Background: Quality of sleep has been associated with optimum learning performance of students. Moreover, the quality of sleep was influenced by several factors, such as: physical health status, environment, diet, life style, medication, and psychological stress. While, studying in a boarding school might pose to psychological stresses, especially in the early age of adolescent, due to being separated from the parents and the requirement to be more independent. Listening to Qur’an has been implemented as a daily routine activity in Islamic boarding school. It was argued that understanding the meaning of Qur’an might influence the wellbeing of individual. The study aimed to shed some lights into how listening to surah Ar Rahman and understand the meaning might influence the quality of sleep, as one sign of psychological wellbeing. Methods: The research design was an experiment with pre-and posttest group control approach. Sampling was carried out by a random sampling technique that involved 70 respondents, divided into 35 respondents each for treatment and control group. Treatment, listening to and reading the meaning of Ar Rahman, was delivered for 14 days consecutively, whereas, the control group was only listening to Qur’an as the daily routine activity. The sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI) before and after the treatment. Data analysis was using paired sample t-test, Wilcoxon test, and Mann Whitney test. Results: There were less than 40% students with bad quality of sleep. Furthermore, there was no significant difference in the respondents’ sleep qualities before and after listening Ar Rahman along with reading the meaning between the intervention and control group (p>0,05). The limitation of the study was the lack of understanding of self-motivation among the students that might play into a role of dealing with daily difficulty in a boarding school, as well as prior individual practice of listening to Qur’an before entering the school. Conclusion: The results of this study showed that listening Al-Quran (Ar-Rahman) along with reading the meaning had no significant effect on sleep quality among grade 1 student at a junior high boarding school in Yogyakarta
