Al-Qari'ah 101:7

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.

فَأَمَّا مَن ثَقُلَتْ مَوَازِينُهُ

Then as for one whose scales are heavy [with good deeds],

وَأَمَّا مَنْ خَفَّتْ مَوَازِينُهُ

But as for one whose scales are light,

فَأُمُّهُ هَاوِيَةٌ

His refuge will be an abyss.

وَمَا أَدْرَاكَ مَا هِيَهْ

And what can make you know what that is?
