عَن عبد الله بنِ مُغفَّلٍ عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَوْلَا أَنَّ الْكِلَابَ أُمَّةٌ مِنَ الْأُمَمِ لَأَمَرْتُ بِقَتْلِهَا كُلِّهَا فَاقْتُلُوا مِنْهَا كُلَّ أَسْوَدَ بَهِيمٍ»
The Prophet (sallallahu alayhi wa sallam) said:, “Were dogs not a species of creature I should command that they all be killed; but kill every pure black one.” Abu Dawud and Darimi transmitted it. Tirmidhi and Nasai added, “No family attaches itself to a dog without a qirat of their good deeds being deducted daily, except in the case of a hunting dog, a farm dog, or a sheepdog.”
