Jabir ibn 'Abdullah reported that the Messenger of Allah, may
Allah bless him and grant him peace, said, "Lock the doors, tie the water-skins,
turn over the vessels, cover the vessels, and put out the lamps. Shaytan
does not open a locked door, nor untie a water-skin, nor uncover a vessel.
A mouse can cause a house to burn down with its inhabitants inside it."
