Book 21: The Book of Games and the Animals which May be Slaughtered and the Animals that Are to be Eaten (Kitab-us-Said wa'l-Dhaba'ih wa ma Yu'kalu min Al-Hayawan)
Chapter 1: Hunting with the help of trained dogs
'Adi b. Hatim reported: I said: Messenger of Allah, I set off trained dogs and they catch for me (the game) and I recite the came of Allah over it (I slaughter the game by reciting Bismillah-i-Allah-o-Akbar), whereupon he said: When you set off your trained dogs and you recited the name of Allah (while setting them off), then eat (the game). I said: Even if them (the trained dogs) kill that (the game)? He (the Holy Prophet) said: Even if these kill, but (on the condition) that no other dog, which you did not set off (along with your dogs), participates (in catching the game). I said to him: I throw Mi'rad, a heavy featherless blunt arrow, for hunting and killing (the game). Thereupon he said: When you throw Mi'rad, and it pierces, then eat, but if it falls flatly (and beats the game to death), then do not eat that.
