Salim b. Abdullah reported on the authority of his father that Allah's Messenger said: Whosover amongst the owners of the house keeps a dog other than one meant for watching the herd or for hunting loses two qirat of his deeds every day.
حَدَّثَنَا دَاوُدُ بْنُ رُشَيْدٍ، حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، أَخْبَرَنَا عُمَرُ بْنُ حَمْزَةَ بْنِ عَبْدِ، اللَّهِ بْنِ عُمَرَ حَدَّثَنَا سَالِمُ بْنُ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَيُّمَا أَهْلِ دَارٍ اتَّخَذُوا كَلْبًا إِلاَّ كَلْبَ مَاشِيَةٍ أَوْ كَلْبَ صَائِدٍ نَقَصَ مِنْ عَمَلِهِمْ كُلَّ يَوْمٍ قِيرَاطَانِ" .
