Al-Qamar (The Moon)

50. And Our Commandment is but a fast one as the twinkling of an eye.

51. And verily, We caused the perdition of your likes; then is there anyone who will receive admonition?

Divine Acts are carried out Well-Measured, Wise, and Fast. Thus the blessed Verse 50 is saying that Divine Command is but One and it is done as fast as the twinkling of an eye. Whatever He wills, He merely says "Be" and it will come into being. Even the Arabic imperative form "kun" ("be") is employed due to linguistic restrictions of human language; otherwise, Divine Will is on a par with the realization of His Will. Thus, We God Almighty issues the Command as to Resurrection, everything will be resurrected in the twinkling of an eye and new life shall be given to bodies.

Likewise, on that Day, when God Almighty wills to chastise sinners by lightning, loud cries heard from the heaven, earthquake, tempests, and harsh gales, solely one single Command shall suffices to realize everything. They all serve as Warnings to sinners that they know that God Almighty is All-Wise and His Wills are decisive so that they may be aware of the evil consequences of disobeying His Commands.

The blessed Verse 51 addresses sinners and disbelievers once more and draws their attention to the fate of ancient peoples saying that God Almighty caused the perdition of peoples who were like you aforetime. Is there anyone who will remember and receive admonition, namely awakens and takes a lesson?
