It was Narrated from 'Adiyy bin Hatim the he asked the Messenger of Allah :
I release my trained dog and he catches (game). He said: If you release the trained dog and you say the name of Allah over him, and he catches (something), then eat. I said: Even if he kills it? He said: shoot with the Mirad. He said: If it hits (the game) with its sharp point, then eat, but if it hits it with its broad side, then do not eat
