In لَا يَدْخُلْنَ الْجَنَّةَ وَلَا يَجِدْنَ رِيحَهَا, two verbs are negated. The severe warning emphasizes wrongdoing, but it should not be weaponized to ridicule, harass, or pronounce personal verdicts on others.
Both groups illustrate the misuse of power or social influence. Advice should remain respectful, proportionate, and attentive to individual dignity.
For example, a discreet, informed conversation about dress or conduct is very different from public humiliation of a student.
