, if they commit adultery, their punishment shall be half that of free women. That is for those among you who fear falling into decadence. But to practice self-restraint is better for you. God is Most Forgiving, Most Merciful.

4:127They ask you for a ruling about women. Say, “God gives you a ruling about them, and so does what is stated to you in the Book about widowed women from whom you withhold what is decreed for them, yet you desire to marry them, and about helpless children: that you should treat the orphans fairly.” Whatever good you do, God knows it.
