Abdullah bin Samit narrates from Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) said: "A woman, a donkey, and a black dog (passing in front of a person praying) break the prayer." The narrator says: I asked, "O (Sayyiduna) Abu Dharr (may Allah be pleased with him)! Why a black dog, why not a red or yellow one?" He replied: "I asked the Prophet Muhammad (peace and blessings be upon him) the same question that you have asked me, and the Prophet Muhammad (peace and blessings be upon him) said: 'The black (dog) is a devil.'"
