Of course...
Of course, we believe that by the grace and blessing of God, a time will come when through Hadhrat Wali al-‘Asr (may Allah expedite his glorious advent) the ideal Islamic and divine society will be established. It must be noted, however, that even that society will not be totally free from violation of law, in addition to the fact that it will also not persist forever.
It is even mentioned in some traditions that some will revolt against the Imam of the Time (may Allah expedite his glorious advent) and cause his martyrdom. It cannot even be expected therefore that during the rule of Hadhrat Mahdi ( ‘a ) society will become totally ideal and desirable and completely devoid of sin and transgression.
Of course, the structure of that government and his exercise of authority will be such that no oppression and corruption will continue unanswered, the implementation of justice will be all-encompassing, and violations in social and public life will diminish, but they will not be uprooted in total. This is because man will not acquire an angelic nature. As in the past, there will always be room for insolence, sin, violation, and transgression in him.
Thus, paying attention to reality prompts us to acknowledge the exigency of state and government. One must mingle with people and observe their conduct and behavior—see how even good and meritorious individuals commit sins and offences sometimes.
Naturally, in order to deal with and prevent violations, sound and necessary laws must be implemented (and I dealt with the necessity of codifying and enacting them), for if laws for implementation and execution in society are codified, they must have implementers and executive guarantors. The fundamental reason for having a government is to guarantee the implementation of laws at all levels of society. This is the point we are presently concerned with.
God willing, we shall deal with the duties and prerogatives of government, its organizational structure and other related issues in future discussions. The exigency and source of power A government possessing brute force and sufficient power must be established so as to manage affairs, implement laws, defend beliefs and values, maintain internal and external security, prevent violations, thwart conspiracy, and hamper external aggression to Islamic society.
For this reason, in political philosophy the concept of power is pivotal. In fact, some have even described “politics” as “the science of power”.
