﴿ أَوَلَمْ يَرَوْا۟ إِلَى ٱلطَّيْرِ فَوْقَهُمْ صَٰٓفَّٰتٍۢ وَيَقْبِضْنَ ۚ مَا يُمْسِكُهُنَّ إِلَّا ٱلرَّحْمَٰنُ ۚ إِنَّهُۥ بِكُلِّ شَىْءٍۭ بَصِيرٌ ﴾

“Have they, then, never beheld the birds above them, spreading their wings and drawing them in? None but the Most Gracious upholds them: for, verily, He keeps all things in His sight.”

(Have they) i.e. the disbelievers of Mecca (not seen the birds above them) above their heads (spreading out their wings and closing them? Naught upholdeth them) after their spreading out (save the Beneficent. Lo! He is Seer of all things) whether it is spreading out or closing.
