"I asked the Messenger of Allah about hunting with the Mirad. He said: 'whatever is struck with the sharp edge, eat, and whatever is hit with its broad side, it is an animal killed by a blow. "" He said: "And I asked him about hunting dogs. He said: 'If you release your dog and mention the name of Allah over it, then eat.,' I said: 'Even it he kills it?' He said: 'Even if he kills it?" He said: 'Even if he kills it. But if he has eaten some of it, then do not eat. And if you find another dog with your dog and he has killed (the game), then do not eat, for you only said the name of Allah over your dog, not over your dog, not over any other."' (Using translation from Nasāʾī 4274)  

سَأَلْتُ رَسُولَ اللهِ ﷺ عَنْ صَيْدِ الْمِعْرَاضِ فَقَالَ «مَا أَصَابَ بِحَدِّهِ فَكُلْ وَمَا أَصَابَ بِعَرْضِهِ فَهُوَ وَقِيذٌ» قَالَ وَسَأَلْتُهُ عَنْ كَلْبِ الصَّيْدِ فَقَالَ «إِذَا أَرْسَلْتَ كَلْبَكَ وَذَكَرْتَ اسْمَ اللهِ فَكُلْ» قُلْتُ وَإِنْ قَتَلَ؟ قَالَ وَإِنْ قَتَلَ قَالَ فَإِنْ أَكَلَ مِنْهُ فَلَا تَأْكُلْ فَإِنْ وَجَدْتَ مَعَهُ كَلْبًا غَيْرَ كَلْبِكَ وَقَدْ قَتَلَهُ فَلَا تَأْكُلْ فَإِنَّكَ إِنَّمَا ذَكَرَتِ اسْمَ اللهِ عَلَى كَلْبِكَ وَلَمْ تَذْكُرْ عَلَى غَيْرِهِ  

"If you release your dog and mention the name of Allah over him, and he kills (the game), but does not eat any of it, then eat. But if he has eaten from it, then do not eat, for he caught it for himself, and not for you." (Using translation from Nasāʾī 4275)  

أَنَّهُ سَأَلَ النَّبِيَّ ﷺ عَنِ الصَّيْدِ فَقَالَ «إِذَا أَرْسَلْتَ كَلْبَكَ وَذَكَرْتَ اسْمَ اللهِ فَقَتَلَ وَلَمْ يَأْكُلْ فَكُلْ فَإِنْ أَكَلَ مِنْهُ فَلَا تَأْكُلْ فَإِنَّمَا أَمْسَكَ عَلَيْهِ وَلَمْ يُمْسِكْ عَلَيْكَ»
