Surah Yunus, ayah 5

10:5

هُوَ ٱلَّذِي جَعَلَ ٱلشَّمۡسَ ضِيَآءٗ وَٱلۡقَمَرَ نُورٗا وَقَدَّرَهُۥ مَنَازِلَ لِتَعۡلَمُواْ عَدَدَ ٱلسِّنِينَ وَٱلۡحِسَابَۚ مَا خَلَقَ ٱللَّهُ ذَٰلِكَ إِلَّا بِٱلۡحَقِّۚ يُفَصِّلُ ٱلۡأٓيَٰتِ لِقَوۡمٖ يَعۡلَمُونَ ٥

Huwal-ladhī ja'alash-shamsa diyā'an wal-qamara nūran waqaddarahū manāzila lita'lamū 'adadas-sinīna wal-hisāba mā khalaqallāhu dhālika illā bil-haqqi yufassilul-āyāti liqawmin ya'lamūn

It is He who made the sun a shining light and the moon a derived light and determined for it phases - that you may know the number of years and account [of time]. Allāh has not created this except in truth. He details the signs for a people who know.
