Sahih Muslim Book - 34, Hadith - 4981

حَدَّثَنِي الْوَلِيدُ بْنُ شُجَاعٍ السَّكُونِيُّ ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ ، عَنْ عَاصِمٍ ، عَنِ الشَّعْبِيِّ ، عَنْ عَدِيِّ بْنِ حَاتِمٍ ، قَالَ : قَالَ لِي رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : إِذَا أَرْسَلْتَ كَلْبَكَ فَاذْكُرِ اسْمَ اللهِ ، فَإِنْ أَمْسَكَ عَلَيْكَ ، فَأَدْرَكْتَهُ حَيًّا فَاذْبَحْهُ ، وَإِنْ أَدْرَكْتَهُ قَدْ قَتَلَ ، وَلَمْ يَأْكُلْ مِنْهُ فَكُلْهُ ، وَإِنْ وَجَدْتَ مَعَ كَلْبِكَ كَلْبًا غَيْرَهُ ، وَقَدْ قَتَلَ فَلاَ تَأْكُلْ ، فَإِنَّكَ لاَ تَدْرِي أَيُّهُمَا قَتَلَهُ ، وَإِنْ رَمَيْتَ سَهْمَكَ ، فَاذْكُرِ اسْمَ اللهِ ، فَإِنْ غَابَ عَنْكَ يَوْمًا ، فَلَمْ تَجِدْ فِيهِ إِلاَّ أَثَرَ سَهْمِكَ ، فَكُلْ إِنْ شِئْتَ ، وَإِنْ وَجَدْتَهُ غَرِيقًا فِي الْمَاءِ ، فَلاَ تَأْكُلْ.

It was narrated that 'Adiyy bin Hatim said: "The Messenger of Allah (s.a.w) said to me: 'If you release your dog and mention the Name of Allah, if he catches something for you and you find it alive, then slaughter it; if you find he has killed it but has not eaten any of it, then eat it. If you find another dog with your dog and it (the game) has been killed, then do not eat, for you do not know which of them killed it. If you shoot your arrow and mention the Name of Allah, then (the game) vanishes from your sight for a day, and you only find the mark of your arrow on it, then eat if you wish, but if you find it drowned in water, then do not eat it."'
