It was narrated that 'Adiyy bin Hatim said: "I said: 'O Messenger of Allah, I release my trained dogs and they catch (game) for me; can I eat It? He said: 'When you release your trained dogs and they catch (game) for you, then eat.' I said: 'Even if they kill it.' He said: 'So long as no other dogs have joined them." I said: 'I shoot with the Mirad. And they penetrate (the game).' He said 'If they penetrate it, then eat, but if the broad said strikes it, then do not eat.""
