عَن عدِيِّ بنِ حاتِمٍ قَالَ: قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا أَرْسَلْتَ كَلْبَكَ فَاذْكُرِ اسْمَ اللَّهِ فَإِنْ أَمْسَكَ عَلَيْكَ فَأَدْرَكْتَهُ حَيًّا فَاذْبَحْهُ وَإِنْ أَدْرَكْتَهُ قَدْ قَتَلَ وَلَمْ يَأْكُلْ مِنْهُ فَكُلْهُ وَإِنْ أَكَلَ فَلَا تَأْكُلْ فَإِنَّمَا أَمْسَكَ عَلَى نَفْسِهِ فَإِنْ وَجَدْتَ مَعَ كَلْبِكَ كَلْبًا غَيْرَهُ وَقَدْ قَتَلَ فَلَا تَأْكُلْ فَإِنَّكَ لَا تَدْرِي أَيُّهُمَا قَتَلَ. وَإِذَا رَمَيْتَ بِسَهْمِكَ فَاذْكُرِ اسْمَ اللَّهِ فَإِنْ غَابَ عَنْكَ يَوْمًا فَلَمْ تَجِدْ فِيهِ إِلَّا أَثَرَ سَهْمِكَ فَكُلْ إِنْ شِئْتَ وَإِنْ وَجَدْتَهُ غَرِيقًا فِي الْمَاءِ فَلَا تأكُلْ»

‘Adi b. Hatim told that God’s messenger said to him, “When you set off your dog mention God's name, and if it catches anything for you and you come up to it while it is still alive cut its throat; if you come up to it when the dog has killed it but not eaten any of it eat it; but if it has eaten any of it do not eat, for it has caught it only for itself. If you find another dog with yours and a kill has been made, do not eat, for you do not know which of them killed the animal. When you shoot your arrow mention God’s name and if the game goes out of your sight for a day and you find in it only the mark of your arrow eat if you wish, but if you find it drowned in water do not eat.” (Bukhari and Muslim.)
