The Prophet ﷺ as saying: If anyone gets a dog, except a sheeping or hunting or a farm dog, a qirat of his reward will be deducted daily. (Using translation from Abū Dāʾūd 2844)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنِ اتَّخَذَ كَلْبًا إِلَّا كَلْبَ صَيْدٍ أَوْ مَاشِيَةٍ أَوْ زَرْعٍ نَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطٌ»  

"Whoever keep s dog except a dog for hunting, farming or herding livestock, on e Qurat will be deducted from his good deeds each day." (Using translation from Nasāʾī 4289)  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «مَنِ اتَّخَذَ كَلْبًا إِلَّا كَلْبَ صَيْدٍ أَوْ زَرْعٍ أَوْ مَاشِيَةٍ نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطٌ»  

"Whoever keeps a dog that is not a dog used for hunting, herding livestock or guarding land, two qirats will be deducted from his reward each day." (Using translation from Nasāʾī 4290)  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «مَنِ اقْتَنَى كَلْبًا لَيْسَ بِكَلْبِ صَيْدٍ وَلَا مَاشِيَةٍ وَلَا أَرْضٍ فَإِنَّهُ يَنْتَقِصُ مِنْ أَجْرِهِ قِيرَاطَيْنِ كُلَّ يَوْمٍ»  

He who kept a dog other than one meant for watching the herd or for hunting would lose every day two qirat of his good deeds. 'Abdullah and Abu Huraira also said: Or dog meant for watching the field. (Using translation from Muslim 1574d)  

أَنَّ رَسُولُ اللهِ ﷺ قَالَ «مَنِ اقْتَنَى كَلْبًا إِلَّا كَلْبَ مَاشِيَةٍ أَوْ كَلْبَ صَيْدٍ نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطٌ» قَالَ عَبْدُ اللهِ وَقَالَ أَبُو هُرَيْرَةَ أَوْ كَلْبَ حَرْثٍ
