Hujjat Allah al-Baligha

Hujjat Allah al-Baligha (Arabic: حجة الله البالغة, lit. 'The Conclusive Argument from God') is an 18th-century Islamic socio-theological work written by Shah Waliullah Dehlawi. Widely regarded as his magnum opus, it is a unique work of its kind, combining elements of history, philosophy, law, theology, and psychology. The book seeks to explain the underlying purposes and meanings of Islamic laws, rituals, and traditions by integrating mystical, rational, and textual approaches. Shah Waliullah interprets the sharia as a set of divine injunctions consistent with human nature and innate intuition. He viewed prophetic reform as an effort to awaken and actualize the moral and social potential inherent in human societies. The structure and approach of the work bear similarities to al-Ghazali's The Revival of the Religious Sciences.
