"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."  

قَالَ رَسُولُ اللَّهِ ﷺ لَوْلاَ أَنَّ الْكِلاَبَ أُمَّةٌ مِنَ الأُمَمِ لأَمَرْتُ بِقَتْلِهَا فَاقْتُلُوا مِنْهَا الأَسْوَدَ الْبَهِيمَ وَأَيُّمَا قَوْمٍ اتَّخَذُوا كَلْبًا لَيْسَ بِكَلْبِ حَرْثٍ أَوْ صَيْدٍ أَوْ مَاشِيَةٍ فَإِنَّهُ يَنْقُصُ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطٌ
