the efficiency of political fiqh

from the very beginning, the political fiqh could not play an efficient role in the social arena. but, now the question is whether the political fiqh can satisfy all the individual, social, spiritual, political, economical, judiciary, and international needs of the time. some have considered most affairs and issues related to the state as reasonable, and as a result, not related to fiqh and inferrence. however, from the definition of fiqh it can be underestood that any thing reasonable and confirmed by sharia can be considered as a religious precept. in other words, since faqihs have included reason and comman usage as the basis for fiqh inferrences, any social and political precept which is based on reason is a fiqh-related issue as well. in addition to reasoning and using quran and traditions for inferring religious precepts, there are other sources such as: eternal evil and expediency, the eternal nature of man, variable and fixed issues, decrees related to the state, development of the objectives of ijtihad, dynamic ijtihad, and the role of time and space in ijtihad.
