The Prophet ﷺ said: Eat what ever is caught for you by a dog or a hawk you have trained and set off when you have mentioned Allah's name. I said: (Does this apply) if it killed (the animal)? He said: When it kills it without eating any of it, for it caught it only for you. Abu Dawud said: If a hawk eats any of it, there is no harm (in eating it). If a dog eats it, it is disapproved (to eat the meat). If it drinks blood, there is no harm (in eating it).

أَنَّ النَّبِيَّ ﷺ قَالَ مَا عَلَّمْتَ مِنْ كَلْبٍ أَوْ بَازٍ ثُمَّ أَرْسَلْتَهُ وَذَكَرْتَ اسْمَ اللَّهِ فَكُلْ مِمَّا أَمْسَكَ عَلَيْكَ قُلْتُ وَإِنْ قَتَلَ قَالَ إِذَا قَتَلَهُ وَلَمْ يَأْكُلْ مِنْهُ شَيْئًا فَإِنَّمَا أَمْسَكَهُ عَلَيْكَ

"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

"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»
