In the context of Islam, falak and syarie are two terms commonly used in religious studies, especially regarding the determination of worship times such as prayer and fasting. The following is a brief explanation:
Falak science refers to Islamic astronomy, the study of the movements of celestial bodies (such as the sun, moon and stars) for the purpose of determining worship times.
Syarie means something that is related to Islamic law (Shariah). It refers to the laws and rulings established in Islam based on the Quran, hadith, ijma’, and qiyas.
Falak science supports the practical aspects of worship (such as timing and direction), while the term syarie refers to the legal dimension and rulings that guide daily practice for Muslims.
