One of the social anomalies is the promotion of obscenity in the society. In the current era, the media environment has caused this anomaly to be realized in a wide range and at a high speed. Knowledge of the rulings of this issue requires an answer to the question, what are the jurisprudential bases of the ruling on the dissemination of obscenities in the media space, according to Imamiyya jurists? The answer to this question will lead to the introduction and implication of jurisprudential evidence in order to know the basics, with the aim of determining the duties of media users, and determining the executive approach of regulatory bodies. In this article, in a descriptive and analytical way, after explaining the concepts and referring to the meaning of the spread of prostitution, the argument based on jurisprudential evidence has been examined. The verse of Surah Noor has a better meaning than the other two verses. From the hadiths, at least the thing that is used is the sanctity of revealing and declaring sins, especially revealing and declaring the mistakes and sins of a Muslim person. Arguing that some sin is promiscuous in order to prove its sanctity also indicates the certainty of this ruling among jurists. The necessity of the spread of oppression and misguidance in the society and the introduction of corruption as a rational reason, and the disintegration and destruction of societies due to the spread of corruption will also be a rational reason for its prohibition.
