كَتَكَالِيفِ قَوْمِنَا إِذْ غَزَا الْمُنْذِرُ هَلْ نَحْنُ لِابْنِ هِنْدٍ رِعَاءُ
Meaning: The poet recalls the burdens endured by his people when al-Mundhir raided, then asks scornfully whether they are merely herdsmen or servants of Ibn Hind.
Takālīf are hardships or burdens; riʿāʾ means herdsmen. The question hal naḥnu ... riʿāʾ is rhetorical: it rejects the suggestion that the tribe exists merely to serve Ibn Hind.
The names al-Mundhir and Ibn Hind belong to the historical setting. Recollection of a raid is used to assert tribal independence, not to supply a neutral chronicle of the encounter.
