"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."  

أَنَّهُ سَأَلَ رَسُولَ اللَّهِ ﷺ عَنِ الصَّيْدِ قَالَ إِذَا أَرْسَلْتَ كَلْبَكَ فَذَكَرْتَ اسْمَ اللَّهِ عَلَيْهِ فَقَتَلَ وَلَمْ يَأْكُلْ فَكُلْ وَإِنْ أَكَلَ مِنْهُ فَلاَ تَأْكُلْ فَإِنَّمَا أَمْسَكَهُ عَلَيْهِ وَلَمْ يُمْسِكْ عَلَيْكَ  

[Machine] I said, "O Messenger of Allah, my land is a hunting land." He said, "When you send your dog and you mention the name of Allah, whatever it catches will be for you. But if it kills, and you eat from it, then do not let your dog eat from it, for it has only caught for itself. And if you send your dog and it joins with other dogs and catches the prey without mentioning the name of Allah, then do not eat from it, for you do not know which one of them killed it."  

قُلْتُ يَا رَسُولَ اللهِ إِنَّ أَرْضِي أَرْضُ صَيْدٍ قَالَ إِذَا أَرْسَلْتَ كَلْبَكَ وَسَمَّيْتَ فَكُلْ مَا أَمْسَكَ عَلَيْكَ كَلْبُكَ وَإِنْ قَتَلَ فَإِنْ أَكَلَ مِنْهُ فَلَا تَأْكُلْ فَإِنَّهُ إِنَّمَا أَمْسَكَ عَلَى نَفْسِهِ وَإِذَا أَرْسَلْتَ كَلْبَكَ فَخَالَطَتْهُ أَكْلُبٌ لَمْ تُسَمِّ عَلَيْهَا فَلَا تَأْكُلْ فَإِنَّكَ لَا تَدْرِي أَيُّهَا قَتَلَهُ  

[Machine] I asked the Messenger of Allah ﷺ about hunting with a dog. He said, "If you send your dog and name it, and it catches and kills prey, then eat from it. But if it eats from the prey, do not eat from it, for it has held it for itself."  

سَأَلْتُ رَسُولَ اللهِ ﷺ عَنْ صَيْدِ الْكَلْبِ؟ فَقَالَ «إِذَا أَرْسَلْتَ كَلْبَكَ وَسَمَّيْتَ فَأَخَذَ فَقَتَلَ فَكُلْ فَإِنْ أَكَلَ مِنْهُ فَلَا تَأْكُلْ فَإِنَّمَا أمْسَكَ عَلَى نَفْسِهِ»  

"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»  

I asked the Prophet (about the hunting dogs) and he replied, "If you let loose (with Allah's name) your tamed dog after a game and it hunts it, you may eat it, but if the dog eats of (that game) then do not eat it because the dog has hunted it for itself." I further said, "Sometimes I send my dog for hunting and find another dog with it. He said, "Do not eat the game for you have mentioned Allah's name only on sending your dog and not the other dog." (Using translation from Bukhārī 175)   

" إذَا أرسلتَ كلبَك المعلَّم فقتل فكُلْ، وإذَا أكلَ فلا تأكلْ، فإنّما أمسكَهُ على نفسهِ- قيلَ: أُرسلُ كلبى فأجد معه كلبًا آخرَ؟ قال: فلا تأكلْ فإنّما سَمَّيتَ على كلبك ولم تُسمِّ على كلبٍ آخرَ".  

" إذا أرْسلت كلبَك فأكل الصيدَ- فلا تأكلْ؛ فإنّما أمْسك على نفسِه؛ وإذَا أرسلته فقَتَلَ ولم يأكلْ فكُلْ، فإنما أمسَكَ على صاحبه".
