Abdullah bin Abbas reported,

Barirah's husband was a black slave named Mughith. The narrator said, "I used to see him following her through the streets of Medina, weeping with tears streaming down his cheeks."The Prophet ﷺ issued four rulings concerning her case. Her former owners had stipulated that they retain the right of patronage (wala) over her, but the Prophet ﷺ ruled, "The right of patronage belongs to the one who frees the slave."He gave her the choice regarding her marriage, and she chose to leave her husband. He then instructed her to observe the waiting period.She was given some charity, and she sent a portion of it as a gift to Ayesha. When this was mentioned to the Prophet ﷺ, he said, "It is charity for her and a gift to us."

عن ابن عباس

أن زوج بريرة كان عبدا أسود يسمى مغيثا. قال فكنت أراه يتبعها في سكك المدينة، يعصر عينيه عليها قال: وقضى فيها النبي ﷺ أربع قضيات: إن مواليها اشترطوا الولاء، فقضى النبي ﷺ: الولاء لمن أعتق وخيرها فاختارت نفسها، فأمرها أن تعتد، قال: وتصدق عليها بصدقة فأهدت منها إلى عائشة، فذكرت ذلك للنبي ﷺ فقال: هو عليها صدقة وإلينا هدية.
