The elucidation of "scriptural evidence for the imaginal and noetic immateriality of the human soul" plays a fundamental role in defining human reality and charting the ascending trajectory toward the station of the "Perfect Human" (Al-Insan al-Kamil), while significantly influencing the foundations of Islamic human sciences. Utilizing a descriptive-analytical method, this research investigates the scriptural (naqli) evidence regarding imaginal and intellectual immateriality within the works of Mulla Sadra and Allamah Tabataba'i. Within the framework of Islamic philosophy and theology, reason ('aql) and revelation (naql) are mutually corroborative; hence, both Sadra and Tabataba'i emphasize the systematic presentation of rational proofs alongside Qur'anic verses and narrations. The expansion of these scriptural evidences and their integration with the philosophical principles of Transcendent Philosophy (al-Hikmah al-Muta‘aliyah) through a novel framework constitutes one of Tabataba'i's distinct scholarly innovations. The research findings indicate that regarding "imaginal immateriality" (tajarrud al-mithali), the soul’s disembodiment from matter and certain material accidents is established for all human souls—both in the temporal world and the hereafter—through evidence such as "the reality of true dreams," "the event of the Ascension" (Mi'raj), "the nature of soul-taking" (tawaffi) during sleep and death, and "the survival of imaginal forms" in the intermediate world (Barzakh). Concerning "intellectual immateriality" (tajarrud al-'aqli), the soul, through its substantial intensification (al-sayr al-ishtidadi), is recognized as being of the same nature as the "World of Command" ('Alam al-Amr) and the "Celestial Realm" (Malakut). By attaining "Pure Life" (Hayat al-Tayyiba), the soul transcends all material accidents—a station reserved exclusively for perfected souls. Ultimately, scriptural evidence transcends its role as a mere supporter; by detailing the soul's substantial motion from its material origin to the highest intellectual stations, it unveils the comprehensive map of human perfection and provides an epistemic ground for the solidification of philosophical proofs.
