The science of rhetoric has a special function in proving the miracle of the Qur'an's expression, and one of its obvious manifestations is the eloquent simile, which by removing similes and similes, causes more exaggeration and plays a great role in the beauty of words. The present research, with descriptive-analytical method, analyzed the approach of literary interpretations of "Al-Kashf", "Majmam Al-Bayan" and the effect of rhetorical arts and specifically, eloquent simile in expressing the concepts of the Holy Quran and how two commentators approach this art of expression. has been investigated. Based on the obtained results, in terms of form, Tabarsi, unlike Zamakhshari, explicitly mentions similes in a small number of verses, especially Baligh similes.To explain the analogy of the verses, Tabarsi goes more to the narrations and generally does not try to prove a particular opinion, but Zamakhshari pays more attention to the rhetorical arts and concepts derived from the Quranic vocabulary. He mostly explains the similes used in the Qur'an by using other verses and Arab poems, and sometimes he uses the available space to prove the Mu'tazila and reject the opinions of his opponents. Based on the content classification of eloquent similes, which is more than 35 verses in the Qur'an, Tabarsi has the upper hand in presenting "religious and scientific" concepts, and the explanation of the contents has been well done by him, while Zamakhshari in the topics of "social and Hakam" which is based on the eloquent simile, has had a more visible function.
