Aisha told me that Barirah came to seek her help in writing for emancipation and at that time she had
not paid any part of her price. `Aisha said to her, "Go to your masters and if they agree that I will pay
your price (and free you) on condition that your Wala' will be for me, I will pay the money." Barirah
told her masters about that, but they refused, and said, "If `Aisha wants to do a favor she could, but
your Wala will be for us." Aisha informed Allah's Messenger (ﷺ) of that and he said to her, "Buy and
manumit Barirah as the Wala' will go to the manumitted."
