Abu Qilahab reported from Abu Asma Rahabi from Abu Tha’labah Khushanni (RA) that he submitled, “0 Messenger of Allah, we are in the land of the people of the Scripture. We cook in their vessels and drink from their utensils.” He said, “If you do not find vessels other than that then wash them with water.” He submitted again, “0 Messenger of Allah, in this land, there are games. How do we act?” He said, “If you set out your trained dog and say Bismillah and it kills (a game) then eat it. If the dog is untrained then slaughter the game. And if you cast your arrow, saying Bismillah, and it kills then eat it.’
