أنا ابن جلا وطلاع الثنايا متى أضع العمامة تعرفوني
I am Ibn Jalā, one who scales difficult passes; when I remove my turban you will recognize me.
The original boast speaks in the first person: anā, aḍaʿ, taʿrifūnī. In the textbook's example the same famous wording is adapted to describe someone else: huwa ibn Jalā and matā yaḍaʿ al-ʿimāmah taʿrifūh.
Pronouns and verbs change, yet the recognizable literary allusion survives. It demonstrates a permissible small adjustment of the incorporated verse.
