Comparison of the Persuasion Techniques of Imam Ali in the Poetry of Seyyed Hemyari and Naser Khosrow based on Grammatical and Non-Grammatical Coherence

A Significant part of Literary texts in both Arabic and Persian Languages is included in Committed Literature. Instilling the Authenticity of Imam Ali to the Audience is the Objective Manifestation of this type of Literature in the Past era. Seyyed Hemyari and Naser Khosrow are among the Poets who Praised the Qualities of Imam Ali with Heartfelt knowledge, Sincerity, and thought. They Wrote good Poems with themes from the Verses of the Holy Quran, Hadiths and Historical events. Based on the Descriptive-analytical Method, this Research Compares some Persuasion Techniques in the Poems of both Poets in Depicting the Righteousness of Imam Ali. On the other hand, Persuasive tactics have been Measured with the Criterion of Coherence, which is Proposed in Halliday's Role-Oriented theory. The Lexical, Grammatical and Linking Coherence of the text has helped both poets to Convince the Audience by Creating an Atmosphere of Confirmation and Explanation and Sometimes Expansion and Renewal in order to reach the Authenticity of Imam Ali. Lexical Cohesion, Especially Repetition, which is Considered one of the Main Techniques of Persuasion, has a high Frequency in the Poetry of both Poets. Also, causal Relationship has a more Significant role in Shaping Persuasion Techniques than other Components of Cohesiveness. Grammatical Coherence is less used in Persuasion Techniques by the Two Poets. The Reason for the Authors' interest in these two Poets is the Almost Similar life and age Conditions of the two Poets and of Course their way of thinking, which is to inform the people of their time about the Virtues of Imam Ali.
