That the Messenger of Allah ﷺ said: "Whoever keeps a dog" - or: "acquires a dog" - "neither of hunting nor to guard livestock, then two Qirat are deducted from his reward, daily."
قَالَ رَسُولُ اللَّهِ ﷺ مَنِ اقْتَنَى كَلْبًا لَيْسَ بِضَارٍ وَلاَ كَلْبَ مَاشِيَةٍ نَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطَانِ قَالَ وَفِي الْبَابِ عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ وَأَبِي هُرَيْرَةَ وَسُفْيَانَ بْنِ أَبِي زُهَيْرٍ
[Machine] From the Prophet ﷺ, that he said: "Whoever adopts or in other words, owns a dog that is neither harmful nor a dog used for herding, will have two good deeds deducted from his rewards every day." It was said to him: "What about Abu Hurairah's statement regarding a dog used for farming?" He replied, "There is still another good deed deducted."
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ مَنِ اتَّخَذَ أَوْ قَالَ اقْتَنَى كَلْبًا لَيْسَ بِضَارٍ وَلَا كَلْبَ مَاشِيَةٍ نَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطَانِ فَقِيلَ لَهُ إِنَّ أَبَا هُرَيْرَةَ يَقُولُ وَكَلْبَ حَرْثٍ؟ فَقَالَ أَنَّى
[Machine] I heard the Messenger of Allah ﷺ saying, "Whoever owns a dog, except for a dog used for herding animals or farming, will have two Qirats deducted from his reward every day." This narration is reported by Abdullah ibn Dinar in a Sahih Hadith from another source.
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنِ اقْتَنَى كَلْبًا إِلَّا كَلْبَ ضَارِيَةٍ أَوْ مَاشِيَةٍ نَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطَانِ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ وَجْهٍ آخَرَ عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ
