الْحَقَّ أَطْلُبُ لَا الْمَدْحَ.
I seek the truth, not praise.
Fronting al-ḥaqqa brings “truth” into focus, while lā al-madḥ denies an alternative aim. The exclusive force comes from the entire contrast, not from word order in isolation.
It helps to identify predicate, subject and verbal dependents separately, but the rhetorical effect arises from their interaction.
