The purpose of this paper is to investigate three works, namely: “Imam al-Kazim” by Etan Kohlberg from the Encyclopedia of Islam, the section on Imam al-Kazim in Shi‘a Denomination by Dwight Donaldson, and Shi‘ism by Heinz Halm. These three works are fairly comprehensive ones revolving around the Imam’s lifetime—from his birth to his martyrdom.
