التبليغ — الإغراق — الغلو
Tablīgh, ighrāq and ghulūw.
Test two questions when classifying exaggeration: is the asserted event logically possible, and if so is it customarily possible? Possibility in both senses points to tablīgh; logical possibility but customary improbability points to ighrāq; logical impossibility points to ghulūw.
Impossibility does not make every exaggeration aesthetically worthless. Imaginative framing and context can support some forms of ghulūw. Degree of possibility and literary acceptability are separate judgments.
