A report concerning ʿAbd Allāh ibn al-Zubayr and the poet Maʿn ibn Aws illustrates a dispute over verses and their attribution.
إذا أنت لم تنصف أخاك
If you do not deal justly with your brother.
The line begins a cited poetic example of taking earlier verse together with its verbal composition. The report functions here as a transmitted literary illustration, not as independent adjudication of an historical legal case.
