Online video games have become a significant arena for wealth creation and circulation within the digital economy. The emergence of digital assets, novel revenue models and complex in-game payment mechanisms has, in turn, facilitated new forms of financial misconduct. This article adopts an analytical and interdisciplinary approach to examine the challenges of Islamic economic jurisprudence in addressing financial crimes arising from online games. It argues that a major source of jurisprudential inefficiency lies in the improper conceptualization of the subject matter and the disconnection between Islamic economic jurisprudence and criminal jurisprudence. Using a descriptive-analytical method and drawing upon authoritative sources of Imami jurisprudence, the study identifies and analyzes five core challenges: the ambiguity of “property” and “property value” in digital assets, the legitimacy of revenues generated by online games, the overlap with gambling, uncertainty (Gharar) and unlawful consumption of wealth, the inadequacy of existing frameworks for criminalization and the jurisprudential-economic responsibility of platforms and game developers. The findings indicate that focusing solely on users’ conduct fails to capture the structural nature of digital financial crimes, necessitating a shift toward analyzing crime-producing economic architectures. The article further establishes a methodological linkage between Islamic economic jurisprudence and criminal jurisprudence by proposing a redefinition of the object of crime-from individual acts to economic structures-revisiting the foundations of criminal liability based on doctrines such as causation (Tasbīb) and no-harm (Lā Zarar) and advocating for a jurisprudence-based criminal policy. The study concludes that such integration enables Islamic jurisprudence to function both as an effective regulator of the digital economy and as a framework for fair and preventive responses to financial crimes in online gaming environments.
