الْعَدْلَ نُرِيدُ، لَا الْمُحَابَاةَ.
What we seek is fairness, not favoritism.
The object “al-ʿadla” precedes its verb; the following negation makes the preferred and rejected alternatives conspicuous. Because the contrast is stated, an interpretation of focus or exclusivity is stronger than in a context-free preposed object.
“We want fairness” is also a valid assertion. The change lies primarily in focus: the fronted object leads the utterance, and the rejection of favoritism sharpens the rhetorical contrast.
