Sahih Bukhari Volume 007, Book 067, Hadith Number 386.
Narrated By Adi bin Hatim : I said, "O Allah's Apostle! We let loose our trained hounds after a game?" He said, "Eat what they hunt for you." I said, "Even if they killed (the game)?" He replied, 'Even if they killed (the game)." I said, 'We also hit (the game) with the Mi'rad?" He said, "Eat of the animal which the Mi'rad kills by piercing its body, but do not eat of the animal which is killed by the broad side of the Mi'rad."
