a man came to the Prophet and said: "O Messenger of Allah, I have trained dogs; advise me concerning them." He said: "Whatever your dogs catch for you, eat," I side: "Even if they kill it?" He said: "Even if they kill it. " He said: "Advise me about my bow. "He said: "Whatever your arrow returns to you, eat." He said: "Even if it gets away from you, so long as you do not find the mark of an arrow other than yours on it, or you find that it has gone rotten."(Another chain).
