Al-Furqan 25:59

ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَمَا بَيْنَهُمَا فِى سِتَّةِ أَيَّامٍۢ ثُمَّ ٱسْتَوَىٰ عَلَى ٱلْعَرْشِ ۚ ٱلرَّحْمَٰنُ فَسْـَٔلْ بِهِۦ خَبِيرًۭا

He Who created the heavens and the earth and all that is between, in six days, and is firmly established on the Throne (of Authority): Allah Most Gracious: ask thou, then, about Him of any acquainted (with such things).
