Assalamu'Alaykum

Yes also when i heard this it was amusing to me, see what happens is that once someone dies with the shadah (inshallah we will die with the shadah) The angles Munkir and Nakir will come and ask us Who is your lord : sometimes from the fear and shock that we will get we will not be able to answer and they will hit you till u go down 7 hells. then u will say Laillah illaah.... they will do this 3 times and if u fail to give the right answer which is Allah. you will be punished. But if you get it then they will leave and Basheer and Mubasher will coome and show you ur final abode.

this hadith is in Muslim and Bukhari.... (inshallah i will try to look for it.)

I ask Allah to forgive me if i have mistranslated.
And if anyone knowsabout this plz correct me
