أَخْبَرَنَا سَعِيدُ بْنُ عَامِرٍ ، حَدَّثَنَا عَوْفٌ ، عَنْ الْحَسَنِ ، عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" لَوْلَا أَنَّ الْكِلَابَ أُمَّةٌ مِنْ الْأُمَمِ، لَأَمَرْتُ بِقَتْلِهَا كُلِّهَا، وَلَكِنْ اقْتُلُوا مِنْهَا كُلَّ أَسْوَدَ بَهِيمٍ ".
قَالَ سَعِيدُ بْنُ عَامِرٍ : الْبَهِيمُ : الْأَسْوَدُ كُلُّهُ
