Some commentators of the Qur’an...
Some commentators of the Qur’an, such as the Late Tabarsi in “Majma‘-ul-Bayan” and ’Alusi in “Ruh-ul-Bayan”, have interpreted the word ‘Salat’, mentioned here, as supplication, which is its main concept in dictionary. Thus, the creatures of heaven and earth pray Allah with gestures or with their own verbal language and ask Him grace and He, Who is absolutely gracious, bestows it on them, according to their potentialities, as they deserve.
But they primitively know what they need and what they must ask for and what kind of supplication they ought to pray. Moreover, according to aforementioned verses, they are humble before His magnificent court and yield to the rules of creation. On the other hand they declare Allah’s attributes of perfection with their whole entity and negate any shortcoming about Him. Thus, their four worships are completed by: praising, glorification, prayer, and prostration.
And He sends down from the heaven from the (clouds like) mountains wherein is hail, afflicting therewith whom He pleases, and turning it away from whom He pleases. The flash of its lightning well-nigh blinds the sight.” To study creation is the best way for knowing Allah which causes to have His love. All movements in the universe are done with Divine will and power and also for a wise aim.
Therefore, in this verse, we face a little part of the wonders of creation, and the science, wisdom and magnificence that are behind them. All of them are reasons of His Pure Essence and monotheism.
So the Qur’an, addressing the Prophet (S), says: “Have you not seen that Allah drives gently the clouds, then joins them together, then converts them into a mass, and you see the rain coming forth from the midst of them?...” The Arabic word /yuzji/ is derived from the word /’izja’/ which means ‘to drive softly’. It is the driving that is used for arranging the scattered creatures, and this word is exactly true about clouds.
