One of the most important documents of the prohibitions is the principle of precaution, which has been considered as a reference for marriage since ancient times. In the approximation of the principle of precaution in Foruj, apart from verses and narrations, one of the evidences that can be documented is a rule that researcher Na'ini invented in some forms of relying on the general in cases of doubts about the validity and has applied it in cases of jurisprudential branches.<br /><br />In this article, which was conducted in the style of library research, after explaining and explaining this rule and the applicable jurisprudential documents and branches, its criticisms are expressed and examined and finally it is concluded that the said rule does not have reliable evidence and documentation, and the claim of customary association in this regard cannot be proven either.
