'A'isha (Allah be pleased with her). the wife of Allah's Messenger (ﷺ) said:

Three are the Sunan (usages) (that we came to know in case of Bairara). She was given option in regard to her husband when she was emancipated. Sbe was given meat as charity. Allah's Messenger (ﷺ) visited me when an earthen pot with meat in it was placed on the fire. He asked for food and be was given bread with ordinary meat (usually cooked in the) house. Thereupon he (Allah's Messenger (ﷺ) ) said: Don't I see the earthen pot on fire with meat in it? They said: Yes. Allah's Messenger (ﷺ) , there is meat in it which was given as charity to Barira. We did not deem it advisable that we should give you that to eat, whereupon he said: It is charity for her, but it is gift for us. Allah's Messenger (ﷺ) also said: The right of inheritance vests with one who emancipates.

وَحَدَّثَنِي أَبُو الطَّاهِرِ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي مَالِكُ بْنُ أَنَسٍ، عَنْ رَبِيعَةَ بْنِ أَبِي، عَبْدِ الرَّحْمَنِ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّهَا قَالَتْ كَانَ فِي بَرِيرَةَ ثَلاَثُ سُنَنٍ خُيِّرَتْ عَلَى زَوْجِهَا حِينَ عَتَقَتْ وَأُهْدِيَ لَهَا لَحْمٌ فَدَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم وَالْبُرْمَةُ عَلَى النَّارِ فَدَعَا بِطَعَامٍ فَأُتِيَ بِخُبْزٍ وَأُدُمٍ مِنْ أُدُمِ الْبَيْتِ فَقَالَ ‏"‏ أَلَمْ أَرَ بُرْمَةً عَلَى النَّارِ فِيهَا لَحْمٌ ‏"‏ ‏.‏ فَقَالُوا بَلَى يَا رَسُولَ اللَّهِ ذَلِكَ لَحْمٌ تُصُدِّقَ بِهِ عَلَى بَرِيرَةَ فَكَرِهْنَا أَنْ نُطْعِمَكَ مِنْهُ ‏.‏ فَقَالَ ‏"‏ هُوَ عَلَيْهَا صَدَقَةٌ وَهُوَ مِنْهَا لَنَا هَدِيَّةٌ ‏"‏ ‏.‏ وَقَالَ النَّبِيُّ صلى الله عليه وسلم فِيهَا ‏"‏ إِنَّمَا الْوَلاَءُ لِمَنْ أَعْتَقَ ‏"‏ ‏.‏
