Halal certification plays an important role in ensuring the welfare of Muslims, both physically and spiritually. This is closely related to the principle of hifzh nafs in maqashid sharia which aims to protect human life and welfare. Although the importance of halal certification in the global market is increasing, there is still a lack of research that examines the direct relationship between halal certification and the protection of consumer health, safety, and spiritual peace. This problem is especially evident in studies that focus more on the economic or technical aspects of halal certification, without fully exploring its impact on consumer welfare from a holistic Islamic perspective. This study aims to fill this gap by analyzing the relationship between halal certification and the principle of hifzh nafs through a literature review approach. The research method used is descriptive qualitative, by collecting data from literature studies that include journals, books, and legal regulations related to halal certification and maqashid sharia. The results of the study indicate that halal certification functions as a guarantee of the physical, mental, and spiritual safety of consumers by ensuring that the products consumed do not contain ingredients that harm the body or soul. Halal certification also helps avoid potential risks that can affect physical and mental health, while providing peace of mind to consumers. Therefore, halal certification not only guarantees the halalness of products from a religious perspective, but also supports the protection of human life and welfare in accordance with the principles of maqashid sharia.
