Hadith, as one of the sources of Islamic knowledge in its historical course, has suffered damages that affect its credibility. Evaluation of narrations in terms of document, source, text and content is necessary to deal with these plagues and to validate hadith texts. The study of the content of the narrations from the time of the Infallibles (peace be upon them) began with the presentation of the hadith to the Qur'an and Sunnah. From the study of Rijali's works, it appears that one of the documents of Rijali writers in authenticating and weakening the narrators has been the study of the content of their narrations. If this hypothesis is proved, one of the foundations of the knowledge of the rijals, which is the sensibility of the affirmations and weaknesses, will be changed. This article tries to prove this view by discovering phrases from the book Najashi List, which refers to textual and content criticism. This research has been able to take a different look at the knowledge of men in front of the audience and provide the basis for expanding the scope of this knowledge.
