فَقَضَىٰهُنَّ سَبْعَ سَمَٰوَاتٍۢ فِى يَوْمَيْنِ وَأَوْحَىٰ فِى كُلِّ سَمَآءٍ أَمْرَهَا ۚ وَزَيَّنَّا ٱلسَّمَآءَ ٱلدُّنْيَا بِمَصَٰبِيحَ وَحِفْظًۭا ۚ ذَٰلِكَ تَقْدِيرُ ٱلْعَزِيزِ ٱلْعَلِيمِ
Then He ordained them seven heavens in two Days and inspired in each heaven its mandate; and We decked the nether heaven with lamps, and rendered it inviolable. That is the measuring of the Mighty, the Knower.
