imam mohammad ghazzali and theory of correctness of all opinions in idjtihad

contrary to majority of islamic jurists, those who believe in singularity of reality and a certain rule in disagreement cases, in opinion of some of the scholars, the truth and the rule is plural and all of the jurist(modjtahedin) are just. imam mohammad ghazzali is one of these scholars. in his opinion, the theory of proscription (takteah) is incorrect and contradictory. with the exception of cases included in definitive evidences, the modjtahid’s conjecture or belief is god’s rule too. there is no real or certain rule before his jurisprudential reasoning. ghazzali’s arguments, in summary, are: rational and islamic evidence, relativity of circumstance, individual interests, ancestor’s custom, contradiction and weak arguments of the theory of proscription
