Abu Dawud Book 010, Hadith Number 2842.

Chapter : On game.

Narated By 'Adi b. Hatim : I asked the Apostle of Allah (pbuh). I said: We hunt with these dogs. He replied: When you set off your dog and mention Allah's name over it, eat what it caches for you, even if it kills it, except that the dog has eaten (any of it); if the dog has eaten (any of it), do not eat, for I am afraid it has caught it only for itself.
