وَقَدْ خَابَ مَن دَسَّىٰهَا
and doomed is the one who corrupts it!
Compare 91:10 and 91:9
highlighted words differ between verses
قَدْ أَفْلَحَ مَن زَكَّىٰهَا
Successful indeed is the one who purifies their soul,
Consecutive antithetical verses — 91:9 'qad aflaha man zakkaha' (successful is he who purifies it) and 91:10 'qad khaba man dassaha' (failed is he who buries it) — swapping them is a common error.
