As for the plural in one book, that is when two nouns call it and more, or a name that includes two names and more, as we have mentioned, then in that one book it responds to them according to what they were called to, like the singer, if he calls him to it, then he includes in what is called the rule of the noun al-mu’izz, for if he is self-sufficient, he is proud, and glory is not there. Except from the name al-Mu'izz, and what is cherished here is only the name al-Mughni because it enriched it, so I inherited from it the characteristic of the rich, glory. If al-Mughni had not included the name al-Mu'izz, pride would not have appeared in this rich person because he was rich with it .
