It was narrated from Ibn ‘Abbas (رضي الله عنه) that

The husband of Bàreerah was a black slave who was called Mugheeth. I used to see him following Bareerah in the streets of Madinah, weeping for her. The Prophet (ﷺ) gave four rulings because of her. He ruled that wala' belongs to the one who manumits the slave. He gave her the choice (with regard to divorce) and he ordered her to observe 'iddah. And she received charity and gave some of it as a gift to 'A'ishah (رضي الله عنھا); she mentioned that to the Prophet (ﷺ) and he said: "It is charity for her and a gift to us."
