Prophetic Guidance on Prayer Times: Integrating Hadith and Modern Astronomical Calculations

Panduan Kenabian tentang Waktu Solat: Mengintegrasikan Hadis dan Pengiraan Astronomi Moden

Abstract

Prayer (ṣalāh) times occupy a central position in Islamic worship, as the five daily prayers are prescribed at specific times determined by natural phenomena and guided by divine revelation. The Qur’an emphasizes the observance of prayer within fixed times, while the Sunnah of Prophet Muhammad (peace be upon him) provides detailed practical guidance for identifying these periods through observable signs such as dawn, sunrise, shadow length, sunset, and the disappearance of twilight. Historically, Muslims relied on direct observation of celestial changes to determine prayer timings, and Prophetic guidance served as the foundational framework for both individual worship and communal religious administration. With the advancement of science and technology, modern astronomical calculations have become increasingly important in determining precise prayer schedules. Mathematical models based on solar movement, geographic coordinates, atmospheric refraction, and twilight angles now enable highly accurate prayer time calculations for different regions of the world. These methods are especially valuable in urban environments, regions with extreme latitudes, and contexts where direct observation is difficult. Despite these advancements, variations remain among calculation methods adopted by Islamic institutions, creating debates regarding the balance between traditional observational approaches and computational precision. This study aims to explore how Prophetic guidance on prayer times can be effectively integrated with modern astronomical calculations in order to develop accurate and religiously sound prayer time systems. The research adopts a qualitative methodology and content analysis of classical Hadith sources, juristic discussions, and contemporary scholarly studies on Islamic astronomy and digital prayer-time systems. Relevant sources were selected from peer-reviewed journals, classical texts, and official institutional guidelines. The findings indicate that there is substantial compatibility between Hadith descriptions of prayer times and modern astronomical data. Prophetic signs provide the normative principles, while astronomical calculations offer operational precision and global applicability. This integration has improved consistency in prayer schedules, facilitated digital applications, and strengthened worship management. However, challenges persist, including differing juristic interpretations, varying twilight-angle standards, regional environmental factors, and overreliance on unverified mobile applications. The study concludes that a balanced integration of Hadith-based guidance and scientific calculation provides the most reliable framework for contemporary prayer time determination while preserving the spiritual and legal objectives of Islamic worship.
