Abstract

This study aims to explain the implications of air humidity on determining the beginning of Isha prayer time. This is because of the different times of Syafaq's disappearance at the same location, due to air humidity, which has led to differences of opinion regarding the dip of the Sun. This research is a qualitative study using a field research approach. The primary source is data collected through direct observation with a Sky Quality Meter (SQM) over 30 days in the highlands of Tanjung Heran Village and at Cemara Indah Beach. This study found that air humidity on the coast of Cemara Indah, with a value of <80%, detected the disappearance of Syafaq Ahmar at Dip -18°, which is the same as the dip of the Sun according to the Indonesian Ministry of Religious Affairs. Meanwhile, air humidity of 81-90% resulted in a variable dip in the Sun and, of course, Syafaq disappeared more quickly. In the highlands of Tanjung Heran Village, the air humidity of 95-99% caused Syafaq to be detected as disappearing faster than -18 °, with higher values indicating faster disappearance. Therefore, humidity levels are one of the factors that influence the calculation of the Sun’s Dip to determine the start time of the Isha prayer.

Abstract

This study critically examines the widely circulated claim that a solar eclipse occurred on the day of Ḥusayn ibn ʿAli’s martyrdom during the Karbala tragedy (10 Muḥarram 61 AH / 10 October 680 CE). While the narrative appears in classical sources such as Tārīkh al-Khulafā’ by al-Suyuthi, it has rarely been subjected to rigorous interdisciplinary verification. This research addresses that gap by integrating historical-textual criticism with astronomical data analysis. Using a qualitative library-based approach, the study evaluates the reliability of the narrative through isnād and matn criticism, while cross-referencing it with NASA eclipse records and Stellarium simulations. The findings demonstrate that no solar eclipse occurred or was observable in the region on the stated date, thereby contradicting the historical claim. This suggests that the eclipse narrative functions primarily as a symbolic and theological construct rather than an empirical event. The study contributes to Islamic historiography by emphasizing the importance of methodological integration between traditional scholarship and modern scientific tools, offering a clearer distinction between symbolic religious narratives and historically verifiable facts.
