حَدَّثَنَا عَبْدُ اللَّهِ بْنُ رَجَاءٍ، أَخْبَرَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، أَنَّ عَائِشَةَ، أَرَادَتْ أَنْ تَشْتَرِيَ، بَرِيرَةَ، فَأَبَى مَوَالِيهَا إِلاَّ أَنْ يَشْتَرِطُوا الْوَلاَءَ، فَذَكَرَتْ لِلنَّبِيِّ ﷺ فَقَالَ " اشْتَرِيهَا وَأَعْتِقِيهَا، فَإِنَّمَا الْوَلاَءُ لِمَنْ أَعْتَقَ ". وَأُتِيَ النَّبِيُّ ﷺ بِلَحْمٍ فَقِيلَ إِنَّ هَذَا مَا تُصُدِّقَ عَلَى بَرِيرَةَ، فَقَالَ " هُوَ لَهَا صَدَقَةٌ، وَلَنَا هَدِيَّةٌ ".
حَدَّثَنَا آدَمُ حَدَّثَنَا شُعْبَةُ وَزَادَ فَخُيِّرَتْ مِنْ زَوْجِهَا.
