Bandar Seri Begawan – Members of the Astronomical Society of Brunei Darussalam were at Bukit Agok, Tutong, for a practical session to look for the new crescent moon (hilal ~11 hour old) this evening of Sunday, May 5th in anticipation of the beginning of the holy month of Ramadan.
Members had the opportunities to learn setting up telescopes properly, scopes alignment to the sun or other bright objects, photographing and tracking the new moon. The western sky was pretty clear at sunset, and a sunspot was also visible on the sun.
There are various methods used to determine the arrival of Ramadan (fasting) and Syawal in South East Asia. Malaysia and Indonesia use the rukyah (sighting of the moon) and hisab (mathematical calculations), Singapore uses the hisab while Brunei only uses the rukyah method. These differences are due to the different basis for using a certain method to determine the arrival of Ramadan and Syawal. The basis here refers to religious references and forms of istidlal (inferences). The question is, what religious references are used to substantiate the adoption of the rukyah method in Brunei? What is their form of istidlal based on the religious references? To answer all these questions this study has two objectives. Firstly, it intends to determine the religious references that act as the basis for using the rukyah method in Brunei. Secondly, to analyse the different forms of istidlal based on the religious references. In order to achieve these objectives, this qualitative study used library research and expert interview methods for collecting data. All the data were analysed using the content analysis method. Lastly, this study concluded that religious references from the al-Qur’an and Hadith used as a basis for applying the rukyah method in Brunei is similar to the religious references used as a basis for applying rukyah and hisab in other South East Asian countries. The only difference is the various forms of istidlal.
Bandar Seri Begawan – The official new moon sighting date to determine the beginning Ramadan 1436H will be on Tuesday afternoon, June 16. The sightings will be carried out in several vantage hills across the country by government officials from the Ministry of Religious Affairs and Survey Department.
The following is the astronomical calculation of the moon for Bandar Seri Begawan, Brunei, on the day of Syaaban 29,1436H corresponding to June 16, 2015
1. Sun sets at 18:32 (Local Time)
2. The moon sets at 18:18.
