في تخصيص الفرد: زيد
“Zayd” illustrates specifying an individual.
When the name refers to a known person, it denotes that particular individual, not all people. Many persons may share the name, but context determines the intended bearer.
For instance, “Zayd is present” predicates presence of a particular individual. It does not mean that everyone is present. Individual determination is central to this use of khāṣṣ.
