question #2 Sahih al-Bukhari 3304, Book 59, Hadith 112 : Why is it important to mention the Name of Allah when closing doors at night?

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.”
