It was narrated from ‘Abdullah bin Mughaffal that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “Were it not that dogs form one of the communities (or nations — of creatures), I would have commanded that they be killed. But kill those that are all black. Any people who keep a dog, except for dogs used for farming, hunting or herding livestock, one Qirat will be deducted from their reward each day.” (Hasan)
