عنوان مقاله [English]
The book Scale of Moderation (Mizan al-I’tidal) written by Shams al-Din Zahabi is one of the most important Sunni rijali main sources regarding the weak narrators. The present study has been compiled with a descriptive-analytical method and seeks to examine the Zahabi’s commitment in this book to the criteria of critique and judgment (jarh wa ta’dil). Contrary to his claim in the introduction to the book, he does not seem to be fair and has a double standard towards certain narrators. In assessing the credibility of the narrators, he has involved religious tendencies and treated the Shiite narrators harshly, but he has used the method of tolerance towards the Sunni narrators.
