Discourse Analysis of Imam Riḍā's (as) Monotheistic Sermon

This research aims to examine and analyze the monotheistic sermon of Imam Riḍā (as) with an analytical-descriptive form approach, based on the operational method of discourse analysis (Pedam) in five discourse spaces: "theoretical-structural space", "semantic-value space", " communication-identity", "discourse space", and "meta-discourse space"; and then extract and draw the basic signs and finally the semantic map of the said sermon using this method. In order to achieve this goal, the research has tried to decipher Imam Riḍā's (as) expression style in the monotheism sermon, and explain the array of deep philosophical concepts of monotheism, and the discovery of the underlying semantic layers of the sermon and its unspoken explanations, and then extract the discourse that governs it and the processes affecting its. The most important results obtained from the analysis of the monotheistic sermon show the continuity, coherence and harmony of the phrases, the selection and use of familiar and common words that are understandable for the society, the accuracy in the order and arrangement of the words and concepts mentioned, and the musical rhythm arising from the melodious words and phrases and their rhyme, so that all these have caused the style of delivering the sermon to be one of the most eloquent and expressive styles for expressing deep philosophical meanings, and created a text that all its phrases form a coherent map of meaning that is inseparable. In the analysis of this sermon, we also see examples of intertextuality; Imam Riḍā (as) makes the verses of the Qur'an the main focus of his discussion; some parts of the sermon evoke Quranic concepts, and some of them evoke the sayings of Imam Ali (as), which are influential in discovering the discourse space of the sermon. The basic signifiers, meta-discourse and semantic map obtained from the analysis of this sermon indicate its semantic depth about knowing Almighty Allah, which briefly includes the following: 1. complete faith in Allah; 2. the lack of difference between essence and Allah's attributes; 3-Allah is not impressionable.
