Prophet Muhammad (S.A.W.) has said that on the day of judgement
there will be some people who will have to go to Jahannam (Hell)
because of their bad deeds.
However, from these people, there will be some who had the habit of saying Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful)
before they did anything or entered anywhere.
Thus, when they will be taken to Jahannam (Hell) by the angels, they will be
very sad but they will say Bismillahirrahmanirrahim
(In the name of Allah, the beneficent the merciful) Allah will tell the angels -
"STOP" Allah will tell them that He cannot let someone who says
Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful)
calling Him Rahman and Rahim enter Jahannam (Hell).
