تُبَارِي عِتَاقًا نَاجِيَاتٍ وَأَتْبَعَتْ
وَظِيفًا وَظِيفًا فَوْقَ مَوْرٍ مُعَبَّدِ
Meaning: She keeps pace with fine, fleet camels, placing one lower leg after another upon a well-trodden track.
Tubārī is to match or compete with others. ʿItāqan nājiyāt refers to well-bred, swift she-camels. Repeating waẓīfan waẓīfan reproduces a cadence of successive strides, one after the other.
Mawr muʿabbad indicates a beaten track or passable surface. Speed is shown through competition, rhythm of limbs, and contact with the road, not merely asserted.
