Abu Ubaid · The Book of Sacrifices

I was with 'Ali b. Abi Talib on the occasion of the 'Id day. He started with the 'Id prayer before delivering the sermon, and said: Allah's Messenger (ﷺ) forbade us to eat the flesh of our sacrificial animals beyond three days.

He led us in prayer before delivering the sermon and then addressed the people saying: Allah's Messenger (ﷺ) has forbidden you to eat the flesh of your sacrificial animals beyond three nights, so do not eat that.
