وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، وَابْنُ، نُمَيْرٍ قَالُوا حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَنِ اقْتَنَى كَلْبًا إِلاَّ كَلْبَ صَيْدٍ أَوْ مَاشِيَةٍ نَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطَانِ " .
Salim reported on the authority of his father that Allah's Apostle (ﷺ) said: He who kept a dog other than one meant for hunting or for watching the herd, lost two qirat of his reward every day.
