أَمْ عَلَيْنَا جَرَى قُضَاعَةَ أَمْ لَيْسَ عَلَيْنَا فِيمَا جَنَوْا أَنْدَاءُ
Translation: Or are Quḍāʿah’s offences laid on us? Are we not free of obligation for what they committed?
Quḍāʿah names a tribe. Fīmā janaw contains the masculine plural past verb janaw, from j-n-y, “what they did wrong.” The commentary interprets the ending as denying that their offence binds the poet’s people.
This is a continuation of the same argumentative chain, not a new unrelated battle story. The recurring question rejects being held answerable for other parties’ actions.
