Among the discussions on Imamate is that of Imam’s knowledge and its knowledge. This has been a constant source of discussion throughout the history among Shiite scholars, with numerous books having been composed in this respect, among them narrative literature on the Minor Occultation in the two books Basā’ir alـDarajātby Saffār and AlـHujjah in Kalini’s AlـKāfīcollection. The examination of the views of its authors has an important role in the intellectual study of Qom’s hadith school while clarifying the Companions’ impression of narrations on this topic. The extent of Imam’s knowledge is a controversial discussion on Imamate in the Muslim nation (ummah) and the followers of Shiism. Saffâr and Kalini, inheritors of Qom’s hadith school, have collected narrations on this topic to introduce Imam’s knowledge in the realm of Creation and preordinations. Knowledge of facts of the past, events of the present and preordinations of the future constitutes a large collection of truths that are compiled in Mohammad’s Household’s knowledge collection. The present research rejects the view of some people on the difference between the two books, AlـKāfiand Basā’ir alـDarajāt, while emphasizing that not only kolaini did not give up the discourse of Qom’s hadith school, but he also provided them systematically in a new form. An attempt has been made in the present research to provide a selection of narrations relating to this discussion based on the objects of knowledge. This selection was made of the large number of tradition on knowledge and provides a single criterion for comparing the chapters and narrations of the two books.
