Sahih Bukhari: Hadith 7129

I asked the Prophet, "I send off (for a game) my trained hunting dogs; (what is your verdict concerning the game they hunt?" He said, "If you send off your trained hunting dogs and mention the Name of Allah, then, if they catch some game, eat (thereof). And if you hit the game with a mi'rad (a hunting tool) and it wounds it, you can eat (it).
