المؤمنون — Al-Mu'minun Ayat 17
وَلَقَدْ خَلَقْنَا فَوْقَكُمْ سَبْعَ طَرَاۤىِٕقَۖ وَمَا كُنَّا عَنِ الْخَلْقِ غٰفِلِيْنَ
Wa laqad khalaqnā fauqakum sab‘a ṭarā'iq(a), wa mā kunnā ‘anil-khalqi gāfilīn(a).
"And We have created above you seven layered heavens, and never have We been of [Our] creation unaware."
