It is narrated from Sayyiduna Abu Rafi’ (may Allah be pleased with him), who says: The Messenger of Allah (peace and blessings be upon him) ordered me to kill dogs, so I went out to kill them. Whenever I saw a dog, I would kill it. There was a dog circling around a house; when I was about to kill it, a person from inside the house called out to me and said: O servant of Allah! What do you intend to do? I said: I want to kill this dog. The woman said: I live in this wilderness (which is a cause of loss and destruction), and this dog wards off wild beasts from me, and because of it I get to know about those coming and going. Therefore, go to the Noble Prophet (peace and blessings be upon him) and inform him of this matter. So I went to the Noble Prophet (peace and blessings be upon him) and informed him of this, but he (peace and blessings be upon him) still ordered me to kill that dog.
