Narrated 'Aisha:

I bought Barira (a female slave). The Prophet ﷺ said (to me), "Buy her as the Wala' is for the manumitted." Once she was given a sheep (in charity). The Prophet ﷺ said, "It (the sheep) is a charitable gift for her (Barira) and a gift for us." Al-Hakam said, "Barira's husband was a free man." Ibn 'Abbas said, 'When I saw him, he was a slave."

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتِ اشْتَرَيْتُ بَرِيرَةَ فَقَالَ النَّبِيُّ ﷺ " اشْتَرِيهَا، فَإِنَّ الْوَلاَءَ لِمَنْ أَعْتَقَ ". وَأُهْدِيَ لَهَا شَاةٌ فَقَالَ " هُوَ لَهَا صَدَقَةٌ، وَلَنَا هَدِيَّةٌ ". قَالَ الْحَكَمُ وَكَانَ زَوْجُهَا حُرًّا، وَقَوْلُ الْحَكَمِ مُرْسَلٌ. وَقَالَ ابْنُ عَبَّاسٍ رَأَيْتُهُ عَبْدًا.
