The striking calamity:
What is the striking calamity?
And how would you know what is the striking calamity?
It is the Day when the human beings will be like dispersed moths
and the mountains will be like fluffed up wool
and then, the one whose scales are heavy [with good deeds]
will have a pleasant life,
but the one whose scales are light,
his refuge will be an abyss.
And what will convey to you what that is?
a Raging Fire
