If a poet says that a flower bowed out of shyness to explain its drooping, the invented aesthetic cause may constitute ḥusn at-taʿlīl. If the poet instead intensifies the bowing to an extreme, the issue may be hyperbole (mubālaghah).
The traditional divisions of hyperbole—tablīgh, ighrāq, and ghulūw—concern rational and customary possibility. Beautiful causal explanation replaces an ordinary explanation with an imaginative one. Both may coexist in a passage, but they are analytically distinct.
