التبليغ — الإغراق — الغلو
Possible intensification, improbable exaggeration, and impossibility.
Tablīgh reaches an extreme still rationally and ordinarily possible; ighrāq is rationally possible but ordinarily improbable; ghulūw involves a rationally impossible assertion. Imaginative framing can make a form of ghulūw rhetorically effective under suitable conditions.
The logical category of the claim and its artistic success are separate judgments.
