Generality is not confined to ordinary nouns carrying al-. Relative expressions can also encompass every member satisfying the relative clause. The text considers relative forms such as «الَّذِينَ» in the discussion of exhaustive meaning, while keeping their linguistic structure distinct.
أَكْرِمِ الَّذِينَ يَأْتُونَكَ
Honour those who come to you.
This teaching example shows that everyone within the relative-clause description can fall under the command. However, «الذين» is a relative form, not simply a common noun preceded by an independent article. Similar inclusive force does not make their syntax identical.
