وَالشَّمْسُ تَجْرِي لِمُسْتَقَرٍّ لَّهَا ذَلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ
The sun runs on to its place of rest: That is the ordaining of the All-mighty, the All-knowing.
Agha Ali Puya Commentary
Commentary on Quran 36:38
[Pooya/Ali Commentary 36:38] The sun runs its course in daily rotation as well as annual revolution. It was supposed that the sun was stationary, but now it has been found out that it is also rotating, travelling towards a fixed destination or an end, and no one knows when it would cease to function. This is the decree of the omnipotent Lord. See Rad : 2; Anbiya :33.
