The Hadith collection of Mohammad Ibn Ya’qub Kolaini, called Kafi, is one of the most important Hadith collections of Twelve-Imam Shiites. Some Orientalists have studied the differences of this work from two other Shiite Hadith collections-Mahasin and Basa’irad-Darajat-and concluded that Kafi is, in respect to the content, similar to the other works which represent the exaggeration (Qolow) in Qom, but since it has addressed the rationalist Shiites of Baghdad, it is moderate in its choice of hadiths and their arrangement. This paper seeks to examine this thesis and challenges the idea that Baghdad Shiites do not credit narrations, due to their radical rationalism. I believe that in his valuable work, Kolaini sought to collect the narrative heritage of Shiites in a traditional way, and he has carried out this task in Ray, not in Baghdad.
