Surah Al-Furqan, ayah 59

ٱلَّذِي خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ وَمَا بَيۡنَهُمَا فِي سِتَّةِ أَيَّامٖ ثُمَّ ٱسۡتَوَىٰ عَلَى ٱلۡعَرۡشِۖ ٱلرَّحۡمَٰنُ فَسۡـَٔلۡ بِهِۦ خَبِيرٗا ٥٩

Alladhī khalaqas-samāwāti wal-arda wamā baynahumā fī sittati ayyāmin thummastawā 'alal-'arshir-rahmānu fas'al bihī khabīrā

He who created the heavens and the earth and what is between them in six days and then established Himself above the Throne¹⁰³⁴ - the Most Merciful, so ask about Him one well informed [i.e., the Prophet (ﷺ)].
