We do not find a philosophical explanation of the entire legal system of Islam before Shah Wali Allah. Therefore, according to our knowledge, Hujjat Allah al-Balighah is the first work dealing with this subject so extensively and comprehensively and with an intense emphasis which are all its own. Further, most of its subjects and themes are hitherto unparallelled. It is an exclusive distinction of Shah Wali Allah that he combined the varied discussions on phi- losophy, scholastics, Qur'an. Hadith, and Tasawwuf with his own forceful contemplation, observation and dialectical vigour
