"I said to the Mother of the Believers: 'Did the Messenger of Allah (ﷺ) prohibit from the meat of the sacrifice?' She said: 'No, but only a few people could slaughter, so he liked that they feed those who did not slaughter. (Later) we would store a leg to eat after ten days."
Jami` at-Tirmidhi Book 19, Hadith 22
← Previous Hadith From his father that the Messenger of Allah (ﷺ) said: "I used to prohibit you from (eating) the meat of Sacrifice beyond three days so that those who have the ability would give to those who do not have it. So (now) eat as you like, feed others, and save from it."

Jami` at-Tirmidhi Book 19, Hadith 21 Next Hadith → That the Messenger of Allah (ﷺ) said: "There is no Fara' or 'Atirah." The Fara' is the first of the offspring that would be born to them, so they would slaughter it. The 'Atirah was an animal that they would slaughter during Rajab to honor the month of Rajab, since it was the first of the sacred months.
