Al-Hilal: Journal of Islamic Astronomy
Al-Hilal Journal is a scientific journal published in April and October per year by the Islamic Astronomy at the Faculty of Sharia and Law, Universitas Islam Negeri (UIN) Walisongo, Semarang colaboration with Asosisasi Dosen Falak Indonesia (ADFI). Articles published in this journal are the results of empirical research in Islamic Astronomy (such as qibla, salat times, Islamic Calendar, Eclipse and others), and its approaching on other area studies (mathematics, physics, astrophysics, social, politics, anthropology, ethnography and others). This journal has specifications as a medium of publication and communication of Islamic Astronomy ideas derived from theoretical and analytical studies, as well as research results in the field of both natural and social science. The editor hopes that writers, researchers and legal experts will contribute in this journal.

<![CDATA[The calculation of prayer times in Bali and Banyuwangi Regency often needs to be clarified. Hasib suggests Bali's prayer time calculations could refer to those in Banyuwangi due to their close astronomical coordinates. While Bali uses the Central Indonesian Time Zone (WITA, GMT+8), Banyuwangi adopts the Western Indonesian Time Zone (WIB, GMT+7). This discrepancy arises despite the proximity of their locations, reflecting government decisions based on international considerations, especially after Bali was reassigned from WIB to WITA through Presidential Decree No. 41 of 1987. This library research uses qualitative methods such as documentation and descriptive analysis. It shows that the differences in prayer time calculations between Bali and Banyuwangi are minimal, often just a matter of seconds, mainly if there is an error in inputting Ephemeris data. However, such errors have no significant impact as long as the date remains consistent and time zone corrections adhere to official regulations.]]>

<![CDATA[There are a lot of holy texts in Islam, like Al-Qur'an and Hadith, discussing the Sun that will rise in the West. However, a study has yet to be conducted to explain this phenomenon from a scientific point of view. It creates several issues, such as the explanation of the Sun rising from the West from the point of view of religion and scientific terms, nor the way to prove and predict the time of this phenomenon. This research was compiled using a qualitative analysis method with a case study approach. This approach limits its analysis tools to one specific case. This study used an analysis of the Sun's azimuth shift at the time of the Equinox to prove the possibility of sunrise from the West. With this method, it is discovered that in a religious view, the rising Sun from the West is seen as a real event and will occur physically. Meanwhile, science is to explain how possible scenarios can cause this phenomenon to occur. In addition, an analysis of the shift in the Sun's rising point concerning the azimuth of the Sun at the time of Equinox cannot prove and cannot predict when the Sun will rise from the West, which is a sign of doomsday.]]>

<![CDATA[Astronomy is the oldest science discovered. Therefore, the discussion of who the first inventor of astronomy was is interesting to explore. Some literature states that the Prophet Idrīs was the first person to know astronomy. However, there is also an opinion that the Prophet Unusy had known astronomy long before the Prophet Idrīs was born. To discover who invented astronomy, we need to trace who the Prophet Idrīs was when viewed from the perspective of the Bible (Old Testament and New Testament) and the Qur'an. Through a historical approach and analytical descriptive method, this article explains the results of a study related to the biography of the Prophet Idrīs and his genealogy according to the Bible and the Qur'an, as well as several opinions of astronomy experts who confirm the Prophet Idrīs as the inventor of astronomy.]]>

<![CDATA[This study explores the interpretation of false dawn (fajr kādhib) and true dawn (fajr ṣādiq) in al-Shāfi’ī fiqh texts through the lenses of hadith and astronomy. It compares classical definitions by al-Rāfi'ī and al-Nawawī with contemporary scientific and hadith-based perspectives. Using documentation and descriptive-critical analysis, the research finds that fajr kādhib is described as vertical light (mustathil) resembling a wolf's tail, appearing briefly and vanishing. In contrast, fajr ṣādiq is horizontal light (mustaṭīr) spreading across the horizon, gradually brightening. From a hadith perspective, this aligns with al-mu'taridh (true dawn) and al-mustathil (false dawn). Astronomically, fajr kādhib matches zodiacal light, which doesn’t disappear, and fajr ṣādiq corresponds to sunlight scattering. Thus, the disappearance of fajr kādhib, as described in classical texts, lacks modern scientific support.]]>

<![CDATA[This study analyzes the use of radio telescopes in rukyat al-hilāl observations from the perspective of science and fiqh. In modern astronomy, radio telescopes have become essential for observing celestial objects emitting radio signals, including planets, stars, and other cosmic phenomena. However, its use in observing the Hilāl as a marker of the beginning of the Islamic month is still debated, especially from the perspective of Islamic law (fiqh). This study uses a literature study method with a qualitative descriptive approach. The study's results indicate that this technology is not scientifically suitable for detecting the hilāl and determining the beginning of the Hijri month. Meanwhile, from a fiqh perspective, radio telescopes cannot be considered valid for observing the hilāl in determining the beginning of the Hijri month. Observing the hilāl in determining the beginning of the Hijri month requires a visual vision of the crescent moon object visible after sunset as a sign of the start of the new month in the Hijri calendar.]]>

<![CDATA[This article examines the paradigm shift in determining the start of the Islamic month, driven by advancements in science and technology. Initially, Muslims relied on moon sighting (rukyat al-hilāl), but the mastery of mathematics and astronomy led some to adopt calculations (ḥisāb). The study focuses on the differing approaches of the Nahdlatul Ulama (NU) Baḥṣul Masāil and the Muhammadiyah Tarjih forum. With the advent of computers and the internet, Muhammadiyah embraced ḥisāb and the global Islamic calendar. Meanwhile, NU integrates traditional rukyat with modern tools like mathematics, computers, and photographic technology while maintaining a regional calendar. These differences highlight Muhammadiyah’s modernist paradigm and NU’s eclectic approach, blending tradition with modernity.]]>
