وَرُحْنَا يَكَادُ الطَّرْفُ يَقْصُرُ دُونَهُ مَتَى مَا تَرَقَّ الْعَيْنُ فِيهِ تَسَفَّلِ
Then we returned, and the gaze almost failed to take in the horse’s full figure; whenever the eye rose to view his upper form, it fell back down.
Wa-ruḥnā introduces the return. Yakādu l-ṭarfu yaqṣuru dūnahu depicts the eye as unequal to fully taking in the horse’s imposing beauty and proportions.
The eye rises toward his higher features but comes back down. Motion has changed form: the horse is no longer the focus of a chase; the gaze itself moves.
