Abdullah bin Samit reports that Sayyiduna Abu Dharr (may Allah be pleased with him) said: A donkey, a woman, and a black dog break the prayer. I asked, "O Abu Dharr, what is the distinction of a black dog over a white, yellow, or red dog (that the prayer is broken by it and not by the others passing)?" He replied, "My nephew, I asked the Messenger of Allah (peace and blessings be upon him) just as you have asked me, and he (peace and blessings be upon him) said: 'The black dog is a devil.'"
