"Were it not that dogs form one of the communities (or nations - of creatures), I would have commanded that they be killed. But kill those that are all black. Any people who keep a dog, except for dogs used for farming, hunting or herding livestock, one Qirat will be deducted from their reward each day." (Using translation from Nasāʾī 4280)  

قَالَ رَسُولُ اللهِ ﷺ «لَوْلَا أَنَّ الْكِلَابَ أُمَّةٌ مِنَ الْأُمَمِ لَأَمَرْتُ بِقَتْلِهَا فَاقْتُلُوا مِنْهَا الْأَسْوَدَ الْبَهِيمَ وَأَيُّمَا قَوْمٍ اتَّخَذُوا كَلْبًا لَيْسَ بِكَلْبِ حَرْثٍ أَوْ صَيْدٍ أَوْ مَاشِيَةٍ فَإِنَّهُ يَنْقُصُ مِنْ أَجْرِهِمْ كُلَّ يَوْمٍ قِيرَاطٌ»
