Complete jinās requires agreement in letter identity, number, vowel/form, and order, together with a difference in sense. Here the surrounding grammatical construction reveals the divergent meanings and word classes.
A change of letters or their arrangement prevents classification as complete jinās; the expression might instead fall under an incomplete subtype. Repeating the same word with the same meaning is not automatically a pun.
