Have they not looked at the heaven above them - how We structured it and adorned it and [how] it has no rifts?
The Saheeh International Quran Translation
أَفَلَمْ يَنظُرُوٓا۟ إِلَى ٱلسَّمَآءِ فَوْقَهُمْ كَيْفَ بَنَيْنَٰهَا وَزَيَّنَّٰهَا وَمَا لَهَا مِن فُرُوجٍHave they not looked at the heaven above them - how We structured it and adorned it and [how] it has no rifts?
