The determination of right from wrong was gradually becoming difficult and complicated for Hadith science researchers and scholars upon getting distant from the era of Hadith issuance. This same issue urged the thinkers and researchers of the HADITH area to explore the biographies of the HADITH narrators so that they might gain an insight over the validity of their speeches. Some heightened the importance of such cognition to the extent that the determination of the authentic from weak HADITH without scrutiny was deemed improbable. Therefore, biographical evaluation became twice as much important with the pass of time. “Hamad Ibn Hassan” was one of the famous Shiite narrators whose biography has been most frequently evaluated by the scientists of the field. Since he has been a disciple of Imam Sadeq (PBUH), Imam Kazem (PBUH) and Imam Reza (PBUH) and there are many narrations cited from him and his narrations have been the foundations of many other Shiite Hadith narrators, the precise knowledge of his authenticity or otherwise can be followed by validation or invalidation of a large and robust part of Shiite Hadith system. The issue is well illustrative of the importance and necessity of the subject with which the current research paper has dealt. The present study, meanwhile presenting accurate information about Hamad’s name and surname, demonstrates his reliability and validity. The study has been conducted based on a library research method.
