Imam Husain ibn Ali's legacy stands as a pivotal moment in Islamic history, with his sacrifice at Karbala viewed as a vital act that protected the core values and principles of Islam during a time of serious threat. This sacrifice was not just a personal or familial tragedy, but a courageous act to preserve the teachings of his grandfather, Prophet Muhammad. Following the Prophet's death, the Muslim Ummah's leadership changed hands, leading to a significant shift in the Islamic world's political and spiritual landscape. This shift was evident when Muawiya ibn Abi Sufyan established the Umayyad dynasty, turning Islamic governance into a monarchy instead of the just and spiritual leadership as established by the Prophet.
