in numerous verses and narrations, the characteristics of religious people are stated under various titles. Numerous studies and writings have also been written in the field of religiousness criteria, where researchers have focused on collecting the characteristics of religious people. By studying the writings, it is found that the principle, basis, and criteria of religiousness have been neglected or have not been considered correctly and accurately. The main issue of the present study, citing Quranic verses and interpretations based on this holy book, is to explain the real meaning of religious people based on Quranic verses and narrations in a descriptive-analytical manner. The research approach of the article is that what is considered a pillar of religiousness is accepting the guardianship of the divine guardian after confessing monotheism and accepting prophethood. If this is important, the category of testing and examination becomes meaningful, but without it, there is no qualification at all to enter the divine test and to advance in rank. In this article, an attempt has been made to examine the aforementioned criterion and its place in the religiosity of an individual and society.
