It was narrated from Ash-Sha bi that; "Adiyy bin Hatim who was neighbor, Dakhilan and Rabitan at An-Nahrain narrated that he asked the Prophet Saying:'I releaser my dog and I find another dog with my dog, and I do not know which of them caught (the game).' He said: 'Do not eat, for your only said the name of Allah over your dog, and not over any other dog.""
أَخْبَرَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ الْحَكَمِ، قَالَ حَدَّثَنَا مُحَمَّدٌ، - وَهُوَ ابْنُ جَعْفَرٍ - قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ سَعِيدِ بْنِ مَسْرُوقٍ، قَالَ حَدَّثَنَا الشَّعْبِيُّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، - وَكَانَ لَنَا جَارًا وَدَخِيلاً وَرَبِيطًا بِالنَّهْرَيْنِ - أَنَّهُ سَأَلَ النَّبِيَّ صلى الله عليه وسلم قَالَ أُرْسِلُ كَلْبِي فَأَجِدُ مَعَ كَلْبِي كَلْبًا قَدْ أَخَذَ لاَ أَدْرِي أَيَّهُمَا أَخَذَ قَالَ " لاَ تَأْكُلْ فَإِنَّمَا سَمَّيْتَ عَلَى كَلْبِكَ وَلَمْ تُسَمِّ عَلَى غَيْرِهِ " .
