I saw Allah's Messenger (ﷺ) cutting part of the shoulder of mutton with a knife. He ate of it and then was called for prayer whereupon he got up and put down the knife and offered the prayer without performing new ablution.
Sahih al-Bukhari Book 70, Hadith 50
← Previous Hadith We used to visit Anas bin Malik while his baker was standing (and baking). Anas would say, "Eat! I do not know that the Prophet (ﷺ) had ever seen well-baked bread till he met Allah, nor had he ever seen a roasted sheep with his own eyes."

Sahih al-Bukhari Book 70, Hadith 49 Next Hadith → 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."
