Sahih Bukhari Volume 3, Book 34, Hadith 2055

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ أَبِي السَّفَرِ، عَنِ الشَّعْبِيِّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ ـ رضى الله عنه ـ قَالَ سَأَلْتُ النَّبِيَّ صلى الله عليه وسلم عَنِ الْمِعْرَاضِ فَقَالَ ‏"‏ إِذَا أَصَابَ بِحَدِّهِ فَكُلْ، وَإِذَا أَصَابَ بِعَرْضِهِ فَلاَ تَأْكُلْ، فَإِنَّهُ وَقِيذٌ ‏"‏‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ أُرْسِلُ كَلْبِي وَأُسَمِّي، فَأَجِدُ مَعَهُ عَلَى الصَّيْدِ كَلْبًا آخَرَ لَمْ أُسَمِّ عَلَيْهِ، وَلاَ أَدْرِي أَيُّهُمَا أَخَذَ‏.‏ قَالَ ‏"‏ لاَ تَأْكُلْ، إِنَّمَا سَمَّيْتَ عَلَى كَلْبِكَ وَلَمْ تُسَمِّ عَلَى الآخَرِ ‏"‏‏.‏

Narrated By 'Adi bin Hatim : I asked Allah's Apostle about Al Mirad (i.e. a sharp-edged piece of wood or a piece of wood provided with a piece of iron used for hunting). He replied, "If the game is hit by its sharp edge, eat it, and if it is hit by its broad side, do not eat it, for it has been beaten to death." I asked, "O Allah's Apostle! I release my dog by the name of Allah and find with it at the game, another dog on which I have not mentioned the name of Allah, and I do not know which one of them caught the game." Allah's Apostle said (to him), 'Don't eat it as you have mentioned the name of Allah on your dog and not on the other dog."
