The necessity of recognition of some martyrs of Karbala

The event of Karbala was among the most important events in early history of Islam and the martyrs of Karbala were the heroes of this event and hence at the center of concerns. Yet unfortunately in process of time the name and identity of some of them have been forgotten, but in contrast, some names are taken to be the martyrs of Karbala, while they had no role in that event. The main cause of this mistake must be sought in relying on some unreliable sources. This article, resorting critically to some old books and sources, proceeds to examine the identity of five persons claimed to be among the martyrs of Karbala and come to this conclusion that they were not in that battle at all. And as an advice, says that concerning the event of Karbala, beside old and ancient books, we must survey its authenticity.
