Sahih al-Bukhari 5498

It is related that the grandfather of 'Abaya ibn Rifa' ibn Rafi' ibn Khadij said, "We were with the Prophet, may Allah bless him and grant him peace, at Dhu'l-Hulayfa. The people were afflicted by hunger and we had seized some camels and sheep as booty. The Prophet, may Allah bless him and grant him peace, was somewhat behind the people and they hurried and slaughtered and set up the pots. The Prophet, may Allah bless him and grant him peace, reached them and ordered the pots to be emptied. Then he carried out the division. He made ten sheep equal to a camel. One of the camels fled. There were few horses among the people. The people went after it until they became exhausted. One of the men aimed an arrow at it and Allah stopped the camel. Then the Prophet, may Allah bless him and grant him peace, said, 'Some of these animals are wild like wild animals. If you loose control over them, then do as this man did.'" My grandfather said, "We expect - or fear - that we may meet the enemy tomorrow and not have any knives. Can we slaughter with reeds?" He said, "Use whatever makes the blood flow and eat it when the Name of Allah has been mentioned over it. Do not [slaughter] with a tooth or nail, and I will tell you about that. The tooth is a bone and the nail is the knife of the Abyssinians.'"
