The psychological miracle of the Quran—an under-explored dimension of this divine book’s miraculous nature—offers a novel field of study due to its profound impact on the psyche of both the individual and society. The perspective of Karen Armstrong, a prominent Western scholar of religion who views the Quran as a living and interactive text, creates—alongside modern Islamic theories—a need for a comparative analysis of this phenomenon. This research aims to examine the Quran's psychological miracle by comparing Armstrong’s views with Islamic theories, focusing on the emotional, cognitive, and existential aspects of the verses. Employing a qualitative and analytical approach, the study utilizes content analysis of Armstrong’s works (such as *A History of God* and *Muhammad: A Prophet for Our Time*) and Islamic sources (including *Al-Mizan*, *Tafsir-e Nemuneh*, and other authoritative exegetical and Islamic texts); by analyzing a variety of verses, presents an interdisciplinary framework. The findings indicate that Armstrong—citing verses such as "O mankind, there has come to you an instruction from your Lord" (Yunus: 57)—views the Quran as an agent for psychological healing and the generation of mystical experiences, emphasizing verses related to fear, glad tidings, and narratives, yet paying less attention to the revelatory nature of the text. In contrast, Islamic theories—referencing verses like "And seek help through patience and prayer" (Baqarah: 45)—attribute these psychological effects to divine guidance and emphasize resilience and social reform. The convergence of these two perspectives regarding the enhancement of meaning-making, alongside their divergence regarding metaphysical foundations, demonstrates their complementary nature. The innovation of this article lies in integrating Western hermeneutic analyses with Islamic theology to present a comprehensive understanding of the psychological miracle of the Quran.
