Had there been within the heavens and earth gods besides Allah, they (21:22)

Almuntakhab Fi Tafsir Alquran Alkarim

Indeed, if there be Ilahs other than Allah or sharing His divine nature and attributes, the heavens and the earth would have become corrupt and been ruined. Therefore, praise be to Allah and extolled are His glorious attributes the sole Sovereign of the Supreme Throne. He is far above what they ascribe to Him

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

(21:22) Had there been other deities besides Allah in the heavens and the earth, both (the heavens and the earth) would have gone out of order. *22 So, absolutely free is Allah, Lord of the Throne, *23 from the false things they ascribe to Him.

Had there been within the heavens and earth gods besides Allah, they meaning

*22) This concise sentence contains two arguments:
(1) The obviously simple argument is that no institution, no household, not to speak of the vast universe containing multitudes of countless distant stars, can function smoothly and properly, if it has two masters.
(2) The deeper argument is that the system of the whole universe, including that of the earth, is functioning according to a universal law. It could not work so even for a moment, if there had been no proper proportion, balance, harmony and coordination between the different powers and countless things. This is a clear proof that there is a universal and all-powerful law and system which binds and forces these powers and things tc co-operate and coordinate between themselves with a perfect proportion and harmony and this could not have happened if there had been different independent rulers. The existence of such a system is itself a clear proof that there must be One All-Powerful Manager and Administrator governing and ruling the whole universe. For further details, please see E. N. 47 of Bani Isra'il (XVII).
*23) That is, "The Sovereign of the whole universe."
