Adh-Dhaariyat (The Winnowing Winds)

5. Indeed, that which you are promised is certainly true.

6. And indeed, the [Day of] Recompense is certain to occur.

God Almighty fulfills the Promises given to His servants in this world and the Hereafter. God Almighty whose Manifestations of Omnipotence are visible in the world of creation is Able to fulfill His Promises.

The twain blessed Verses in question serve as the apodoses of the oaths to such multiplicities in the natural phenomena and their distribution as promised by the Prophets including the Rewards, Chastisements, Paradise, and Hell which are all true. Since the oath taken is supposed to be consistent with what is mentioned as the substantiation thereof, making mention of the multiplicities of the natural phenomena, e.g. wind, rain, and cloud, may make a reference to the point that despite the contradiction and dispersion of natural phenomena, God Almighty has removed such contradiction and dispersion though His Omniscience and Omnipotence and they all constitute an orderly world.

Likewise, it was promised by the Prophets as to getting together of all mankind and jinn living in dispersion and different spatial and temporal spheres that on the Promised Day they shall get together in one single line. These temporally disintegrated creatures shall unite on the Day of Resurrection. Thus, all different and dispersed deeds committed in this world shall be presented to them in the Books of Deeds and those committing them shall be recompensed.
