The pairings yaʿṣi / yuṭīʿu (defy / obey), ḥamd / dhamm (praise / blame), yukarrim / yukarram (honor / be honored) and ziyādah / naqṣ (increase / decrease) make contrasts intellectually concise.
These are argumentative devices rather than mere ornament. Lisān al-fatā nisfun wa-niṣfun fuʾāduhu instead creates balance, while the repeated verbs of requesting and giving build an audible rhythm toward the final caution.
