"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»
