Imam Khomeini, as a founder and reviver of the contemporary doctrine of religious democracy, and as the most influential Shia cleric, could establish a type of government based on the theory of Islamic jurisprudence that possessed the deep-rooted Shia concepts. The Islamic Revolution under his leadership was a great movement with unique intellectual and practical aspects that trespassed all borders of political and religious thinking. This has been always paid due attention by many thinkers and researchers who were interested in analyzing his thoughts and exploring his stances in various periods vis-à-vis important developments and incidents. In the meantime, understanding the codes of conduct and political thoughts of such personalities as Imam Khomeini who have passed away, and consequently discernment of their probable stances on current developments, require review and systematic and methodical analysis of their opinions. This paper is an attempt to adopt a methodical approach to study Imam Khomeini’s manners, code of conduct and political thought, explaining the outstanding points and unique qualities that distinguish him from other great contemporary Shia scholars, to codify a method for reviewing his opinions and his political stances, including his last will. This is to open a way to conduct an in-depth study of his illuminated code of conduct and his thoughts.
