It is obvious that having chastisement in such times is more dangerous for people than in some other times. "So their cry, when Our punishment came unto them, was not save that they said: 'Verily we were unjust '." When Allah’s chastisement was sent down, the only matter they stated was that they said that they were unjust.
Thus, when they saw the punishment of Allah with their own eyes, or when they were involved in the Divine chastisement and were still rather alive, they began to confess their faults. This indicates that admission, confession of one's sins, and repentance at the time of befalling calamities and wretchedness are not beneficial for the one.
Here, in this verse, the existence of punishment and reckoning in the Hereafter is stated with several emphases. In these two verses, the certainty of the existence of question on the Day of Judgment and that it is not specialized to the sinners alone, is mentioned, too. Explanations On the Day of Judgment, surely all people will be questioned, including: both the leaders, the nations and followers, both the good doers and the evildoers, and both the scholars and the imitators of them.
"Then certainly we will question those to whom (Our messengers) were sent, and certainly we will also question the messengers." In the next verse, in order that no one considers that questioning from communities and their concerning prophets can be an evidence that there is some thing concealed from Allah’s knowledge, clearly and with an emphasis strengthened with an oath, it implies that Allah will explain all their deeds to them with His Knowledge, because He has never been absent from them.
He (S.w.T.) has been with them everywhere and in all circumstances. The verse says: "Then certainly We will relate to them with knowledge for We were not absent." On that Day, questioning is a kind of calling to witness, making confession and reprimand. But the fact is that there is nothing concealed to Allah to be discovered by question.
