Etiquette of retiring for the night

When night falls [i.e., at al-Maghrib] , restrain your children [from going out] because at such time the devils spread about. After a period of time has passed, let them be. Shut your doors and mention Allaah"s name, for verily the devil does not open a shut door, tie up your water-skins and mention Allaah"s name, cover your vessels with anything and mention Allaah"s name and put out your lamps.'

Al-Bukhari, Muslim 3/1595.
