Reading the Viewpoint of Sayyed Ahmad Khansari about Istishab based on Jami al-Madarek Book

Undoubtedly, knowing the Usuli opinions of each jurist plays a significant role in understanding his jurisprudential approach. Ayatollah Sayyed Ahmad Khansari, the author of the precious book Jami al-Madarak, is one of the great contemporary jurists. Despite his numerous jurisprudential and theological books, he has left no Usuli book that may be consulted in order to identify his Usuli views. His Usuli views should be investigated in his jurisprudential books and among individual precepts. Among the practical pinciples, Istishab (the principle of continuity of the previous state) has a special position either in terms of its widespread examples or because of being one of the Usul e Muhreze (principles that declare the duty by taking into account the reality). In this paper, by referring to the jurisprudential book Jami al-Madarak, the authors seek to realize his opinion about the nature and characteristics of Istishab. By taking this paper as a model, one may perceive his Usuli views and discover the missing pieces of his Usul al Fiqh.
