It was narrated from 'Aishah that she wanted to buy Barirah, but her masters stipulated that her Wala' should go to them. She mentioned that to the Prophet and he said:

"Buy her and set her free, for Al-Wala' is to the one who sets the slave free." Some meat was brought and it was said: "This is some of that which was given in charity to Barirah." He said: "It is charity for her and a gift for us." And the Messenger of Allah gave her the choice, and her husband was a free man.

أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، عَنْ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، أَنَّهَا أَرَادَتْ أَنْ تَشْتَرِيَ، بَرِيرَةَ فَاشْتَرَطُوا وَلاَءَهَا فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ " اشْتَرِيهَا وَأَعْتِقِيهَا فَإِنَّ الْوَلاَءَ لِمَنْ أَعْتَقَ " . وَأُتِيَ بِلَحْمٍ فَقِيلَ إِنَّ هَذَا مِمَّا تُصُدِّقَ بِهِ عَلَى بَرِيرَةَ . فَقَالَ " هُوَ لَهَا صَدَقَةٌ وَلَنَا هَدِيَّةٌ " . وَخَيَّرَهَا رَسُولُ اللَّهِ ﷺ وَكَانَ زَوْجُهَا حُرًّا .
