Ghadīr-e Khumm as an important historical Islamic fact has been a turning point in the explanation of the Imamate and the continuation of the Islamic movement. The holy prophet Muhammad (pbuh), according to divine order, traced the inseparable correlation between Imamate and the governance and administration of worldly affairs, stating that the criterion of truth is the divine path of God in the form of infallible Imams, and this will continue until the end of Time and the appearance of Imam Mahdi (pbuh) Therefore, according to Ghadīr’s texts including Ghadir’s sermon and Ghadīriyah Ziyārat, deviant ideas such as secularism, pluralism, different interpretations from religion, tolerance in making relation to enemies and opponents, and misconceptions of Khātamiyyat (termination of Prophethood) and Mahdism will be invalidated.
