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). Ya-Sin 36:40 ⧉
Tafsir:
The earth, the moon and the sun have their fixed orbits, in which they move with the utmost precision, and due to which different celestial phenomena take place: for instance, the occurrence of day and night on the earth and the waxing and waning of the moon, serve as a heavenly calendar. This system has been in existence for millions of years now, and there is still no deviation of any kind in it. This observation is purely an introduction to the fathomless and unlimited powers of God. If man learns lessons from these phenomena, the majesty of the One God will prevail over his mind to such an extent that all other impressions of greatness will be automatically erased from it.
