Allahs decisive declaration —Unquestionably, it is they who are the corrupters— removes all ambiguity. The hypocrites do not merely cause harm incidentally; they are constitutively corrupters. The phrasebut they do not perceiveis, for , the most chilling element: the deepest corruption is invisible to the one committing it. When a person's spiritual perception is clouded, they cannot see the truth about their own condition. This is why self-knowledge, cultivated through sincere worship and honest reflection, is so central to the Quranic path — it is the only antidote to the blindness the hypocrites exemplify.
