Narrated Jabir bin `Abdullah
Allah's Messenger (ﷺ) said, "When night falls (or when it is evening), stop your children from going out, for the devils spread out at that time. But when an hour of the night has passed, release them and close the doors and mention Allah's Name, for Satan does not open a closed door. Tie the mouth of your waterskin and mention Allah's Name; cover your containers and utensils and mention Allah's Name. Cover them even by placing something across it, and extinguish your lamps. "
Narrated Jabir
Allah's Messenger (ﷺ) said, "Extinguish the lamps when you go to bed; close your doors; tie the mouths of your water skins, and cover the food and drinks." I think he added, "... even with a stick you place across the container."
