The texts dedicated to the written record of the Ashura narration fall into two general categories and First, the historical books that have dealt with the incident of Karbala as one of the events while dealing with the events, such as Tabari's history, Jacob's history and other books that have reached us under the title of history. The other category is the texts that were specially written to record the events of Karbala and did not mention any other events. Mazandarani's Fada'i poems, Maqtal, is placed in this category, which has a literary difference and distinction from other Muqatils in terms of format. Fadaei Mazandarani admitted in the preface he wrote on the poem "Maqtal Manzoom" that he documented his narrative with written sources, although weak. This speech prompted the author to examine the death of Mazandarani's devotional poems with the approach of source criticism Therefore, the martyrdom of Abbas bin Ali was selected as a sample and the main narrations about it were examined and measured with the Fadai narration. In this study, it was found that Fadaei Mazandarani took his narration from Toreyhi's narration in the selection and applied two major changes: deletion of statements, expansion of state.
