33:6The Prophet is more caring of the believers than they are of themselves, and his wives are mothers to them. And blood-relatives are closer to one another in God’s Book than the believers or the emigrants, though you should do good to your friends. That is inscribed in the Book.

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.

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.

33:61They are cursed; wherever they are found, they should be captured and killed outright.
