سنن أبي داود

Abu Hurairah reported the Messenger of Allah(ﷺ) as saying “There are Camels which belong to devils and there are houses which belong to devils. As for the Camels of the devils, I have seen them. One of you goes out with his side Camels which he has fattened neither riding any of them nor giving a lift to a tired brother when he meets. As regard the houses of the devils, I have not seen them. The narrator Sa’id says “I think they are those cages (Camel litters) which conceal people with brocade.”
