Mahdism is one of the fundamental doctrines of Islam, holding a special status in the Quran and the sayings of the Ahl al-Bayt (A.S.). As a distinguished contemporary mystic and jurist, Ayat-Allah Muhammad Taqi Bahjat offered a spiritual and esoteric perspective on Mahdism in the light of Quranic verses. Employing a descriptive-analytical approach, this research aims to analyze the characteristics of his Quranic-spiritual view on Mahdism and examines how he utilized Quranic verses to elucidate topics such as Occultation, the duties of those awaiting, and the levels of meeting the Imam (Tasharruf). Findings indicate that Ayat-Allah Bahjat, with an approach distinct from text-oriented (literal) exegesis, focuses on linking verses with individual spiritual conduct and the spiritual upbringing of the Muntazirin. Emphasizing the Quran and the Imam as counterparts, focusing on verses regarding patience, piety, supplication, and servitude as essential elements of Waiting, and viewing the Reappearance as an inner process are characteristics of this perspective. His Quranic allusions offer a practical and ethical model for a "waiting lifestyle" that can guide believers during the era of Occultation.
