Narrated by Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: If dogs were not a community among various communities, I would have ordered them all to be killed completely. Now, you should kill every black one among them.

Brief Explanation
Benefits: … The purpose of this statement of the Noble Prophet (sallallahu alayhi wa sallam) is that Allah Ta’ala has placed some wisdom and benefit in the creation of each of His creatures; therefore, it is not appropriate to wipe out an entire species from existence. However, among them, the mischievous type of dogs, those that are jet black in color, should be killed, and the rest should not be killed.
