Surah Al-Furqan, Verse 59

ٱلَّذِي خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ وَمَا بَيۡنَهُمَا فِي سِتَّةِ أَيَّامٖ ثُمَّ ٱسۡتَوَىٰ عَلَى ٱلۡعَرۡشِۖ ٱلرَّحۡمَٰنُ فَسۡـَٔلۡ بِهِۦ خَبِيرٗا٥٩

alladhī khalaqa l-samāwāti wal-arḍa wamā baynahumā fī sittati ayyāmin thumma is'tawā ʿalā l-ʿarshi l-raḥmānu fasal bihi khabīran

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