Typology of Narratives of Umar ibn Adhainah in the Book Kāfī and Their Relationship with Salim ibn Qais

Umar ibn Udhainah is important from at least two points of view: firstly, in terms of his jurisprudential traditions, and secondly in terms of his connection with Salim's hadiths. According to the new researches on the edition of Salim's books, Umar ibn Udhainah's attributions on Salim's manuscripts are fake, and they were created in later periods. Now if we assume that these studies are not correct; It is necessary to investigate: Is the narration of the hadiths of Salim's book acceptable by Umar ibn Udhainah, or has it been wrongly attributed to him? Therefore, it is necessary to research the typology of Umar bin Adhainah's narrations in Shiite sources. On the other hand, since most of the hadiths of Umar ibn Udhainah are available in the book Kāfī, the review of the typology of ibn Udhainah's hadiths in this book can be an overview of the typology of his hadiths. The results of the current research show that, if the name of Umar ibn Udhainah includes a historical figure, it is important that his narrations are jurisprudential in about 93.5% of cases, and have nothing to do with the topics of Salim's current books; And if his name includes two historical characters, it means that the narrative approach of these two characters is different. And one had a jurisprudential approach and the other had a theological-historical approach. With the correctness of this assumption, if the documents of some manuscripts of Salim's books copied from ibn Udhainah are not fake; A confusion has occurred between the two characters of Umar bin Adina; This means that the narrative documents of the famous Umar ibn Udhainah were mistakenly included in the manuscripts of Salim's book.
