Mentorship, as a fundamental element of the Islamic educational system, is deeply rooted in the traditions of the prophets, the Ahl al-Bayt (AS), and the righteous scholars. This pedagogical tradition is not limited to the transfer of knowledge; rather, it plays a pivotal role in shaping the religious, cultural, and civilizational identity of students. In today’s rapidly changing socio-cultural and media landscape, revisiting this tradition has become imperative. The present study aims to elucidate the significance and functions of mentorship in transmitting religious culture and in the process of Islamic civilization-building. Utilizing a descriptive-analytical method and drawing upon religious, historical, and biographical sources, this paper examines the multifaceted aspects of this tradition. Findings indicate that mentorship is a multidimensional and continuous process based on a spiritual and intellectual relationship between teacher and student, which institutionalizes values, nurtures committed elites, and contributes to the production of religious and civilizational knowledge. It concludes that reviving this tradition may address contemporary identity and epistemological crises in Muslim societies and play a strategic role in realizing the New Islamic Civilization.
