Narrated Abaya bin Rifaa: My grandfather, Rafi` said, "We were in the company of the Prophet at DhulHulaifa, and the people suffered from hunger. We got some camels and sheep (as booty) and the Prophet was still behind the people. They hurried and put the cooking pots on the fire. (When he came) he ordered that the cooking pots should be upset and then he distributed the booty (amongst the people) regarding ten sheep as equal to one camel then a camel fled and the people chased it till they got tired, as they had a few horses (for chasing it). So a man threw an arrow at it and caused it to stop (with Allah's Permission). On that the Prophet said, 'Some of these animals behave like wild beasts, so, if any animal flee from you, deal with it in the same way." My grandfather asked (the Prophet ), "We hope (or are afraid) that we may meet the enemy tomorrow and we have no knives. Can we slaughter our animals with canes?" Allah's Apostle replied, "If the instrument used for killing causes the animal to bleed profusely and if Allah's Name is mentioned on killing it, then eat its meat (i.e. it is lawful) but won't use a tooth or a nail and I am telling you the reason: A tooth is a bone (and slaughtering with a bone is forbidden ), and a nail is the slaughtering instrument of the Ethiopians."

Narrated 'Abaya bin Rafa'a bin Raft' bin Khadij: My grandfather said, "We were in the company of the Prophet at Dhul-Hulaifa. The people felt hungry and captured some camels and sheep (as booty). The Prophet was behind the people. They hurried and slaughtered the animals and put their meat in pots and started cooking it. (When the Prophet came) he ordered the pots to be upset and then he distributed the animals (of the booty), regarding ten sheep as equal to one camel. One of the camels fled and the people ran after it till they were exhausted. At that time there were few horses. A man threw an arrow at the camel, and Allah stopped the camel with it. The Prophet said, "Some of these animals are like wild animals, so if you lose control over one of these animals, treat it in this way (i.e. shoot it with an arrow)." Before distributing them among the soldiers my grandfather said, "We may meet the enemies in the future and have no knives; can we slaughter the animals with reeds?" The Prophet said, "Use whatever causes blood to flow, and eat the animals if the name of Allah has been mentioned on slaughtering them. Do not slaughter with teeth or fingernails and I will tell you why: It is because teeth are bones (i.e. cannot cut properly) and fingernails are the tools used by the Ethiopians (whom we should not imitate for they are infidels).
