The psychological miracle of the Quran, as a less explored dimension of the miracle of this divine book, with a profound impact on the psyche of the individual and society, provides a novel field for research. The view of Karen Armstrong, a prominent Western religious scholar, who considers the Quran to be a living and reactive text, along with modern Islamic theories, creates a necessity for a comparative analysis of this phenomenon. The aim of this research is to interpret the psychological miracle of the Quran in the light of Karen Armstrong's hermeneutics and Islamic theology, with an emphasis on the emotional, cognitive, and existential aspects of the verses. The research, with a qualitative and analytical approach, uses the method of content analysis of Armstrong's works ("History of God", "Muhammad: A Prophet for Our Time") and Islamic sources ("Al-Mizan", "Tafsir Al-Namneh" and other authentic and authentic exegetical and Islamic sources) and provides an interdisciplinary framework by analyzing various verses. The findings show that Armstrong, citing verses such as “O mankind, there has come to you a sermon from your Lord” (Yunus/57), considers the Quran as a factor for healing the soul and creating a mystical experience, and emphasizes verses of fear, glad tidings, and stories, but pays less attention to the nature of revelation. In contrast, Islamic theories, with verses such as “And seek help through patience and prayer” (Baqarah/45), attribute psychological effects to divine guidance and emphasize resilience and social reform.
