This research focuses on the strategy of taqiyyah in the thought and debates of Sheikh Mufid (may Allah have mercy on him), and analyzes the mechanisms and combined dimensions of tolerance, rational defense, and theological innovation in confronting intellectual and ideological opponents in the historical-social context of Baghdad during the Buyid era. Sheikh Mufid's lifetime was a period of political, social, and theological ups and downs that occupied the discursive space of Baghdad, influenced by the diversity of Islamic sects and schools, especially the confrontation between the Imamiyya, Sunnis, and Mu'tazilites. In such an environment, Sheikh Mufid used the tools of taqiyyah, especially in the forms of circularity, argumentation, and in some cases fear, to defend Shiite beliefs and respond to the doubts of opponents. This article, using a descriptive-analytical method and based on the analysis of the content of historical sources and narrative texts, has analyzed the theoretical foundations of taqiyyah, the social and intellectual contexts of the Buyid era in Baghdad, and the interactive process and effects of Sheikh Mufid's famous debates with important and influential figures, focusing on the element of taqiyyah. The main achievement of the research is the explanation of a systematic and flexible model of taqiyyah in the context of debates; a model that has played a role in the dynamics of Imami theology not only as a behavior based on caution, but also with an active, creative and strategic function. The case analysis of Sheikh Mufid's debates shows that the combination of tolerance, rational response and scientific innovation has had a significant impact on the preservation, expansion and promotion of Shiite discourse in one of the most complex periods in Islamic history.
