Discursive Stylistics of the 28th Sermon of Nahjulbalagheh from the Perspective of Ideational and Interpersonal Metafunction: A Study in Halliday Systemic Functional

This research aims at studying  the discursive stylistics of the 28th sermon of Nahjulbalaghah from the perspective of two ideational and interpersonal  metafunctions of Halliday's Functional Theory alongside the  frequency of processes in the dissertation of thinkers and the way of formation and formulation of meaning in the layer of communication with the audience for expressing the discourse at the level of intertextuality. By adopting an analytical and descriptive  research methodology, the current research seeks to apply the Halliday's theory in two levels of ideational and interpersonal metafunction, which is a descriptive discourse of the world and attempts to explain the discursive stylistics of the 28th Sermon of Nahjulbalaghah.
The innovation of the research is that no research has been done on the analysis of Nahjulbalagha Sermons especially sermon 28 as a discoursive study.   The results showed that the analysis of sermon's chapters at the ideational metafunction level indicates the highest frequencies of ideational processes belonging to material processes. By employing the frequency of material processes, the Prophet seems to try to tangibly express his attitude to the ephemeral features of the world and act for the hereafter.
