(61) باب الصَّدَقَةِ عَلَى مَوَالِي أَزْوَاجِ النَّبِيِّ صلى الله عليه وسلم
Narrated Al-Aswad:
`Aisha intended to buy Barira (a slave-girl) in order to manumit her and her masters intended to put the condition that her Al-wala would be for them. `Aisha mentioned that to the Prophet (ﷺ) who said to her, "Buy her, as the "Wala" is for the manumitted." Once some meat was presented to the Prophet (ﷺ) and `Aisha said to him, "This (meat) was given in charity to Barira." He said, "It is an object of charity for Barira but a gift for us."
