وَالِاخْتِصَاصِ فِي قَوْلِهِمْ: أَنَا أَفْعَلُ كَذَا أَيُّهَا الرَّجُلُ
An example of specification is: “I do such-and-such, O man.”
Ikhtiṣāṣ singles out the speaker’s qualification rather than attempting to call an addressee. In “anā afʿalu kadhā ayyuhā al-rajul,” the expression roughly means “I, as a man, do this.” The context can make the quality a ground for pride, modesty, or self-identification.
Anā afʿalu kadhā is a complete declarative clause. The qualifying expression identifies a dimension of the subject; its surface resemblance to a vocative should not be confused with a real request for the man’s attention.
