The sun and the moon appear here as two signs of the Creator, made subservient to mankind for an appointed term. The verses describe each swimming in an orbit and serving to reckon time, the one giving radiance and the other light, and see in the impossibility of altering their course a proof of the Creator; they also mention Joseph’s dream and the People of the Cave.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
[He is] the cleaver of daybreak and has made the night for rest and the sun and moon for calculation. That is the determination of the Exalted in Might, the Knowing.
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.
