It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When there is nothing in front of the one praying as high as the back of a saddle, then a woman, a donkey, and a black dog break his prayer. Abdullah bin Samit said: What is the matter of specifying the black dog among the red dogs? He said: Nephew! Just as you asked me, I asked the Messenger of Allah (peace and blessings be upon him), so he (peace and blessings be upon him) said: The black dog is a devil.
