So he went to the Prophet (ﷺ) or sent someone to him The Prophet (ﷺ) permitted (them) to eat it.
Sahih al-Bukhari Book 72, Hadith 27
← Previous Hadith Once during the lifetime of Allah's Messenger (ﷺ) we offered some animals as sacrifices. Some people slaughtered their sacrifices before the (Id) prayer, so when the Prophet (ﷺ) finished his prayer, he saw that they had slaughtered their sacrifices before the prayer. He said, "Whoever has slaughtered (his sacrifice) before the prayer, should slaughter (another sacrifice) in lieu of it; and whoever has not yet slaughtered it till we have prayed; should slaughter (it) by mentioning Allah's Name."

Sahih al-Bukhari Book 72, Hadith 26 Next Hadith → that Ka`b had a slave girl who used to graze his sheep on a small mountain, called "Sl'a", situated near the market. Once a sheep was dying, so she broke a stone and slaughtered it with it. When they mentioned that to the Prophet, he, permitted them to eat it.
