Bulugh al-Maram, Book 12, Hadith 1373 (English) ⓘ

'Adi bin Hatim (RAA) narrated, 'The Messenger of Allah said to me, "When you set off your dog, mention Allah's Name (Say Bismillah), and if it catched anything for you and come up to it while it is still alive slaughter it; if you come up to it when the dog has killed it but not eaten any of it, eat it. If you find another dog with yours and the game has been killed, do not eat, for you do not know which of them killed the animal. When you shoot your arrow, mention Allah's Name and if the game goes out of sight for a day and you find it without any marks except for that arrow, eat if you wish, but if you find it drowned in water do not eat it." Agreed upon, and the wording is from Muslim.

وَعَنْ عَدِيِّ بنِ حَاتِمٍ ‏- رضى الله عنه ‏- قَالَ: قَالَ لِي رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ "إِذَا أَرْسَلَتَ كَلْبَكَ فَاذْكُرِ اسْمَ اَللَّهِ, فَإِنْ أَمْسَكَ عَلَيْكَ فَأَدْرَكْتَهُ حَيًّا فَاذْبَحْهُ, وَإِنْ أَدْرَكْتَهُ قَدْ قُتِلَ وَلَمْ يُؤْكَلْ مِنْهُ فَكُلْهُ, وَإِنْ وَجَدْتَ مَعَ كَلْبِكَ كَلْبًا غَيْرَهُ وَقَدْ قُتِلَ فَلَا تَأْكُلْ: فَإِنَّكَ لَا تَدْرِي أَيَّهُمَا قَتَلَهُ, وَإِنْ رَمَيْتَ سَهْمَكَ فَاذْكُرِ اسْمَ اَللَّهِ, فَإِنْ غَابَ عَنْكَ يَوْماً, فَلَمْ تَجِدْ فِيهِ إِلَّا أَثَرَ سَهْمِكَ, فَكُلْ إِنْ شِئْتَ, وَإِنْ وَجَدْتَهُ غَرِيقاً فِي اَلْمَاءِ, فَلَا تَأْكُلْ" } مُتَّفَقٌ عَلَيْهِ, وَهَذَا لَفْظُ مُسْلِمٍ (1746)‏.‏ ‏1 ‏- صحيح رواه البخاري ( 5484 )‏، ومسلم ( 1929 )‏ ( 6 )‏.‏
