The essay comprises six parts. The author first mentions the reasons for following a religious authority and tries to prove them referring to rational and Traditional reasons. On the other hand, he brings and answers the reasons which do not support following. Then in the second part, he asks whether one with the ability of deduction can follow someone else or not, a question to which the author responses he can follow in some assumptions. The third part, according to the author, covers "Motejazi" jurist who can give decrees just in some parts of jurisprudence, and can conditionally follow his own decree, although the conditions are difficult to be achieved. In the fourth part he notes that jurists who have not achieved the level of being "best-aware" are not permitted to give decrees. Next, he suggests that how the rules being deducted by the jurist would be enforced for the follower. And at last, he discusses the permission to follow an older decree, while deducting a new different decree, without any due responsibility.
