Purpose: This study aims to analyse the Islamic legal principles governing employment as found in the book Madkhal Ila Fiqh al-Mihan and its application in Malaysia. The book Madkhal Ila Fiqh al-Mihan consists of six chapters, all of which are related to the scope of Muslim employment. In Malaysia, the application of work procedures is subject to established laws such as the Employment Act 1955, the Sabah Labour Ordinance, and the Circular on Public Service Progress. However, there are religious issues arising during work that conflict with Sharia, such as the prohibition of performing obligatory prayers by employers, the rejection of fasting-related salary claims, and gender mixing issues between male and female workers. Therefore, the initial investigation in this study is to analyze the significant elements of Islamic legal principles in employment through selected books. This study also constructs a model of Contemporary Employment Fiqh in Malaysia. Methods: The article utilizes a qualitative research design method, with data sourced from selected books, theses, journals, articles, and official portals discussing employment jurisprudence (fiqh). The analysis of this study employs content analysis methodology. The findings indicate the existence of Sharia-compliant working guidelines in the book Madkhal Ila Fiqh al-Mihan, which should be understood by every Muslim. Results and discussion: The results also show that the laws in Malaysia generally align with the principles in the book. Implications of the research: A deep understanding of this matter has a massive impact on individuals, employers, races, religions and countries in the long term, and give positive value in employees to increase productivity and quality of work. Originality/value: Therefore, it is essential for a worker to enliven Employment Fiqh to balance work with the demands of worship to Allah SWT.
