Sahih al-Bukhari 5544

Ibn Sallām narrated to us: ʿUmar ibn ʿUbayd al-Ṭanafisī informed us, from Saʿīd ibn Masrūq, from ʿAbāyah ibn Rifāʿah, from his grandfather Rāfiʿ ibn Khadīj (may God be pleased with him), who said: “We were with the Prophet ﷺ on a journey when a camel bolted from the camels. A man shot it with an arrow and stopped it.” He then said: “They can become as wild as wild beasts; if one of them gets the better of you, deal with it in this way.” He said: “I asked, ‘Messenger of God, when we are on military expeditions and journeys, we may want to slaughter an animal but have no knives.’ He said: ‘Show me what makes the blood flow—or gush—and with God’s name mentioned over it, eat, except [what is slaughtered with] a tooth or a fingernail. The tooth is a bone, and the fingernail is the knife of the Abyssinians.’”
