Sunan an-Nasa'i, Volume 4, Book 27, Hadith 3477 (DarusSalam) ⓘ

It was narrated that 'Aishah, the wife of the Prophet, said: Three Sunan were established because of Barirah. One of those Sunan was that she was set free and was given the choice concerning her husband; the Messenger of Allah said: 'Al Wala' is to the one who set the slave free;' and the Messenger of Allah entered when some meat was being cooked in a pot, but bread and some condiments were brought to him. He said: 'Do I not see a pot in which some meat is being cooked?' They said: 'Yes, O Messenger of Allah, that is meat that was given in charity to Barirah and you do not eat (food given in) charity.' The Messenger of Allah said: 'It is charity for her and a gift for us.'
