Musnad Abu Ya'la al-Mawsili 149:80

'Abd al-A'la ibn Hammad narrated to us, 'Uthman ibn 'Umar narrated to us, Usamah ibn Zayd narrated to us, from al-Qasim ibn Muhammad, from 'Aishah: That Barirah was a *mukatabah* (a slave who has a contract of manumission) for some people of the Ansar. She said: I wanted to purchase her and set her free, so I ordered her to go to them and inform them. They said: "If you grant us her *wala'* (right of inheritance/patronage), we will sell her to you." I asked the Messenger of Allah (ﷺ) for a legal ruling, and he said: "Purchase her and set her free, for the *wala'* belongs only to the one who pays the price." She said: She was married to a slave. When she was set free, the Messenger of Allah (ﷺ) said to her: "Choose; if you wish, you may remain with this slave, and if you wish, you may separate from him." She said: "I have indeed separated from him." She said: The Messenger of Allah (ﷺ) entered upon me while a pot was boiling with meat. He said: "What is this, O 'Aishah?" She said: "Barirah gifted it to us; it was given to her as charity." He said: "It is charity for Barirah, and it is a gift for us."
