Narated By Abu Tha'labat b. al-Khushani : I said: Apostle of Allah, I hunt with my trained dog, and with my untrained dog? He said: What you hunt with your trained dog, mention Allah's name (on it) and eat; and what you hunt with your untrained dog, and you find in a position that you slaughter it, then eat.
