It was narrated from 'Aishah that she bought Barirah from some of the Ansar who stipulated that her Wala' should go to them. The Messenger of Allah said:

"Al-Wala' is to the one who did the favor (of setting the slave free)." The Messenger of Allah gave her the choice, as her husband was a slave. And she gave some meat to 'Aishah as a gift, and the Messenger of Allah said: "Why don't you give me some of this meat?" 'Aishah said: "It was given in charity to Barirah." He said: "It is a charity for her, and a gift for us."

أَخْبَرَنَا الْقَاسِمُ بْنُ زَكَرِيَّا بْنِ دِينَارٍ، قَالَ حَدَّثَنَا حُسَيْنٌ، عَنْ زَائِدَةَ، عَنْ سِمَاكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّهَا اشْتَرَتْ بَرِيرَةَ مِنْ أُنَاسٍ مِنَ الأَنْصَارِ فَاشْتَرَطُوا الْوَلاَءَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ الْوَلاَءُ لِمَنْ وَلِيَ النِّعْمَةَ ‏"‏ ‏.‏ وَخَيَّرَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَكَانَ زَوْجُهَا عَبْدًا وَأَهْدَتْ لِعَائِشَةَ لَحْمًا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لَوْ وَضَعْتُمْ لَنَا مِنْ هَذَا اللَّحْمِ ‏"‏ ‏.‏ قَالَتْ عَائِشَةُ تُصُدِّقَ بِهِ عَلَى بَرِيرَةَ ‏.‏ فَقَالَ ‏"‏ هُوَ عَلَيْهَا صَدَقَةٌ وَهُوَ لَنَا هَدِيَّةٌ ‏"‏ ‏.‏
