فَقَضَىٰهُنَّ Then He completed them سَبْعَ (as) seven سَمَـٰوَاتٍۢ heavens فِى in يَوْمَيْنِ two periods وَأَوْحَىٰ and He revealed فِى in كُلِّ each سَمَآءٍ heaven أَمْرَهَا ۚ its affair وَزَيَّنَّا And We adorned ٱلسَّمَآءَ the heaven ٱلدُّنْيَا [the world] بِمَصَـٰبِيحَ with lamps وَحِفْظًۭا ۚ and (to) guard ذَٰلِكَ That تَقْدِيرُ (is the) Decree ٱلْعَزِيزِ (of) the All-Mighty ٱلْعَلِيمِ the All-Knower ١٢
And He completed them as seven heavens within two days and inspired [i.e., made known] in each heaven its command. And We adorned the nearest heaven with lamps [i.e., stars, for beauty] and as protection. That is the determination of the Exalted in Might, the Knowing.
