Abu Dawud Book 10, Hadith Number 2851.
Narated By Abdullah ibn Amr ibn al-‘As : There was a bedouin called AbuTha’labah. He said: Apostle of Allah, I have trained dogs, so tell me your opinion about (eating) the animal they hunt. The Prophet (PBUH) said: If you have trained dogs, then eat what they catch for you. He asked: Whether it is slaughtered or not? He replied: Yes. He asked: Does it apply even if it eats any of it? He replied: Even if it eats any of it. He again asked: Apostle of Allah, tell me your opinion about my bow (i.e. the game hunted by arrow). He said: Eat what your bow returns to you, whether it is slaughtered or not. He asked: If it goes out of my sight? He replied: Even if it goes out of your sight, provided it has no stench, or you find a mark on it other than the mark of your arrow.
He asked: Tell me about the use of the vessels of the Magians when we are forced to use them. He replied: Wash them and eat in them.
