Making Some Corrections to Historical Mistakes Committed by Experts on ridjal (transmitters of hadiths) about the Martyrs of Karbala

History is a mirror which reflecs some realities, and is much applicable in science of ridjal (the study of biographies of the transmitters of hadiths) as well as in writing biographies in general. It is impossible to acquire the biographies of transmitters of hadiths properly unless some references are made to works of history. The present article has dealt with the inquiry on some people alleged to be among the martyrs of Karbala, concluding that in some works of Redjal, some people in the camp of the enemies of Imam Hussein have been enumerated among the martyrs; thus, a comprehensive and precise review of history of the Infallible (may peace be upon them), especially that of the Event of Karbala, seems necessary.
