فَقَضاهُنَّ سَبعَ سَماواتٍ في يَومَينِ وَأَوحىٰ في كُلِّ سَماءٍ أَمرَها ۚ وَزَيَّنَّا السَّماءَ الدُّنيا بِمَصابيحَ وَحِفظًا ۚ ذٰلِكَ تَقديرُ العَزيزِ العَليمِ

Thus, He completed them as seven heavens in two periods, and He assigned to each heaven its duty. We adorned the nearest heaven with lamps and protection. Such is the decree of the Almighty, the All-Knowing.
