Muslim ibne-Harith At-Tamimi ( radi Allahu anhu ) narrates
that Rasulullah (Sallallahu Alaihi Wasallam) told him secretly:
When you complete the Maghrib Salat,
then recite seven times this Duua before speaking:
" Allahumma Ajirnee Minan Naar "
( O Allah protect me from the fire.)
If you die that night, Allah will write for you protection from the Fire.
When you have offered your Fajar Salat repeat
the same duua seven times before speaking:
" Allahumma Ajirnee Minan Naar "
( O Allah protect me from the fire.)
For undoubtedly, if you happen to die the
same day, you will be protected from the fire.
{ Abu Dawud, an-Nasa'i }
Note:- Rasulullah (Sallallahu Alaihi Wasallam)by giving
this advice secretly wanted to stress its importance.
