Sura Qāf 50:6

أَفَلَمْ يَنظُرُوٓا۟ إِلَى ٱلسَّمَآءِ فَوْقَهُمْ كَيْفَ بَنَيْنَٰهَا وَزَيَّنَّٰهَا وَمَا لَهَا مِن فُرُوجٍ

a-fa-lam yanẓurū ilā l-samāʾi fawqahum kayfa banaynāhā wa-zayyannāhā wa-mā lahā min furūjin

Do they not look at the sky above them?- How We have made it and adorned it, and there are no flaws in it?

Sura al-Dhāriyāt 51:47

وَٱلسَّمَآءَ بَنَيْنَٰهَا بِأَيْي۟دٍ وَإِنَّا لَمُوسِعُونَ

wa-l-samāʾa banaynāhā bi-ayydin wa-innā lamūsiʿūna

With power and skill did We construct the Firmament: for it is We Who create the vastness of pace.

Sura al-Nabaʾ 78:12

وَبَنَيْنَا فَوْقَكُمْ سَبْعًا شِدَادًا

wa-banaynā fawqakum sabʿan shidādan

And (have We not) built over you the seven firmaments,
