The formation of a cult occurs not only through direct teachings but also through the active involvement of her followers on Instagram, which strengthens the bonds within the digital community. Moreover, Ustadzah Halimah's charisma is recognized and reinforced by her followers, aligning with Weber's definition, where charisma stems not only from her personal qualities but also from the acceptance of her followers. Ustadzah Halimah's charisma was not solely derived from herself, but was co-constructed by the community that formed a cult around her. Ismail Fajrie Alatas emphasizes that authority is not merely position or power, but the ability to build temporal relationships, connecting past values with the current context, and creating a community that can internalize these values (Cultivating Community). Da'wah through the Instagram account @halimahalaydrus illustrates how identity, cult, and charisma evolve in the digital age, highlighting significant changes in the construction and maintenance of religious authority.
