Surah 69. Al-Haqqah, Ayah 1

I.e., the Day of Resurrection and Judgment, on which man will become fully aware of the quality of his past life and, freed from all self-deception, will see himself as he really was, with the innermost meaning of all his past doings - and thus of his destiny in the hereafter - blindingly revealed. (Cf. 37:19 , the last sentence of 39:68 , and {50:21-22}.)

Al-haqqa: the sure Truth: the Event that must inevitably come to pass; the state in which all falsehood and pretence will vanish, and the absolute Truth will be laid bare. The questions in the three verses raise an air of wonder. The solution is suggested in what happened to the Thamud and the 'Ad, and other people of antiquity, who disregarded the Truth of Allah and came to violent end, even in this life,-Symbolically suggesting the great Cataclysm of the Hereafter, the Day of Doom.
