Sayyiduna Adi bin Hatim (may Allah be pleased with him) said: I said: "O Messenger of Allah, we send out our dogs and they hold (the game) for us?" The Messenger of Allah (peace and blessings be upon him) said: "If they are trained and you mentioned the name of Allah, then eat." I said: "O Messenger of Allah, even if they kill it?" He (peace and blessings be upon him) said: "Even if they kill it, as long as other dogs do not join them." I said: "I shoot with the mi'rad and find something?" He (peace and blessings be upon him) said: "If you mentioned the name of Allah and it pierced, then eat; and if it killed (with its broad side), do not eat."
