وُجُوهٌ يَوْمَئِذٍ خَاشِعَةٌ ۞ عَامِلَةٌ نَاصِبَةٌ ۞ تَصْلَىٰ نَارًا حَامِيَةً ۞ تُسْقَىٰ مِنْ عَيْنٍ آنِيَةٍ
Some faces that Day will be humbled, toiling and exhausted; they enter a blazing fire and are given drink from a boiling spring. (88:2–5)
Wujūhun is an indefinite subject, with “downcast” as its predicate; “toiling, exhausted” adds further predications or descriptive information. The subsequent contrasting class of faces also clarifies why the indefinite subject is meaningful here.
Tusqā is passive: attention falls on the dreadful experience of being made to drink, not on the identity of the giver. The compact succession of clauses builds one continuous depiction of distress.
