Surah Qaf, Verse 6

أَفَلَمۡ يَنظُرُوٓاْ إِلَى ٱلسَّمَآءِ فَوۡقَهُمۡ كَيۡفَ بَنَيۡنَٰهَا وَزَيَّنَّٰهَا وَمَا لَهَا مِن فُرُوجٖ٦

afalam yanẓurū ilā l-samāi fawqahum kayfa banaynāhā wazayyannāhā wamā lahā min furūjin

Have they not looked at the heaven above them - how We structured it and adorned it and [how] it has no rifts?
