Abstract

The community experiences both positive and negative consequences as a response of Qibla direction calibration, particularly in the ancient mosque, an ancestral heritage mosque whose authenticity must be preserved. One of them is the Air Tiris Great Mosque in Kampar, which must be preserved from the initial stages of growth because it is a tourist destination and an item of cultural heritage. This article aims to verify the calibration of the Qibla direction of the oldest mosque in Kampar and the techniques employed by earlier scholars in measuring their Qibla direction using field investigations and data sources from observations and interviews. This article concludes that the Qibla direction is accurate and correct, the Air Tiris Grand Mosque was established in 1901, and that it has never undergone renovation. When the global Qibla direction was wrapped in religious intuition, the cleric at the time, Datuk Engku Mudo Songkal, used the sun's shadow to bring religious intuition and scientific truth together.

Abstract

Accuracy in facing the Qibla is an essential part of performing prayers. This vital value is evident when many mosques are built in public places. This article is qualitative with field data sources, namely coordinate points at the Jemursari Islamic Hospital mosque, Surabaya Islamic Hospital, and Al-Irsyad Hospital Surabaya. Once collected, the data was analyzed using three methods for calculating Qibla direction, namely Spherical Trigonometry, Jean Meeus, and Google Qibla Finder. This article found that the three methods obtained the same results at the Jemursari Islamic Hospital at 294°3'5", at the Surabaya Islamic Hospital at 294° 3'6", and at the Al-Irsyad Surabaya Hospital at 294°3'5 ". However, there is a difference between calculations and field measurements of 2°–7°, including within the Qibla deviation tolerance. It can be concluded that these three methods can accurately determine the Qibla direction in various locations. However, re-checking is required if the measurements exceed the tolerance limits.

Abstract

The Aboge calendar system is still used today by several traditional Javanese community groups. One community that still uses this calendar system is the Samin Klopoduwur Community, Blora. In contrast to Aboge users who use Aboge to determine the start of the month, this community uses the Aboge calendar as a daily calendar. This research will focus on the existence and factors that encourage the Samin Klopoduwur community to maintain the Aboge Islamic Javanese calendar system. This research is qualitative research using a field approach. Data access was carried out by conducting in-depth interviews, observations and documentation, all of which were analyzed descriptively and analytically. The research results show that apart from being a daily calendar, they also use the Javanese Islamic Aboge calendar system as a guide to determine the days of religious ceremonies.

Abstract

Astronomy has developed in India since prehistoric times. However, astronomy’s first work appeared during the Vedanga Jyotisa era, written by Lagadha, the oldest literary book in India. Using qualitative methods with a library research approach, it was found that Indian astronomers researched Astronomy and wrote books. One of the books that first made Muslim scientists interested in the world of astronomy was the book Brāhmasphuṭasiddhānta, which was translated into Arabic by Al-Fazari (d. 796 AD) during the Caliphate of Al-Manṣūr from the Abbasid dynasty. Al-Fazari (d. 796 AD) became the first Muslim astronomer to compile Zij, with his calculations converted into the Hijri Calendar. After Al-Fazari (d. 796 AD) collected this Zij, other Zijs were born, which became the forerunners for the composition of the epimeris and other counts. Around the beginning of the 11th century, Al-Biruni (973-1048 AD) spread da'wah to India and introduced the study of Islamic astronomy in India.

Abstract

The five daily prayer times in the al-Falaqiyah text are determined using rubū’ mujayyab, except for the Maghrib prayer time. It is stated in the text that the time for Maghrib is six o'clock without further information being given. This method contradicts the current method of determining the beginning of prayer times. By using qualitative research with literature study, this paper explores further the basis for calculations and implementation of the methods used in the al-Falaqiyyah text. By using descriptive analysis, it was found that the six o'clock provisions for Maghrib prayers in the text are approximate. After comparisons were made, there was also a difference of 3 to 7 minutes in the Maghrib time in the manuscript with the Maghrib time calculation using rubū’ mujayyab.

Abstract

The eclipse prayer, considered Sunnah Muakkad, presents different points of view among the ulama. Most jurists believe these prayers are prohibited during haram times (taḥrīm) because the ḥadīth applies to all prayers. It is different from al-Shāfi'ī who allows eclipse prayers at any time, even during taḥrīm. Since most Indonesian people adhere to the al-Shāfi'ī school of thought, understanding the basis of its ijtihād is essential. With a qualitative method, this literature article uses a descriptive-analytical method, with the primary source being the book al-Umm. This article produces two main findings. First, al-Shāfi'ī justifies the eclipse prayer during taḥrīm because of the general nature of the ḥadīth restrictions and the particular reason for the eclipse prayer. Second, the legal reasoning uses qiyās, aligning missed prayers with valid reasons at taḥrīm times.
AHMAD MARZUQI AL-BĀTĀWĪ’S THOUGHTS IN FAḌL AL-RAḤMĀN BOOK AND ITS IMPLEMENTATION ON DETERMINING ISLAMIC CALENDAR IN INDONESIA Yaqin, Ahmad Ainul; Rohman, Khabib Syaikhu; Faza, Ricka Ulfatul

Abstract

Criteria for the visibility of the new moon have been initiated by Betawi ulama, one of which is found in the book Faḍl al-Raḥmān by Ahmad Marzuqi al-Bātāwī. Ahmad Marzuqi's criteria are very different from those used by the Indonesian Ministry of Religion, giving rise to several differences. Using literature research and interviews as a data collection method, this paper finds that Ahmad Marzuqi al-Bātāwī's thoughts in the book Faḍl al-Raḥmān state that the minimum limit for imkān al-rukyah is 7° without using a telescope. This idea of imkān al-rukyah is still currently being implemented by the al-Marzūqiyyah congregation in Cipinang Muara, East Jakarta, in determining the start of the lunar month so that if the height of the new moon is less than 7° it causes differences with the government.

Abstract

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.

Abstract

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.

Abstract

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.
