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.

33:51You may defer any of them you wish, and receive any of them you wish. Should you desire any of those you had deferred, there is no blame on you. This is more proper, so that they will be comforted, and not be grieved, and be content with what you have given each one of them. God knows what is within your hearts. God is Omniscient and Clement.
