To answer this question...

To answer this question, we say that: the denial of the Resurrection, in an absolute form, does not decisively exist even among the unbelievers, because many of them assume that there is the existence of the spirit after death, or in other words, ‘the spiritual Resurrection’. Some of them were doubtful about the bodily Resurrection as in Surah Naml No.

27, verse 66: “Still less can their knowledge comprehend the Hereafter: nay, they are in doubt and uncertainty regarding it, nay, they are blind thereunto!”. And some of them completely denied the Resurrection and even said that the Prophet (S) was mad, because of his claim about Resurrection; as in Surah Saba, No.

34, verse 7‑8: “The Unbelievers say (in ridicule): Shall we point out to you a man that will tell you, when you are all scattered to pieces in disintegration, that you shall (then be raised) in a New Creation?”. “Has he invented a falsehood against Allah, or has a spirit (seized) him? Nay, it is those who believe not in the Hereafter, that are in (real) Penalty, and in farthest Error”. Thus, their rejection of the Resurrection is certain. It further states: “Nay! they shall soon (come to) know”.

“Nay indeed! they shall soon (come to) know”. When they will be informed, they will cry and will be sorry for themselves; each of them saying: “Lest the soul should (then) say: Ah! Woe is me! in that I neglected (my Duty) towards Allah...” [^3] On the Day that they are surrounded by massive punishment, and they wish to return to their former life, they ask: “Is there any way (to effect) a return?” [^4] .

Even when they, being at the point of death, are sure about the partition and Resurrection; because all the curtains will be removed, then, and the facts of the next world will became obvious, they cry saying: “...O my Lord! send me back (to life)”, “In order that I may work righteousness in the things I neglected...” [^5] .

The Arabic term /saya’ lamun/ ‘they shall soon come to know’ begins with ‘ ** ** س ’ (s) which is usually used as a sign for near future, and denotes that the Hereafter is near; that this whole life is just a fleeting moment in comparison to it.
