Ghulūw goes further: the attributed degree exceeds logical possibility.
An extraordinary human quality might be described at a level whose literal occurrence is logically impossible. In poetic ghulūw, the poet deliberately creates this picture to convey extreme intensity.
An actual religious statement of fact should not be confused with literary hyperbole. The analysis concerns what the poet alleges for effect, not the truth conditions of revelation.
Ghulūw in poetry therefore functions as a rhetorical image and its acceptability depends on its form and context.
