Abu Dawud Book 9, Hadith Number 2815.

Chapter : On slaughtering an animal with a sharp white stone used as a knife flint.

Narated By Rafi’ b. Khadij : I came to the Apostle of Allah (PBUH) and said: Apostle of Allah, we shall meet the enemy tomorrow and we have no knives with us. May we kill with a sharp-edged white stone (flint) and with splinter of a staff? The Apostle of Allah (PBUH) said: Hasten in slaughtering it. When Allah’s name is mentioned you may eat what is killed by anything which causes the blood to flow except tooth and claw. I shall tell you about it. The tooth is a bone, and the claw is the knife of the Abyssinians. Some people hastened forward, they made haste and got booty, while the Apostle of Allah (PBUH) was in the rear and they set up cooking pots. The Apostle of Allah (PBUH) passed the cooking pots. He ordered to turn them over. He then divided (the spoils of war) between them, and gave them a camel for ten goats in equation. One of the camels of the people ran away, and they had no horses with them at that time. A man shot an arrow at it, and Allah prevented it from escaping. The Prophet (PBUH) said: Among animals (i.e. camels) there are some which bolt like wild animals; so when any of them does so, so with it like this.
