Ibn 'Abbas said, "A mouse came and began to drag the wick. The slavegirl moved to stop it. The Prophet, may Allah bless him and grant him peace, said, 'Leave it.' The mouse brought the wick and put it on the mat where he was sitting. It burned a hole in it the size of a dirham. The Messenger of Allah, may Allah bless him and grant him peace, said, 'When you go to sleep, put out the lights. Shaytan guides things like this and then they burn you.'"
