Keep your children indoors at nightfall
Sayyiduna Jaabir Bin Abdullah Radhiyallahu Anhu narrates that Rasulullah Sallallahu Alayhi Wasallam said: “When night falls – or it is evening, restrain your children (from going out) as the devils spread out at that time. But when an hour of the night elapses, then you may let them free.
Close the doors and mention the Name of Allah, for the devil does not open a closed door; and tighten the (mouths of) water skins and mention the name of Allah; and cover your utensils and mention the name of Allah even if you just place something over them; and put off your lights.” (Bukhari)
