Translation of the verse 52 from Surah Ya-Sin : Number of verses 83 - - page 443 - Part 23.
They will say: "Woe to us! Who has raised us up from our place of sleep." (It will be said to them): "This is what the Most Beneficent (Allah) had promised, and the Messengers spoke truth!"
They will say, "O woe to us! Who has raised us up from our sleeping place?" [The reply will be], "This is what the Most Merciful had promised, and the messengers told the truth."
(36:52) (nervously) exclaiming. 'Alas for us! Who roused us out of our sleeping-place?' *48 'This is what the Merciful One had promised, and what (His) Messengers had said was true.' *49
*48) That is, "At that time they will not realize that they had been dead and had been raised back to life after a long period, but they will be thinking that they had fallen asleep, and had been woken up suddenly by some terrible catastrophe, and were running away from it." (For further explanation, sec Ta Ha: 103, AI-Hajj: 1-2).
*49) Here, it is not clear as to who will give this answer. It may be that they themselves would realize after some time to their horror that it was the same thing of which the Messengers of God used to inform them and they used to belie them. It may also be that the believers will remove their misunderstanding and tell them that it was not waking up from sleep but the second life after death. And it may also be that they will understand this from the general conditions prevailing on the Day of Resurrection ar the angels might tell them this.
