وَجَعَلَ فِيهَا رَوَٰسِيَ مِن فَوۡقِهَا وَبَٰرَكَ فِيهَا وَقَدَّرَ فِيهَآ أَقۡوَٰتَهَا فِيٓ أَرۡبَعَةِ أَيَّامٖ سَوَآءٗ لِّلسَّآئِلِينَ
He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four Days equal (i.e. all these four 'days' were equal in the length of time), for all those who ask (about its creation).
ثُمَّ ٱسۡتَوَىٰٓ إِلَى ٱلسَّمَآءِ وَهِيَ دُخَانٞ فَقَالَ لَهَا وَلِلۡأَرۡضِ ٱئۡتِيَا طَوۡعًا أَوۡ كَرۡهٗا قَالَتَآ أَتَيۡنَا طَآئِعِينَ
Then He Istawa (rose over) towards the heaven when it was smoke, and said to it and to the earth: "Come both of you willingly or unwillingly." They both said: "We come, willingly."
فَقَضَىٰهُنَّ سَبۡعَ سَمَٰوَاتٖ فِي يَوۡمَيۡنِ وَأَوۡحَىٰ فِي كُلِّ سَمَآءٍ أَمۡرَهَاۚ وَزَيَّنَّا ٱلسَّمَآءَ ٱلدُّنۡيَا بِمَصَٰبِيحَ وَحِفۡظٗاۚ ذَٰلِكَ تَقۡدِيرُ ٱلۡعَزِيزِ ٱلۡعَلِيمِ
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.
فَإِنۡ أَعۡرَضُواْ فَقُلۡ أَنذَرۡتُكُمۡ صَٰعِقَةٗ مِّثۡلَ صَٰعِقَةِ عَادٖ وَثَمُودَ
But if they turn away, then say (O Muhammad SAW): "I have warned you of a Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) like the Sa'iqah which overtook 'Ad and Thamud (people)."
