Hadith studies focus on the collection, analysis, and interpretation of the sayings and actions of the Prophet Muhammad. These records, known as Hadith, serve as a crucial source of guidance for Muslims, complementing the Quran in understanding Islamic teachings and law. Scholars in Hadith studies evaluate the authenticity of these texts through a rigorous process called Isnad, which examines the chain of narrators. This ensures that the teachings attributed to Muhammad are reliable and accurately transmitted, playing a vital role in shaping Islamic beliefs and practices.
