صحيح البخاري

Narrated `Abis:

I asked `Aisha "Did the Prophet (ﷺ) forbid eating the meat of sacrifices offered on `Id-ul-Adha for more than three days" She said, "The Prophet (ﷺ) did not do this except in the year when the people were hungry, so he wanted the rich to feed the poor. But later we used to store even a trotter of a sheep to eat it fifteen days later." She was asked, "What compelled you to do so?" She smiled and said, "The family of Muhammad did not eat to their satisfaction white bread with meat soup for three successive days till he met Allah."
