Narrated Abu Tha'laba Al-Khushani:
I came to the Prophet and said, "O Allah's Apostle! We are living in the land of the people of the Scripture, and we take our meals in their utensils, and there is game in that land and I hunt with my bow and with my trained hound and with my untrained hound." The Prophet said, "As for your saying that you are in the land of people of the Scripture, you should not eat in their utensils unless you find no alternative, in which case you must wash the utensils and then eat in them As for your saying that you are in the land of game, if you hunt something with your bow, mention Allah's Name (while hunting the game) and eat; and if you hunt something with your trained hound, mention Allah's Name on sending and eat; and if you hunt something with your untrained hound and get it alive, slaughter it and you can eat of it"
