The article aims to study the public decency regulation of Saudi Arabia. As we know, Saudi society has already provided a mechanism to regulate the social order or good manners by religious precepts. It seems that the main reason for the enactment of this regulation is to be a measure to avoid harming traditions, emotions, and customs. The enactment of the public decency regulation of the Saudi Arabia adopts only fine system in terms of edification rather than punishment for criminals and imposes the highest fines for indecent behavior, which can be seen as an effort to protect areas related to the performance due to the influx of foreign culture. Originally in Islam, the act of destroying public order or public morals was a personal act, and the judge was able to judge according to his own conscience ( تعزير , Ta’zīr). Along with the implementation of this regulation, Saudi society is now expected to change flexibly from a rigid atmosphere by placing the public sector in the realm of misdemeanors.
