Sura al-Anbiyāʾ 21:33

وَهُوَ ٱلَّذِى خَلَقَ ٱلَّيْلَ وَٱلنَّهَارَ وَٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّ فِى فَلَكٍ يَسْبَحُونَ

wa-huwa alladhī khalaqa l-layla wa-l-nahāra wa-l-shamsa wa-l-qamara kullun fī falakin yasbaḥūna

It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course.

Sura Yā Sin 36:40

لَا ٱلشَّمْسُ يَنۢبَغِى لَهَآ أَن تُدْرِكَ ٱلْقَمَرَ وَلَا ٱلَّيْلُ سَابِقُ ٱلنَّهَارِ وَكُلٌّ فِى فَلَكٍ يَسْبَحُونَ

lā l-shamsu yanbaghī lahā an tudrika l-qamara wa-lā l-laylu sābiqu l-nahāri wa-kullun fī falakin yasbaḥūna

It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law).
