Sayyiduna Abu Hurayrah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "There are camels and houses that belong to the devils too."
(1) "As for the camels of the devils, I have seen them: one of you sets out with fine camels which are fat and well-fed, yet he does not ride any of them, and he passes by his brother whose mount has given out, and he does not give him a ride. As for the houses of the devils, I have not seen them." Sa'id says: I think they are these cages (litters) which people cover with silk curtains.
