﴿ وَتَرَى ٱلْجِبَالَ تَحْسَبُهَا جَامِدَةًۭ وَهِىَ تَمُرُّ مَرَّ ٱلسَّحَابِ ۚ صُنْعَ ٱللَّهِ ٱلَّذِىٓ أَتْقَنَ كُلَّ شَىْءٍ ۚ إِنَّهُۥ خَبِيرٌۢ بِمَا تَفْعَلُونَ ﴾

“And thou wilt see the mountains, which [now] thou deemest so firm, pass away as clouds pass away: a work of God, who has ordered all things to per­fection! Verily, He is fully aware of all that you do!”

(And thou seest) O Muhammad upon the first blow of the trumpet (the hills thou deemest solid) and still (flying with the flight of clouds) in the air: (the doing of Allah) this is the doing of Allah with His creation (Who perfecteth all things) of creation. (Lo! He is Informed) Aware (of what ye do) of good or evil.
