“The prayer is severed by a woman, a donkey, and a
black dog, if there is not something like the handle of a saddle in
front of a man.” I (‘Abdullah) said: “What is wrong with a
black dog
and not a red one?” He (Abu Dharr) said: ‘I asked the
Messenger of
Allah (ﷺ) the same question, and he said: “The black
dog is a
Shaitan (satan).”
