Ethical concepts are divided into value concepts and obligation concepts in the philosophy of ethics. Ethical obligation concepts refer to the concepts of ethical “ dos” and “ don’ ts” in this research work. This study seeks to find out how and with which method these two ethical concepts can be inferred and extracted from the verses of the Quran using the descriptive-analytical method. Since ethical obligation concepts are among the most widely used ethical concepts in the Quran, and, on the other hand, without knowing the ways of expressing ethical concepts, it is not possible to know and benefit from the moral teachings of the Quran in a scientific way, and since there is a lack of method-oriented research in this field, these concepts need to be examined. The findings of this endeavor revealed that the ethical “ dos” of the Quran are expressed in the four styles of “ orders and demands” , “ duties and responsibilities” , “ advice and recommendations” and “ encouragements and persuasions” , and the ethical “ don’ ts” of the Quran are expressed in the four styles of “ restraints and prohibitions” , “ threats and warnings” , “ reprimands and rebukes” and “ expressions of surprise and remorse” .
