Abdullah bin Abbas reported,

When Barirah was given the choice, I saw her husband following her through the streets of Madinah with tears streaming down his beard. He spoke to Abbas, asking him to intercede with the Prophet ﷺ on his behalf.The Messenger of Allah ﷺ said to Barirah, "He is your husband."She replied, "Are you commanding me to take him back, Messenger of Allah?"He said, "I am only interceding."She said, "Then I have no need of him."So he gave her the choice, and she chose herself. He was a slave belonging to the family of Mughira, called Mughith.

حدثنا هشيم أنبأنا خالد عن عكرمة

عن ابن عباس قال

لما خيرت بريرة رأيت زوجها يتبعها في سكك المدينة ودموعه تسيل على لحيته فكلم العباس ليكلم فيه النبي ﷺ فقال رسول الله ﷺ لبريرة إنه زوجك فقالت تأمرني به يا رسول الله قال إنما أنا شافع قال فخيرها فاختارت نفسها وكان عبدا لآل المغيرة يقال له مغيث
