Surah Nuh 71:16

وَجَعَلَ ٱلْقَمَرَ فِيهِنَّ نُورًا وَجَعَلَ ٱلشَّمْسَ سِرَاجًا

And made the moon therein a [reflected] light and made the sun a burning lamp?

Translation: Saheeh International

Tafsir

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.
