Yahya related to me from Malik from Abuz-Zubayr al-Makki from Jabir ibn Abdullah that the Messenger of Allah, may Allah bless him and grant him peace, said, "Lock the door, tie the waterskin, turn the vessel over or cover it, and put out the lamp. Shaytan does not open a locked door or untie a tied knot, or uncover a vessel. A mouse may set fire to peoples houses about them."
