Translation of the verse 17 from Surah Ghafir : Number of verses 85 - - page 469 - Part 24.
This Day shall every person be recompensed for what he earned. No injustice (shall be done to anybody). Truly, Allah is Swift in reckoning.
This Day every soul will be recompensed for what it earned. No injustice today! Indeed, Allah is swift in account.
(40:17) (It will then be said): 'Today shall everyone be fully recompensed for his deeds. None shall be wronged today. *28 Surely Allah is Swift in Reckoning.' *29
*28) That is, "None shall be wronged in any way whatever today." It should be noted that in respect of recompense, injustice can have several forms; ( 1) A person may deserve a reward but he is not given it; (2) he is given a lesser reward than what was due to him; (3) he is given a punishment although he is not liable to any punishment; (4) the one who is liable to punishment is not given any punishment; (5) the one who is liable to a lesser punishment is given a greater punishment; (6) the oppressor goes Scot-free; and (7) one is seized for the sin committed by another. What Allah means to say is that none of these different kinds of injustices will be allowed to take place in His Court.
*29) It means: "It will take Allah no time to do the reckoning. Just as He is providing for every creature of the miverse simultaneously and He is not so occupied in providing for one that He may have no time to provide for others, and just as He is seeing everything in the universe simultaneously, and hearing everything simultaneously, is managing every small and big affair simultaneously, and nothing absorbs His attention so completely that He may be unable to give . attention to others, at the same time, so He will subject to reckoning every single individual simultaneously and the hearing of one case will not make Him so occupied as to render Him unable to hear other countless cases at the same time. Then in His Court no delay also will be allowed to take place due to any difficulty in the investigation of the facts of the case and the availability of the witnesses. The Judge of the Court will Himself be aware of all the facts directly. Each party in every case will stand completely exposed before Him, and clear. undeniable evidence of the events and deeds, with each minor detail, will come forward without any delay. Therefore, each case will be settled and decided instantaneously.
