قَدْ أَفْلَحَ مَنْ زَكَّاهَا وَقَدْ خَابَ مَنْ دَسَّاهَا
Flourishing belongs to whoever purifies the soul; loss to whoever buries or corrupts it. (91:9–10)
The two clauses are nearly balanced in the pattern “qad + past verb + man + verb + pronoun.” Alongside the structural balance, aflaha/khāba and zakkāhā/dassāhā are semantic opposites.
Whatever detailed analysis one adopts for man and for how purification occurs through human action and divine enabling, the rhetorical judgment links the two contrasting outcomes to the two contrasting orientations.
