Narrated `Aisha:Three principles were established because of Barira: (i) When Banra was manumitted she was given the option (to remain with her slave husband or not). (ii) Allah's Messenger (ﷺ) said "The Wala of the slave) is for the one who manumits (the slave). (iii) When Allah's Messenger (ﷺ) entered (the house), he saw a cooking pot on the fire but he was given bread and meat soup from the soup of the home. The Prophet (ﷺ) said, "Didn't I see the cooking pot (on the fire)?" It was said, "That is the meat given in charity to Barira, and you do not eat the (things given in) charity." The Prophet (ﷺ) said, "It is an object of charity for Barira, and it is a present for us."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ فِي بَرِيرَةَ ثَلاَثُ سُنَنٍ عَتَقَتْ فَخُيِّرَتْ، وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْوَلاَءُ لِمَنْ أَعْتَقَ ". وَدَخَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَبُرْمَةٌ عَلَى النَّارِ، فَقُرِّبَ إِلَيْهِ خُبْزٌ وَأُدْمٌ مِنْ أُدْمِ الْبَيْتِ فَقَالَ " لَمْ أَرَ الْبُرْمَةَ ". فَقِيلَ لَحْمٌ تُصُدِّقَ عَلَى بَرِيرَةَ، وَأَنْتَ لاَ تَأْكُلُ الصَّدَقَةَ قَالَ " هُوَ عَلَيْهَا صَدَقَةٌ، وَلَنَا هَدِيَّةٌ ".
