possibility or impossibility of inferring political precepts from the quran

contemplation in devine books to obtain earthly rules and regulations has given rise to contradictory controversies. in islam there is a disagreement between the traditionists and the rationalists. the traditionists claim that the quran is addressed only to the prophet and the imams, who are innocent. therefore, common people do not have the ability to infer precepts from the quran, being liable to commit sins. on the other hand, rationalists believe that the quran has been sent to guide mankind, so jurisprudents are able to infer individual and social precepts from the holy quran.
