﴿ وَجَعَلَ ٱلْقَمَرَ فِيهِنَّ نُورًۭا وَجَعَلَ ٱلشَّمْسَ سِرَاجًۭا ﴾

“and has set up within them the moon as a light [reflected] and set up the sun as a [radiant] lamp?”

and made the moon therein — that is to say within their totality but which is effectively true in the case of the heaven of this world — as a light and made the sun as a lamp? as an illuminating lantern more powerful than the light of the moon.
