Critical discourse analysis with a and interdisciplinary area, in addition to the structure of the text, examines the social functions of the text and with a critical view, it examines the hidden relations of power and political, cultural, and ideological processes in the text through rhetoric, syntax, and situational and intertextual contexts and depicts discourse contrasts. Shaqshaqiya Sermon is an interesting critical discourse. The present research, with a descriptive-analytical approach based on Norman Fairclough's critical discourse model, examines the discourse of Shaqshaqiya Sermon in three levels of description, interpretation, and explanation in order to discover how to criticize the performance of the caliphs by Imam Ali (AS) and his method of criticizing the deviations and sufferings of the Islamic society after the demise of the Messenger of God and also how to depict the public allegiance of the people to the Imam and to reveal the relationship between power and ideology in the mentioned discourse. The results show that in the level of description, the Imam tries to show the contrast between Alavi justice-seeking discourse and the rival's discourse. so that in the level of interpretation, by using the verses of the Qur'an, he tries to explain his knowledge, and his disinterest in the unjust caliphate and to express the vile traits of Nakesin, Qasetin, and Mareqin. In the level of explanation, Ali (AS), in addition to preventing the deviant ideology from rising to power again, tries to provide the basis for the reproduction of the original Islamic discourse.
