It was narrated that 'Adiyy bin Hatim said: "I asked the Messenger of Allah: “I release my dog, and I find another dog with mine, and I do not know which mine, and I do not know which of them caught (the game).' He said: “do not eat it, for you said the name of Allah over your dog, but not over any other””"
