Crime prevention is one of the central objectives of criminal policy in Islamic legal systems, grounded in the principles of justice, responsibility, and the moral reform of both the individual and society. Within this framework, the family, as the most fundamental social institution emphasized by Islamic teachings, plays an irreplaceable role in raising future generations, transmitting divine and social values, and preventing deviant behavior. Using a descriptive-analytical method, this study examines the position of the family in crime prevention and seeks to clarify its role in processes of socialization rooted in Islamic teachings, internal moral control, and the strengthening of religious conscience. The findings indicate that the family can effectively contribute to reducing delinquency across the three levels of prevention: primary (before crime occurs), secondary (at-risk individuals), and tertiary (after offending), through Islamic educational methods, emotional cohesion, and moral supervision. Elements such as parenting style, parental monitoring, the family’s cultural structure, and faith-based bonds play decisive roles in preventive effectiveness. However, challenges including the weakening of the family’s educational role, the penetration of Western lifestyle models, and neglect of religious upbringing constitute significant barriers to utilizing the full preventive capacity of the family within an Islamic framework. Accordingly, strengthening the family based on Qur’anic principles and Prophetic tradition, enhancing parents’ educational literacy, and reconstructing children’s religious identity are proposed as key strategies for effective crime prevention.
