Types of narrators based on adjustment

In rehearsing the sources of Rijalians, we see adjustment and weakening of a many narrators. It seems that narrators have different types in the view of the Rijalites and the early Mohaddesin (until the fifth century AH). This research tries to find that if it was necessity for the old Rijalites to adjusting and weakening all the narrators, or some of the narrators have a priority about that? This research suggests that in the Rijalites books we see three groups of narratives: narrators for oral hadith, narrators owner of hadith books, and narrators of the ways to hadith books. The Rijalians have less tried to adjusting the narrators of oral hadith and narrators of the ways, and have paid more attention to discussing the classes of these two categories. Also, the weakness for the narrators of the ways, provided that they are well-known to one way of one work, or the great hadith narrators have trusted them and have narrated many hadith from them in the field of the requirements, has no harm to their hadith. But Rijalians have paid a special attention in the area of adjustment to the narrators owner book and the authors.
