Sunan an-Nasa'i, Book 27, Hadith 65 (In-Book) ⓘ

It was narrated from 'Aishah that she bought Barirah from some of the Ansar who stipulated that her Wala' should go to them. The Messenger of Allah said: "Al-Wala' is to the one who did the favor (of setting the slave free)." The Messenger of Allah gave her the choice, as her husband was a slave. And she gave some meat to 'Aishah as a gift, and the Messenger of Allah said: "Why don't you give me some of this meat?" 'Aishah said: "It was given in charity to Barirah." He said: "It is a charity for her, and a gift for us."
