This paper aims to explore the values of justice in the Islamic inheritance system in realizing the sustainability of life. The method used in this research is normative juridical with descriptive analysis. The study results show that justice is one of the essences of Islamic teachings. Justice in the inheritance law system is closely related to the rights and obligations of the heirs and heirs and society, which can be viewed from theological, economic, and social perspectives. The basis for implementing inheritance law in the perspective of justice is to ensure order and justice for transferring assets from the deceased to their heirs. Justice is meant to treat the same or not to distinguish one person from another or the existence of equal rights. This shows that Islamic inheritance law provides social security for underprivileged families. If the Islamic inheritance system is practised properly and correctly, it will create unity and sustainability in collective life.
