932/1222 (Sahih) From Ibn Abbas who said: A mouse came and started dragging the wick, so the servant girl went to drive it away, but the Prophet, peace be upon him, said: "Leave it." Then it brought it and threw it onto the mat on which he was sitting, and it burned a spot the size of a dirham. The Messenger of Allah, peace be upon him, said: "When you go to sleep, extinguish your lamps, for Satan guides the likes of this (mouse) to the likes of this (wick) and burns you."
