Etiquette of retiring for the night — context

When night falls (i.e. 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 Allah’s name, for verily the devil does not open a shut door, tie up your water-skins and mention Allah’s name, cover your vessels with anything and mention Allah’s name and put out your lamps.
