Translation of the verse 12 from Surah Fussilat : Number of verses 54 - - page 478 - Part 24.
Then He completed and finished from their creation (as) seven heavens in two Days and He made in each heaven its affair. And We adorned the nearest (lowest) heaven with lamps (stars) to be an adornment as well as to guard (from the devils by using them as missiles against the devils). Such is the Decree of Him the All-Mighty, the All-Knower.
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.
(41:12) Then He made them seven heavens in two days and revealed to each heaven its law. And We adorned the lower heaven with lamps, and firmly secured it. *16 All this is the firm plan of the All-Mighty, the All-Knowing.
