Comprehensive quality management is one of the new ideas on service delivery quality in the private sector. It has been considered a role model in the public sector and aims to improve services' quality and attract the owners' satisfaction. However, given the difference, such as service delivery in the public and private sectors, the private sector's principles are not effective in the public sector. According to the theorists, the relevant rules and regulations should be proportional to the public sector. Considering the lack of a comprehensive source for extraction of these principles, one of the essential resources for extraction that is proportional to the Islamic system is Nahjal al-Balaghah. Although the theory mentioned above does not exist in Nahjal al-Balaghah, many principles are available to improve public service delivery quality. These principles are grouped into three sections: macro principles, qualitative principles of staff employment, and qualitative principles of employee performance. In this article, the authors have used descriptive and library approaches. In addition to explaining the comprehensive quality management, they have extracted proportional rules and regulations from Nahjal al-Balaghah and compared them with the country's general employment law to find the rules for improving its services quality.
