Lady Aisha (may Allah be pleased with her) narrates that Barirah (may Allah be pleased with her), a slave woman, came to me and said: My masters have made a contract of manumission with me for nine uqiyah of silver over nine years, which I will pay as one uqiyah each year, so please help me. I said: If your masters wish that I pay them the entire amount at once and set you free, and the right of wala’ (allegiance) goes to me, then I am ready to do this. She went to her masters and spoke to them about this, but they refused to give the wala’. She came to Lady Aisha (may Allah be pleased with her) and informed her of her masters’ reply, so Lady Aisha (may Allah be pleased with her) said: Then I will not pay the price. So they asked the Messenger of Allah (peace and blessings be upon him) about this and told him what (the masters) had said. The Messenger of Allah (peace and blessings be upon him) said to Lady Aisha (may Allah be pleased with her): Buy her and set her free, and stipulate the condition of wala’ with them, for the right of wala’ belongs only to the one who sets free. Then the Messenger of Allah (peace and blessings be upon him) stood up and addressed the people, praised and glorified Allah, then said: What is the matter with some people among you who stipulate conditions that are not in the Book of Allah? Any condition that is not in the Book of Allah is invalid, even if there are a hundred such conditions. The decision of Allah is the truth, and the condition of Allah is the firmest. What is the matter with some people among you that one of them says: O so-and-so! Set her free, but the wala’ will be mine? No! The wala’ belongs only to the one who sets free.
