Aqidah refers to the set of beliefs and doctrines that form the foundation of the Islamic faith. It encompasses the core tenets that every Muslim is expected to accept, including the belief in Allah (God), the prophets, the holy books, the angels, the Day of Judgment, and divine predestination. These beliefs guide the spiritual and moral conduct of Muslims.
The study of Aqidah is essential for understanding the Islamic worldview and the relationship between humans and the divine. Scholars often categorize Aqidah into different schools of thought, such as Ash'ari and Maturidi, which interpret these beliefs in various ways while maintaining the core principles of Islam.
