Al-Qari'ah 101:2

بِسْمِ اللَّهِ الرَّحْمَـٰنِ الرَّحِيمِ الْقَارِعَةُ

The Striking Calamity -

وَمَا أَدْرَاكَ مَا الْقَارِعَةُ

And what can make you know what is the Striking Calamity?

يَوْمَ يَكُونُ النَّاسُ كَالْفَرَاشِ الْمَبْثُوثِ

It is the Day when people will be like moths, dispersed,

وَتَكُونُ الْجِبَالُ كَالْعِهْنِ الْمَنفُوشِ

And the mountains will be like wool, fluffed up.
