Sahih Muslim 1929 c
'Adi b. Hatim reported that he asked the Messenger of Allah (ﷺ) about (hunting) with the help of an arrow having a stub end. He said:
If it strikes (the game) with its point, then eat, but if it strikes flatly and it dies, that is Waqidh (beaten into death), do not eat that. I asked the Messenger of Allah (ﷺ) about (hunting with the help of) dogs, whereupon he said. When you send your dog (for hunting) reciting the name of Allah, then eat (the game), but if some part of it is eaten (by the dogs, then do not eat that, for it (your dog) has caught that (the-game) for itself. I (again) said: If I find along with my dog another dog, and do not know which of (the dogs) has caught (the game). then (what should I do)? Thereupon he ('Allah's Messenger) said: Then don't eat that, for you recited the name of Allah on your dog and not on the other one.
وَحَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ اللَّهِ بْنِ،
 أَبِي السَّفَرِ عَنِ الشَّعْبِيِّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم
 عَنِ الْمِعْرَاضِ فَقَالَ ‏"‏ إِذَا أَصَابَ بِحَدِّهِ فَكُلْ وَإِذَا أَصَابَ بِعَرْضِهِ فَقَتَلَ فَإِنَّهُ وَقِيذٌ فَلاَ
 تَأْكُلْ ‏"‏ ‏.‏ وَسَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الْكَلْبِ فَقَالَ ‏"‏ إِذَا أَرْسَلْتَ كَلْبَكَ
 وَذَكَرْتَ اسْمَ اللَّهِ فَكُلْ فَإِنْ أَكَلَ مِنْهُ فَلاَ تَأْكُلْ فَإِنَّهُ إِنَّمَا أَمْسَكَ عَلَى نَفْسِهِ ‏"‏ ‏.‏ قُلْتُ فَإِنْ
 وَجَدْتُ مَعَ كَلْبِي كَلْبًا آخَرَ فَلاَ أَدْرِي أَيُّهُمَا أَخَذَهُ قَالَ ‏"‏ فَلاَ تَأْكُلْ فَإِنَّمَا سَمَّيْتَ عَلَى كَلْبِكَ
 وَلَمْ تُسَمِّ عَلَى غَيْرِهِ ‏"‏ ‏.‏
