Chapter 16: The Book of Pilgrimage
Ibn Abbas (Allah be pleased with them) reported that Dhuwaib, father of Qabisa (Allah be pleased with him) narrated to him that Allah' s Messenger (ﷺ) sent under his charge the sacrificial camels, and said: If any of these is completely exhausted and you apprehend its death, then slaughter it, then dip its hoofs in its blood and imprint it on its hump; but neither you nor any one of your comrades should eat it.
Sahih Muslim 1326
