وَمَا أَدْرَاكَ مَا يَوْمُ الدِّينِ ۞ ثُمَّ مَا أَدْرَاكَ مَا يَوْمُ الدِّينِ
And what will make you know what the Day of Recompense is? Then again, what will make you know what that Day is? (82:17–18)
These are not straightforward requests for information; they serve magnification and awe. The repeated question, now introduced by “thumma,” signals an importance beyond ordinary expectation. Thumma may indicate escalation in rank rather than simply a chronological interval.
The clarification comes in the following verse, not immediately after the first question. This is an effective form of clarification after arousing uncertainty: the question produces suspense and the subsequent statement supplies the decisive characteristic of the Day.
