وعن أبي هريرة رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : "من أمسك كلبًا فإنه ينقص كل يوم من عمله قيراط إلا كلب حرث أو ماشية" ((متفق عليه)). وفي رواية لمسلم: "من اقتنى كلبًا ليس بكلب صيد، ولا ماشية ولا أرض، فإنه ينقص من أجره قيراطان كل يوم".
The Messenger of Allah (ﷺ) said, "He who keeps a dog, will lose out of his good deeds equal to one Qirat every day, except one who keeps it for guarding the fields or the herd."[Al-Bukhari and Muslim].In a narration of Muslim, the Messenger of Allah (ﷺ) is reported to have said: "He who keeps a dog for any reason other than to guard his property (lands) or his flock of sheep, his good deeds equal to two Qirat will be deducted every day."
