Sahih Muslim Book - 34, Hadith - 4973

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا ابْنُ فُضَيْلٍ ، عَنْ بَيَانٍ ، عَنِ الشَّعْبِيِّ ، عَنْ عَدِيِّ بْنِ حَاتِمٍ ، قَالَ : سَأَلْتُ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قُلْتُ : إِنَّا قَوْمٌ نَصِيدُ بِهَذِهِ الْكِلاَبِ ، فَقَالَ : إِذَا أَرْسَلْتَ كِلاَبَكَ الْمُعَلَّمَةَ ، وَذَكَرْتَ اسْمَ اللهِ عَلَيْهَا ، فَكُلْ مِمَّا أَمْسَكْنَ عَلَيْكَ ، وَإِنْ قَتَلْنَ ، إِلاَّ أَنْ يَأْكُلَ الْكَلْبُ ، فَإِنْ أَكَلَ فَلاَ تَأْكُلْ ، فَإِنِّي أَخَافُ أَنْ يَكُونَ إِنَّمَا أَمْسَكَ عَلَى نَفْسِهِ ، وَإِنْ خَالَطَهَا كِلاَبٌ مِنْ غَيْرِهَا ، فَلاَ تَأْكُلْ.

It was narrated that 'Adiyy bin Hatim said: "I asked the Messenger of Allah (s.a.w) saying: 'We are a people who hunt with these dogs.' He said: 'If you release these trained dogs and mention the Name of Allah over them, then eat what they catch for you, even if they kill it, unless the dog eats some of it. If he eats some of it then do not eat of it, for I am afraid that he may have caught it for himself. And if other dogs join your dog, then do not eat (the game)."'
