Not allowing your children outdoors till an hour of the night has passed(i.e. do not leave them out close to Maghrib)
Narrated Jabir bin `Abdullah:
Allah’s Messenger (ﷺ) said, “When night falls (or it is evening), keep your children close to you for the devils spread out at that time. But when an hour of the night elapses, you can let them free. Close the doors and mention the Name of Allah, for Satan does not open a closed door.”
(Sahih Al-Bukhari,3304)
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. “
(Sahih Al-Bukhari, 5623)
Muslim (2013) also narrated from Jaabir (may Allaah be pleased with him) that he said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Do not let your animals and children go out when the sun has set, until the first part of the night is over, for the devils come out when the sun sets, until the first part of the night is over.”
