With respent to the objectives of an Islamic state, Mohaghegh Tusi observes three major functions for a state: the explanation of divine commands (iftah), judgment and adjudication, and policy making. The welfare of the Muslems, in his point of view, is an element which has a central role in accomplishing these functions and determines their limitations. The specific functions of a state, resulting from the above-mentioned major functions, include appointing governors, emirs, and judges, executing the divine commands, defending the rights of citizens, building the financial infrastructure, and confronting the causes of economic crises. The last issue concerns the amount of authority a successor of the Twelfth Imam may have during the Absence Era. Resorting to traditions and reasoning, Tusi is to transfer all the authority of the Imam to a faghih, a jurisprudent who meets all the requirements.
