من راقب الناس مات غمًّا
Whoever keeps watching people dies of grief.
Sallām replaces Bashshār's lam yaẓfar bi-ḥājatihi (does not gain his aim) with māta ghamman (dies of grief). The new expression portrays an extreme emotional consequence rather than simply the failure to achieve a goal.
The language is hyperbolic and does not require a literal death. The recasting intensifies the psychological effect of excessive attention to others.
