فَقَضٰىهُنَّ سَبْعَ سَمٰوَاتٍ فِيْ يَوْمَيْنِ وَاَوْحٰى فِيْ كُلِّ سَمَاۤءٍ اَمْرَهَا ۗوَزَيَّنَّا السَّمَاۤءَ الدُّنْيَا بِمَصَابِيْحَۖ وَحِفْظًا ۗذٰلِكَ تَقْدِيْرُ الْعَزِيْزِ الْعَلِيْمِ
Fa qaḍāhunna sab‘a samāwātin fī yaumaini wa auḥā fī kulli samā'in amrahā, wa zayyannas-samā'ad-dun-yā bimaṣābīḥa wa ḥifẓā(n), żālika taqdīrul-‘azīzil-‘alīm(i).
"And He completed them as seven heavens within two days and inspired in each heaven its command. And We adorned the nearest heaven with lamps and as protection. That is the determination of the Exalted in Might, the Knowing."
