33:4God did not place two hearts inside any man's body. Nor did He make your wives whom you equate with your mothers, your actual mothers. Nor did He make your adopted sons, your actual sons. These are your words coming out of your mouths. God speaks the truth, and guides to the path.

33:7Recall that We received a pledge from the prophets, and from you, and from Noah, and Abraham, and Moses, and Jesus son of Mary. We received from them a solemn pledge.

33:37When you said to him whom God had blessed, and you had favored, “Keep your wife to yourself, and fear God.” But you hid within yourself what God was to reveal. And you feared the people, but it was God you were supposed to fear. Then, when Zaid ended his relationship with her, We gave her to you in marriage, that there may be no restriction for believers regarding the wives of their adopted sons, when their relationship has ended. The command of God was fulfilled.

33:55There is no blame on them concerning their fathers, or their sons, or their brothers, or their brothers’ sons, or their sisters’ sons, or their women, or their female servants. But they should remain conscious of God. God is Witness over all things.
