كَأَنَّ جَنَاحَيْ مَضْرَحِيٍّ تَكَنَّفَا
حِفَافَيْهِ شَكًّا فِي الْعَسِيبِ بِمِسْرَدِ
It is as though the two wings of a pale vulture flank her tail, fastened along its core as if stitched with a needle.
Maḍraḥī denotes a pale kind of vulture. The focus is the hair-bearing extent on both sides of the tail. Al-ʿasīb is the tail’s central bone, while al-misrad is a stout needle or stitching implement.
The image does not claim that the she-camel possesses wings; it visualizes the way the tail’s two sides spread and appear securely attached.
