A short Qur’anic phrase may sometimes show an approximate resemblance to a poetic pattern. Such resemblance does not establish that Qur’anic discourse continuously obeys that metre. Exact metrical agreement requires the relevant line as a whole to meet the formal conventions of its poetic system.
This distinction is especially useful when a few words are scanned metrically and then treated as proof that the Qur’an is poetry. Resemblance in an isolated fragment does not determine the genre or structure of the complete verse and its context.
The governing rule: partial coincidence does not amount to identity of form. The discourse must be evaluated as a coherent whole.
