The poetic example uses an oath, an apparent objection, and a counterfactual formulation to turn praise into something resembling a proof. A phrase such as حلفت فلم أترك لنفسك ريبة introduces an emphatic claim and then responds to the likely doubt.
The poet’s evaluative goal must be distinguished from the inferential structure. The language of premises and *law* gives praise an argumentative form; it does not make every idealized claim an empirically verified fact.
