It was narrated from Ibn 'Abbas that:

The husband of Barirah was a slave called Mughith. It is as if I can see him walking behind her weeping, with the tears running down onto his beard. The Prophet ﷺ said to Al-'Abbas: "O 'Abbas, are you not amazed by the love of Mughith for Barirah and the hatred of Barirah for Mughith?" The Messenger of Allah ﷺ 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: "I am just interceding." She said: "I have no need of him."

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا عَبْدُ الْوَهَّابِ، قَالَ حَدَّثَنَا خَالِدٌ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ زَوْجَ، بَرِيرَةَ كَانَ عَبْدًا يُقَالُ لَهُ مُغِيثٌ كَأَنِّي أَنْظُرُ إِلَيْهِ يَطُوفُ خَلْفَهَا يَبْكِي وَدُمُوعُهُ تَسِيلُ عَلَى لِحْيَتِهِ فَقَالَ النَّبِيُّ ﷺ لِلْعَبَّاسِ " يَا عَبَّاسُ أَلاَ تَعْجَبُ مِنْ حُبِّ مُغِيثٍ بَرِيرَةَ وَمِنْ بُغْضِ بَرِيرَةَ مُغِيثًا " . فَقَالَ لَهَا النَّبِيُّ ﷺ " لَوْ رَاجَعْتِيهِ فَإِنَّهُ أَبُو وَلَدِكِ " . قَالَتْ يَا رَسُولَ اللَّهِ أَتَأْمُرُنِي . قَالَ " إِنَّمَا أَنَا شَفِيعٌ " . قَالَتْ فَلاَ حَاجَةَ لِي فِيهِ .
