Commentary on Tafsir al-Jalalayn: ((And they said)) meaning the disbelievers ((O)) is for emphasis ((Woe to us)) our destruction, and it is a verbal noun with no verb derived from its form

Then they look in astonishment. And they said, meaning the disbelievers, O is for emphasis, woe to us, our destruction, and it is a verbal noun with no verb derived from its form. And the angels say to them, this is the Day of Judgment. Now, they said using the past tense verb, even though the speech is future, to confirm its occurrence. This is common in the Arabic language and the Noble Qur'an, to express the future with the past... to confirm its occurrence. An example of this is His saying, the Exalted: So the command of Allah did not come with evidence of His saying: But here it came in the meaning of "will come," and the future was expressed with the past to confirm its occurrence. So His saying, the Mighty and Majestic, here, "and they said" means "and they are saying," but He expressed it with the past to confirm its occurrence. And his saying "meaning the disbelievers" is correct in that, and if he had said "and they said, meaning the deniers of the Resurrection who said: " it would have been more precise in the exegesis, because the disbeliever is broader than the denier of the Resurrection, is that not so? One may disbelieve without denying the Resurrection, but the matter has some leniency in expression.
And his saying: The author said that O is for emphasis, and that wail is a verbal noun for a deleted, implied verb from its meaning, not from its form. But it is possible that O is a particle of calling, and that they called out to the wail, as if they said, O our wail, come, for this is your time. And the meaning of wail here is severe regret and punishment as well. Allah, the Exalted, said: meaning regret and punishment. So here, O our wail means O our regret and our punishment, come, for this is your time. And it is possible, as the author said, that the ya is for emphasis. But if someone asks, does the ya come for emphasis? The answer is yes. If we are asked for an example that cannot be anything but emphasis, we say, like His saying, the Exalted: So the ya here is for emphasis, because the ya does not enter upon particles, but only upon nouns, yet it was brought for emphasis.
And his saying: our destruction. But the wail, as I said, is more specific than mere destruction; rather, it is regret and punishment. It is a verbal noun with no verb derived from its form, but from its meaning. If it is from its meaning, and we interpreted the wail as destruction, how do we estimate the verb? We perished, our destruction. So, this is the Day of Judgment. The author said, and the angels say to them, this is the Day of Judgment. So the exegete, may Allah have mercy on him, attributed this is the Day of Judgment to the speech of the angels.
