<![CDATA[Electroencephalography (EEG) provides a non-invasive means of monitoring brain activity and is widely used to investigate neural responses to cognitive, emotional, and sensory stimuli. Among EEG frequency bands, alpha (8–12 Hz) activity is commonly associated with relaxation and internal attention, whereas beta (12–35 Hz) activity reflects active cognitive processing, alertness, and sensorimotor functions. Although several studies have examined the effects of Qur'anic recitation on brain activity, changes in alpha and beta oscillations during listening to the Holy Qur'an remain insufficiently characterized. Therefore, this preliminary study aimed to investigate the effects of listening to the recitation of the Holy Qur'an (Surah Ar-Rahman) on EEG signals in both the time and frequency domains. EEG recordings were obtained from three healthy participants using 22 electrodes positioned according to the international 10–20 system. Brain activity was recorded for approximately 30 minutes, and Fourier transform analysis was performed to extract alpha and beta frequency components. Compared with the baseline condition, Participant 2 showed increased alpha-band amplitude in approximately 86% of the recorded EEG channels during Qur'an recitation compared with beta band. These findings suggest that listening to the recitation of the Holy Qur'an may enhance alpha oscillatory activity, reflecting a more relaxed and internally focused brain state. However, individual responses vary depending on the subject’s condition, even when exposed to the same stimulus. Further studies involving larger sample sizes are required to validate these preliminary observations.]]>
