حُفِزَتْ وَزَايَلَهَا السَّرَابُ كَأَنَّهَا ۞ أَجْزَاعُ بِيشَةَ أَثْلُهَا وَرِضَامُهَا
The caravan was urged onward, while the shimmering mirage shifted away; from a distance its shapes seemed like the trees and stony heaps of the valleys of Bīshah.
Ḥafazat describes urging movement forward. Al-sarāb is the shimmering mirage visible across hot ground. Ajzāʿ Bīshah denotes valley stretches near Bīshah, while athl are trees and riḍām heaps of stones. The simile depends on shapes and colors merging in the distance.
