Hazrat Adi bin Hatim (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: When you release your dog for hunting and recite Bismillah, and the dog catches the prey and kills it, then eat it. But if the dog eats from it itself, then do not eat it, because it has hunted for itself. And if other dogs, on whom Allah's name was not mentioned, join your dog in the hunt and together they catch and kill the prey, then do not eat such a prey, because you do not know which dog killed it. And if you shoot an arrow at the prey and later, after two or three days, you find the prey and there is no mark on it except the mark of your arrow, then eat such a prey. But if it has fallen into water, then do not eat it.
