حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، حَدَّثَنَا مُجَالِدٌ، عَنِ الشَّعْبِيِّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ مَا عَلَّمْتَ مِنْ كَلْبٍ أَوْ بَازٍ ثُمَّ أَرْسَلْتَهُ وَذَكَرْتَ اسْمَ اللَّهِ فَكُلْ مِمَّا أَمْسَكَ عَلَيْكَ ‏"‏ ‏.‏ قُلْتُ وَإِنْ قَتَلَ قَالَ ‏"‏ إِذَا قَتَلَهُ وَلَمْ يَأْكُلْ مِنْهُ شَيْئًا فَإِنَّمَا أَمْسَكَهُ عَلَيْكَ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ الْبَازُ إِذَا أَكَلَ فَلاَ بَأْسَ بِهِ وَالْكَلْبُ إِذَا أَكَلَ كُرِهَ وَإِنْ شَرِبَ الدَّمَ فَلاَ بَأْسَ بِهِ ‏.‏

Narrated Adi ibn Hatim: The Prophet (PBUH) said: Eat what ever is caught for you by a dog or a hawk you have trained and set off when you have mentioned Allah's name. I said: (Does this apply) if it killed (the animal)? He said: When it kills it without eating any of it, for it caught it only for you. Abu Dawud said: If a hawk eats any of it, there is no harm (in eating it). If a dog eats it, it is disapproved (to eat the meat). If it drinks blood, there is no harm (in eating it).
