And you see the mountains, thinking them rigid, while they will pass (27:88)

﴿وَتَرَى الْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِيَ تَمُرُّ مَرَّ السَّحَابِ ۚ صُنْعَ اللَّهِ الَّذِي أَتْقَنَ كُلَّ شَيْءٍ ۚ إِنَّهُ خَبِيرٌ بِمَا تَفْعَلُونَ﴾
[ النمل: 88]

27:88 And you see the mountains, thinking them rigid, while they will pass as the passing of clouds. [It is] the work of Allah, who perfected all things. Indeed, He is Acquainted with that which you do.

And you will see mountains on that day thinking them to be firm without moving, but they will in fact move like clouds move.
It is the doing of Allah, for He is the one who makes them move.
He is Aware of what you do.
None of your actions are hidden from Him and He shall reward you for them.

And you will see the mountains and think them solid, but they shall pass away as the passing away of the clouds. The Work of Allah, Who perfected all things, verily! He is Well-Acquainted with what you do.

Thou seest the mountains and thinkest them firmly fixed: but they shall pass away as the clouds pass away: (such is) the artistry of Allah, who disposes of all things in perfect order: for he is well acquainted with all that ye do.
