Narrated `Aisha: The Prophet (ﷺ) did not do that (i.e., forbade the storage of the meat of sacrifices for three days) except (he did so) so that the rich would feed the poor. But later we used to keep even trotters to cook, fifteen days later. The family of Muhammad did not eat wheat bread with meat or soup to their satisfaction for three successive days.

حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَابِسٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا فَعَلَهُ إِلاَّ فِي عَامٍ جَاعَ النَّاسُ، أَرَادَ أَنْ يُطْعِمَ الْغَنِيُّ الْفَقِيرَ، وَإِنْ كُنَّا لَنَرْفَعُ الْكُرَاعَ بَعْدَ خَمْسَ عَشْرَةَ، وَمَا شَبِعَ آلُ مُحَمَّدٍ صلى الله عليه وسلم مَنْ خُبْزِ بُرٍّ مَأْدُومٍ ثَلاَثًا.
