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
