The utensils of Magians and (eating) dead flesh

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 ﷺ 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"

حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ حَيْوَةَ بْنِ شُرَيْحٍ، قَالَ حَدَّثَنِي رَبِيعَةُ بْنُ يَزِيدَ الدِّمَشْقِيُّ، قَالَ حَدَّثَنِي أَبُو إِدْرِيسَ الْخَوْلاَنِيُّ، قَالَ حَدَّثَنِي أَبُو ثَعْلَبَةَ الْخُشَنِيُّ، قَالَ أَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّا بِأَرْضِ أَهْلِ الْكِتَابِ، فَنَأْكُلُ فِي آنِيَتِهِمْ، وَبِأَرْضِ صَيْدٍ، أَصِيدُ بِقَوْسِي، وَأَصِيدُ بِكَلْبِي الْمُعَلَّمِ، وَبِكَلْبِي الَّذِي لَيْسَ بِمُعَلَّمٍ. فَقَالَ النَّبِيُّ ﷺ " أَمَّا مَا ذَكَرْتَ أَنَّكَ بِأَرْضِ أَهْلِ كِتَابٍ فَلاَ تَأْكُلُوا فِي آنِيَتِهِمْ، إِلاَّ أَنْ لاَ تَجِدُوا بُدًّا، فَإِنْ لَمْ تَجِدُوا بُدًّا فَاغْسِلُوهَا وَكُلُوا، وَأَمَّا مَا ذَكَرْتَ أَنَّكُمْ بِأَرْضِ صَيْدٍ، فَمَا صِدْتَ بِقَوْسِكَ، فَاذْكُرِ اسْمَ اللَّهِ وَكُلْ، وَمَا صِدْتَ بِكَلْبِكَ الْمُعَلَّمِ، فَاذْكُرِ اسْمَ اللَّهِ وَكُلْ، وَمَا صِدْتَ بِكَلْبِكَ الَّذِي لَيْسَ بِمُعَلَّمٍ، فَأَدْرَكْتَ ذَكَاتَهُ، فَكُلْهُ ".
