This research has presented the conceptual model of "sexual chastity" by identifying and examining the components of sexual chastity and factors of the model. This work is qualitative and fundamental research that has been described and analyzed in the section of presenting a conceptual model based on the theory derived from data. For this purpose, 7 concepts related to chastity were identified from the verses of the Qur'an and explained with a coherent approach. By providing a model, the role of some of these concepts in explaining sexual chastity was confirmed. From a total of 345 verses of the Qur'an on sexual issues, 50 verses that were directly related to sexual chastity were selected, and then, with open coding, a total of 49 codes were identified. In the pivotal coding stage, the data were categorized into 19 elements and key concepts, and in the selective code stage, these concepts were subdivided into four template factors. The factors of the model including the components of the focal category, contexts, and causes, strategic concepts, and consequences of sexual chastity were identified and at the end, during this process, the conceptual model of sexual chastity has been designed with a Quranic approach.
