Wahuwa allathee khalaqa allayla wannahara washshamsa walqamara kullun fee falakin yasbahoon (surah Anbiya: 33)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(21:33) And it is Allah, Who has made the night and the day and created the sun and the moon; all of them are floating, each in its own orbit. *35

Wa Huwal lazee khalaqal laila wannahaara washshamsa wal qamara kullun fee falakiny yashbahoon

*35) The use of the words kullun (alI) and yasbahun (float) in the plural (for more than two) indicates that not only the sun and the moon but all the heavenly bodies are floating in their own separate orbits and none of them is fixed or stationary. These verses (30-33) are capable of being interpreted in the modern scientific terms in accordance with the present day conceptions of Physics, Biology and Astronomy.
Here it should also be noted that vv. 19-23 refute shirk while vv. 30-33 present positive proofs of Tauhid. They imply that the creation and regular functioning of the universe clearly show that it is the work of One All-Powerful Creator, and no sensible person can say that it has been created as a there pastime for the sake of fun. When the fact is this and you see proofs of the Doctrine of Tauhid all around yourself, in the earth and heavens, why do you reject the Message of the Prophet and demand other Signs from him ?
