Psychological tranquility is one of the most essential human needs in facing the challenges of modern life. This study aims to analyze the stylistic features of the comforting verses of the Holy Quran and their impact on reducing anxiety and psychological stress. The main research question is: How do the linguistic and rhetorical characteristics of the Quranic verses, particularly those related to tranquility and serenity (Sakinah), contribute to reducing anxiety and psychological stress? The research adopts a descriptive-analytical approach and relies on library studies. By utilizing Quranic verses and psychological concepts, the study explores the relationship between divine language and its effects on the human psyche. The findings indicate that the rhetorical structures and spiritual concepts of the Quranic verses, through fostering a sense of security, hope, and connection with a higher source, lead to a significant reduction in anxiety and psychological stress. These results highlight the importance of the Holy Quran as an inspirational source for enhancing mental well-being and suggest its potential as a complementary approach in psychological therapies.
