The Concept of Sleep in the Qur’an: An Analysis of I‘jāz Ṭibbī and Its Relevance to Modern Medical Science

Abstract

Sleep is an essential biological necessity for human beings. The Qur’an has described the function of sleep as a means of rest long before the development of modern medical science. This study aims to analyze the concept of sleep from the Qur’anic perspective through the approach of i‘jāz ṭibbī (medical miraculousness). The method employed is a library research approach using thematic exegesis (tafsir maudhu‘i) combined with modern scientific analysis. The findings reveal that the Qur’an accurately describes the physiological functions of sleep, including energy restoration, reduction of bodily organ activity, and the importance of a healthy sleep environment. This demonstrates a harmony between divine revelation and modern scientific knowledge.
