It is narrated from Sayyiduna Abdullah bin Mughaffal Muzani (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: If dogs were not a community (ummah) among the communities, I would have ordered their extermination. Therefore, kill every jet-black dog. And whoever keeps a dog that is not for guarding fields, hunting, or livestock, their reward will be reduced by one qirat every day. And we were commanded that we may pray in sheep enclosures, but not in camel enclosures, because their creation is from Satan (there is a satanic nature in them).
