Sunan Ibn Majah, Book 10, Hadith 2152 (In-Book) ⓘ
It was narrated from Aishah that: she freed Barirah and the Messenger of Allah gave her the choice, and she (Barirah) had a free husband.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ بْنِ يَزِيدَ، عَنْ عَائِشَةَ، أَنَّهَا أَعْتَقَتْ بَرِيرَةَ فَخَيَّرَهَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَكَانَ لَهَا زَوْجٌ حُرٌّ .
