An Examination of Jurisprudential Principle of Deceiving the Uninformed Person as Harram

Deceiving the Uninformed Person (Taqrir Jahil) is forbidden, either with the concealment of the truth or expressing something against it - if specific conditions exist and this is one of the famous jurisprudential principles that has been mentioned and cited in various cases and even in the novel issues of jurisprudence. However, But all its aspects have not been elaborated in a centralized independent work. This paper, for the first time, through descriptive-analytical research methodologies and library documents, examines and clarifies the contents, argument of the jurisprudence (Qur'anic verses, narrations, reason, jurisprudential rules and the application of some arguments) and the scope of this principle so that the jurists' attention can be taken seriously in jurisprudential inference. Some jurisprudential principles, such as principle of Tasbib (wasting) as forbidden, the necessity of uninformed person in giving, the necessity of guidance of the uninformed person, the denial of Gharar (uncertainty), the concealment of the truth and the relying on sin, can be evidence or proof for the validity of this jurisprudential principle. This is a propositional rule that includes the general jurisprudential ruling and covers all or most of the jurisprudential topics and is applicable to minor cases. Therefore, in some cases, not taking exception will not disrupt its accuracy or even its generality since all the principles including jurisprudential and non- jurisprudential take exceptions in some cases.
