حُسْنُ التَّعْلِيلِ
Offering a fitting imaginative cause for an event or attribute.
In ḥusn al-taʿlīl a poet replaces an ordinary explanation with a fitting imagined cause. Substituting a scientific or historical reason might improve factual exposition while destroying the artistic device.
Criticism must first ask whether the work claims empirical explanation or cultivates poetic imagination. An unsupported causal claim may be defective in a technical report but can function differently in a literary passage.
