Question:
I have read once that one should close doors before going to sleep to avoid the shaiytaan from entering into the house. I heard from my parents that one should close all doors, windows and curtains before magrib to prevent shaitaans entry.

Answer:
Keep children indoors at magrib time  (Bukhari Shareef). Read Bismilla and close doors etc before sleeping. It is not compulsory to close doors and windows at magrib trime.
