Quran 33:6 — The Parties (Al-Ahzab)

The prophet is closer to the believers than they are to each other, and his wives are like mothers to them. The relatives ought to take care of one another in accordance with GOD's scripture. Thus, the believers shall take care of their relatives who immigrate to them, provided they have taken care of their own families first. These are commandments of this scripture.

[33:5] You shall give your adopted children names that preserve their relationship to their genetic parents. This is more equitable in the sight of GOD. If you do not know their parents, then, as your brethren in religion, you shall treat them as members of your family. You do not commit a sin if you make a mistake in this respect; you are responsible for your purposeful intentions. GOD is Forgiver, Most Merciful.

[33:7] Recall that we took from the prophets their covenant, including you (O Muhammad), Noah, Abraham, Moses, and Jesus the son of Mary. We took from them a solemn pledge.*
