وَتَرَى ٱلْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِىَ تَمُرُّ مَرَّ ٱلسَّحَابِ ۚ صُنْعَ ٱللَّهِ ٱلَّذِىٓ أَتْقَنَ كُلَّ شَىْءٍ ۚ إِنَّهُۥ خَبِيرٌۢ بِمَا تَفْعَلُونَ
You will see the mountains, thinking them firmly fixed[28], but they will be moving like clouds – such is the design of Allah, Who has perfected everything. Indeed, He is All-Aware of what 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.
