Fighting with non-Muslims and its conditions is one of the issues that have always been discussed in the interpretations. Commentators differ on who is the warrior and what is the reason for the necessity of war with non-Muslims. This research tries to investigate these views according to verse 193 of Al-Baqara Surah by description, explanation and critical analysis. In the meantime, the neglect of the Qur'an moral theory in the interpretation views has caused unjustified opinions. The purpose of the research is to identify the Qur'an ethical theory   in normative ethics in order to get a better understanding of the mentioned verse.  The results show that the moral theory of the Qur'an is close to the deontological ethics. According to this approach, harming non- warrior is morally objectionable, and a non-Muslim should not be killed for his wrong belief. Also, according to the Al-Baqarah Surah, verses 190 to 193, and its semantics, the word “sedition " indicates the destructive actions of non-Muslims as well as the persecution of Muslims, and other meanings of the word "sedition" are not among its original meanings.
