Sunan Ibn Majah Book 10, Hadith 58 Next Hadith → "The husband of Barirah was a slave called Mughith. It is as if I can see him now, walking behind her and weeping, with tears running down his cheeks. The Prophet (ﷺ) said to 'Abbas: 'O Abbas, are you not amazed by the love of Mughith for Barirah, and the hatred of Barirah for Mughith?' And the Prophet said to her: Why don’t you take him back, for he is the father of your child?' She said: 'O Messenger of Allah, are you commanding me (to do so)?' He said: 'No, rather I am interceding.' She said: 'I have no need of him.' "
