"If you release your dog and other dogs over with you have not mentioned the name of Allah join him, then do not eat (what they catch), because you do not know which of them killed it (the game),"  

أَنَّهُ سَأَلَ رَسُولَ اللَّهِ ﷺ عَنِ الصَّيْدِ فَقَالَ إِذَا أَرْسَلْتَ كَلْبَكَ فَخَالَطَتْهُ أَكْلُبٌ لَمْ تُسَمِّ عَلَيْهَا فَلاَ تَأْكُلْ فَإِنَّكَ لاَ تَدْرِي أَيَّهَا قَتَلَهُ  

"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 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»
