وَتَرَى الْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِيَ تَمُرُّ مَرَّ السَّحَابِ صُنْعَ اللَّهِ الَّذِي أَتْقَنَ كُلَّ شَيْءٍ إِنَّهُ خَبِيرٌ بِمَا تَفْعَلُونَ
You see the mountains, which you suppose, to be stationary, while they drift like passing clouds—the handiwork of Allah who has made everything faultless. He is indeed well aware of what you do.
