وَقَالَ أَلَا مَاذَا تَرَوْنَ بِشَارِبٍ
شَدِيدٍ عَلَيْنَا بَغْيُهُ مُتَعَمِّدِ
Meaning: The complainant asks those present what they think of a drinker who has acted aggressively toward them and deliberately committed an offense.
Shārib is a drinker (here of wine), baghyuhū his aggression or wrongful conduct, and mutaʿammid someone acting intentionally. These descriptions occur in the complainant's accusation: identifying the speaker prevents us from treating every characterization as the poet's own narration.
