State of Jebal or non-Arab Iraq enjoys a specific status in the history of Shi’ism; it includes the central and
western regions of Iran. This state was in adjacency of the first and main center of Shi’ism, Kufeh; it had been inhabited
by a large number of Shiites; and, Shi’ism first spread to this state from Kufeh and spread to other oriental Islamic cities.
Esfahan, Aveh, Qom, Rey, Qazvin, Kermanshah, and Hamadan were its important cities. Hamedan, which is the subject of
this study, is one of the important cities of Iran in early Islamic period; its neighborhood with Iraq has further contributed
to its importance. The main question is that what is the role of jurisprudents and the Hamadani companions of Imams in
development of Shi’ism in Hamadan. It is concluded that after attorneys of Imams, jurisprudents and scholars of
Hamadan have significant role in advent and development of Shi’ism in Hamadan. This research is concerned with the
first ten centuries AH and Hamadan of those times; length of Hamadan was from Si Shahr to Karaj, and its width was
extended from Asadabad to Saveh.
