Maqtal al-Husayn (The Murder of al-Husayn) in Ṭabarani 's Al-Mu'jam Al-Kabir  (great encyclopedia) is of the remaining books of this kind and an ancient source which of course, like other historical and narrative sources, has not been secure of surge of distortions reagarding 'Ashoura which cast doubt on the readers in terms of some material about that event. Although the Hadith style in his books in well-documented and continuous, investigating the narration texts, one can find out that the author, applying certain Akhbari expression, has made effort to show the approach to particularly affect the main purpose of Imam. Other Sunni scholars have adopted this attitude from someone like Ṭabarani. Thus, some of the them like Ibn – e – 'Asakir and Ḍahabi have transmitted these narrations more attractively. Narrations which are mostly about extraordinary and supernatural occurrences following the Imam's martyrdom are considered to be the origin of Ṭabarani's attitude. In spite of some single reports in comparison with other books on history or Hadith, this Maqtal  is in contrast with some certain events or historical narrations and has distorted the status of infallible Imams and their families due to the unreliability of document and text as well as unreasonable differences and oppositions and thus has culminated in untrustable foundation for research among following Shi'ite and Sunni scholars during upcoming centuries.it can be claimed that the Shi'a is the mostly affected school that has benefited from these narrations. In this study, applying library-based method and analytical – critical approach, it has been tried to present some explanation regarding his book and mention some of these distortios and delve into their historical and narrative foundation.
