أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا الْمُغِيرَةُ بْنُ سَلَمَةَ، قَالَ حَدَّثَنَا وُهَيْبٌ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ يَزِيدَ بْنِ رُومَانَ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، رضى الله عنها قَالَتْ كَانَ زَوْجُ بَرِيرَةَ عَبْدًا .
It was narrated that 'Aishah, may Allah be pleased with her, said: "The husband of Barirah was a slave."
