English translation
4647. It was narrated from 'Aishah that she wanted to buy Barîrah to set her free, but they stipulated that her loyalty (Walâ) should be to them. She mentioned that to the Messenger of Allâh ﷺ and the Messenger of Allâh ﷺ said: "Buy her, and set her free, and loyalty (Walâ) belongs to the one who sets the slave free." Some meat was brought to the Messenger of Allâh ﷺ and it was said that this had been given in charity to Barîrah. He said: "It is charity for her, and a gift for us." And she was given the choice. (Sahih)
