إِرَمِيٌّ بِمِثْلِهِ جَالَتِ الْخَيْلُ وَتَأْبَى لِخَصْمِهَا الْإِجْلَاءُ
Meaning: He is of the line of Iram; cavalry move around a man of such standing, and the cavalry refuse to be driven from their homeland by their opponent.
Iramī is a lineage adjective: Iram is named as an ancestor in the line of ʿĀd. Jālat al-khayl evokes cavalry circling or moving in battle; al-ijlāʾ means expulsion or forcing an opponent to retreat.
The genealogical claim and the cavalry image enhance the ruler’s stature. The scene is a literary expression of power, not a literal description of a stable or a troop count.
