حَدَّثَنَا عَبْد اللَّهِ قَالَ وَجَدْتُ فِي كِتَابِ أَبِي حَدَّثَنَا ابْنُ نُمَيْرٍ عَنْ حَنْظَلَةَ عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ عَنِ ابْنِ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ اقْتَنَى كَلْبًا إِلَّا ضَارِيًا أَوْ كَلْبَ مَاشِيَةٍ فَإِنَّهُ يَنْقُصُ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطَانِ
مسند امام احمد بن حنبل · Hadith 5073
It was narrated that Ibn 'Umar said: The Messenger of Allah (PBUH) said: "Whoever keeps a dog, except a trained dog for hunting or for herding livestock, two qiraats will be deducted from his reward each day."
