Quran 50:6 from Surah Qaaf on Divine Marvels.
أَفَلَمۡ يَنظُرُوٓاْ إِلَى ٱلسَّمَآءِ فَوۡقَهُمۡ كَيۡفَ بَنَيۡنَٰهَا وَزَيَّنَّٰهَا وَمَا لَهَا مِن فُرُوجٖ
English translation: Then do not they look at the sky above them how We structured it and adorned it and not for it any rifts
Transliteration: afalam yanzuru ila al-samai fawqahum kayfa banaynaha wazayyannaha wama laha min furujin
