The Fiqh of Ahlul Bayt refers to the comprehensive body of Islamic jurisprudence derived from the teachings and interpretations of the Household of the Prophet Muhammad (peace be upon him and his progeny). This school of thought, primarily followed by Shia Muslims, emphasizes the infallible guidance of the Imams from the Ahlul Bayt, believing them to be the authoritative interpreters of the Quran and the Sunnah after the Prophet. It encompasses a vast array of religious laws and principles governing all aspects of life, from ritual worship and personal conduct to social dealings and political governance, all rooted in the pristine knowledge and wisdom transmitted through this sacred lineage.
