‘Adi b. Hatim told that God’s messenger said to him, “When you set off your dog mention God's name, and if it catches anything for you and you come up to it while it is still alive cut its throat; if you come up to it when the dog has killed it but not eaten any of it eat it; but if it has eaten any of it do not eat, for it has caught it only for itself. If you find another dog with yours and a kill has been made, do not eat, for you do not know which of them killed the animal. When you shoot your arrow mention God’s name and if the game goes out of your sight for a day and you find in it only the mark of your arrow eat if you wish, but if you find it drowned in water do not eat.” (Bukhari and Muslim.)
