During the reign of Muʿāwiyah ibn Abī Sufyān, the public cursing of Amīr al-Muʾminīn ʿAlī (a.s.) became officially prevalent under the Umayyad caliphate. This innovation laid the groundwork for the emergence of the Nāṣibī movement, the effects of which persist to this day. The central question of this research is: what were the positions and reactions of the Prophet's companions (ṣaḥābah) in the face of this innovation of publicly insulting Amīr al-Muʾminīn ʿAlī (a.s.)? In what ways can these reactions be categorized and compared? And what impact did their stances have? This article, employing a descriptive-analytical method based on the content analysis of historical documents, concludes that the companions' reactions to the innovation of publicly insulting Amīr al-Muʾminīn ʿAlī (a.s.) fall into three categories: "supportive," "silent," and "confrontational." Specifically, a number of companions aided the Umayyad rulers in promoting this innovation or adopted a neutral stance by remaining silent. However, another group actively confronted this innovation. The confrontational movement was active in three main areas: "stating virtues," "protest migration," and "verbal struggle to the point of martyrdom." They countered this innovation by propagating and disseminating the virtues of Amīr al-Muʾminīn (a.s.), migrating from Umayyad-controlled territories in protest, and ultimately engaging in verbal struggle with steadfastness, even to the point of martyrdom. Although these confrontations did not develop into a widespread movement and could not prevent the officialization of the policy of public cursing, they did contribute to the expansion and preservation of prophetic traditions (ḥadīth) regarding the virtues of Amīr al-Muʾminīn ʿAlī (a.s.) and ultimately helped to gradually end this innovation during the era of ʿUmar ibn ʿAbd al-ʿAzīz, while also strengthening the arguments for the legitimacy of the Ahl al-Bayt (a.s.) school of thought.
