A Distortion in Thaqalain Tradition critically examines the historical and theological implications of alleged distortions within the Thaqalain tradition—a foundational concept in Shia Islam which asserts the Prophet Muhammad (PBUH) placed significant emphasis on holding fast to the Quran and his family (Ahl al-Bayt) as twin sources of guidance. This book provides an in-depth analysis of the origins, transmission, and interpretation of the Thaqalain tradition, exploring how different historical contexts and sectarian perspectives have influenced its understanding and acceptance. The author investigates the discrepancies and distortions that have emerged over time, offering insights into how these variations affect the broader Islamic discourse. Through a detailed examination of primary sources, historical records, and scholarly interpretations, A Distortion in Thaqalain Tradition aims to clarify the authentic teachings of the Prophet Muhammad and their implications for Islamic beliefs and practices. This book is essential for those interested in Islamic theology, history, and the ongoing debates surrounding the integrity of prophetic traditions.
