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

“He who has created the heavens and the earth and all that is between them in six aeons, and is established on the throne of His almightiness: the Most Gracious! Ask, then, about Him, [the] One who is [truly] aware.”
