Sahih Bukhari Volume 9, Book 97, Hadith 7399

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا فُضَيْلٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ هَمَّامٍ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، قَالَ سَأَلْتُ النَّبِيَّ صلى الله عليه وسلم قُلْتُ أُرْسِلُ كِلاَبِي الْمُعَلَّمَةَ‏.‏ قَالَ ‏"‏ إِذَا أَرْسَلْتَ كِلاَبَكَ الْمُعَلَّمَةَ وَذَكَرْتَ اسْمَ اللَّهِ فَأَمْسَكْنَ فَكُلْ، وَإِذَا رَمَيْتَ بِالْمِعْرَاضِ فَخَزَقَ فَكُلْ ‏"

Narrated By 'Adi bin Hatim : I asked the Prophet, "I send off (for a game) my trained hunting dogs; (what is your verdict concerning the game they hunt?" He said, "If you send off your trained hunting dogs and mention the Name of Allah, then, if they catch some game, eat (thereof). And if you hit the game with a mi'rad (a hunting tool) and it wounds it, you can eat (it)."
