Surat An-Naml (The Ant) - النمل

وَتَرَى ٱلْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِىَ تَمُرُّ مَرَّ ٱلسَّحَابِ صُنْعَ ٱللَّهِ ٱلَّذِىٓ أَتْقَنَ كُلَّ شَىْءٍ إِنَّهُۥ خَبِيرٌۢ بِمَا تَفْعَلُونَ ﴿٨٨﴾

And you see the mountains, you think them to be solid, and they shall pass away as the passing away of the cloud-- the handiwork of Allah Who has made every thing thoroughly; surely He is Aware of what you do.
