Surah Al-Qariah  (The Smiter)
What is the Calamity?
Ah, what will convey unto thee what the Calamity is
A day wherein mankind will be as thickly-scattered moths
And the mountains will become as carded wool.
Then, as for him whose scales are heavy (with good works), He will live a pleasant life.
But as for him whose scales are light,
A bereft and Hungry One will be his mother, Ah, what will convey unto thee what she is! - Raging Fire.
