Translation of the verse 55 from Surah Ar-Rum : Number of verses 60 - - page 410 - Part 21.
And on the Day that the Hour will be established, the Mujrimun (criminals, disbelievers, polytheists, sinners, etc.) will swear that they stayed not but an hour, thus were they ever deluded [away from the truth (i.e. they used to tell lies and take false oaths, and turn away from the truth) in this life of the world)].
And the Day the Hour appears the criminals will swear they had remained but an hour. Thus they were deluded.
(30:55) On that Day when the Hour will come to pass *80 the wicked shall swear that they had stayed (in the world) no more than an hour. *81 Thus they used to be deceived in the life of the world. *82
*80) That is, Resurrection, which is being foretold here.
*81) That is, from the time of death till Resurrection. Even if thousands of years might have elapsed since their death they will feel that they had gone to sleep a few hours earlier and then a sudden calamity had roused them froth sleep.
*82) That is, "They used to make similar wrong estimates in the world, There also they lacked the realization of Reality, and therefore, used to assert there was going to be no Resurrection, no life-after-death, and no too. that accountability before God."
