It was narrated from 'Adiyy bin Hatim that he asked the Messenger of Allah about hunting and he said:
"When you release your arrow or your dog, mention the name of Allah, and when your arrow kills (the game), then eat." He said: "What if it gets away from me for a night, O Messenger of Allah?" He said: "If you find your arrow and you do not find the mark of anything else, then eat it. But if it falls into the water, do not eat it."
