To achieve excellence and happiness in individual and social dimensions, humans need both rights and ethics. The existence of ethical rules alongside legal rules is essential for constructing a worthy and civilized society. Legal and ethical systems are designed as complementary to each other to organize and manage human material and spiritual life. The relationship, interaction, and correlation between ethics and law are among the most important topics in the philosophy of law. There is a logical relationship between general and specific ethical and legal rules. In this paper, the interaction and correlation between law and ethics in Islamic socio-political rules, based on the teachings of the Quran and Sunnah as two primary sources of Sharia, have been examined. The relationship between law and ethics in various socio-political matters such as family, civil affairs, criminal law, judiciary, military, and political affairs is very robust. In this research, examples of these relationships in different matters have been scrutinized and analyzed based on Quranic verses and Hadiths.
