The art of dividing the metaphor and the characteristics of the text, counted Fakhr al-Din al-Razi in his book The End of Briefness in Derayat al-Ijaz

In this study, I tried to show the features of what Fakhr al-Din al-Razi stated in his explanation of metaphor by carefully reading the texts and extracting his responses to the rhetoricians and his rhetorical opinions: starting with his response to the definition of metaphor, the reasons for his response, and his appropriate and comprehensive definitions of its places, as he sees it, all the way to the metaphors mentioned in The Quranic verses are in the form of points that make it easier for the reader to understand the meaning of metaphor, what he invalidates and removes from metaphors, and the grammatical and morphological positions of metaphor and its figurative connotations. Therefore, Al-Razi was distinguished from other rhetoricians in:
1_ The accuracy and quality of his division of the topics of his book, especially (metaphor). I looked at most of the rhetorical books from the sixth century to the end of the ninth century AH, in addition to the most famous books in the period that preceded them, and I did not find a better division and arrangement than him.
2_ Most of his divisions began by invalidating some of the rules of rhetoricians that had been used, and presenting his applied inferences.
3_He has his own style of presenting and analyzing rhetorical material. He did not take it from anyone for the purpose of transmission or analysis. Therefore, he differed from all the rhetoricians of his time in his conviction about something, his violation of rhetorical rules, and his adoption of what he found desirable.
And it turns out
1_There is no comprehensive definition for the concept of metaphor with all its details and names, either for fear related to its grammatical position in the sentence, or for its confusion with simile, so two definitions were given to it as we mentioned previously.
2_With this research, we were able to reach the conditions for the occurrence of metaphor through meaning - language, determine its grammatical position, and extract metaphors from being metaphors through their grammatical position.
