‌Context & Objective: The passage of time necessitates the exploration of emergent legal issues (Masa’il Mustahdatha) to find suitable solutions for modern societal challenges. In the specific context of Islamic inheritance law (Irth), it is necessary to question whether the ancient rules remain applicable in their original form or if the underlying nature of the subject has fundamentally shifted over the centuries. This article outlines the historical background of inheritance rules and investigates the potential for their modification or transformation within a contemporary legal framework. The research purpose is to demonstrate that such adjustments are conceptually possible and practically acceptable when guided by jurisprudential insight and an understanding of evolving social structures. The central research question examines whether inheritance rules should remain identical to those of the early Islamic period or if they can be adapted to meet the exigencies of time (Muqtadiyat-e Zaman).
 ‌Method & Approach: The study utilizes a doctrinal method to investigate the nature of inheritance rulings through the lens of both traditional jurisprudence and modern civil law. By examining the distinction between original (Ta’ssisi) and confirmatory (Imda’i) rulings, the authors analyze historical shifts in inheritance practices as documented in classical texts. The approach further involves assessing modern legal examples, such as the Iranian Civil Code and state regulations concerning inheritance tax and social security, to identify existing patterns of legislative intervention. Finally, the methodology includes a semantic analysis of the jurisprudential "Text" (Nass) to determine if its definitive nature inherently precludes evolutionary change.
 ‌Findings: The research findings indicate that inheritance rules are confirmatory (Ahkam Imda’i) in nature, having been adopted and modified from pre-Islamic customs to suit the needs of the early Muslim community. Because these rules were established based on the social rationality and tribal structures of that era, they are not considered strictly "divinely fixed" (Tawqifi) acts of worship that are immune to the influence of time and place. Historical evidence confirms that inheritance shares were frequently adjusted during the Prophet's time—such as the transitions between the alliance of brotherhood and kinship-based distribution—to support the economic stability of the nascent state. Furthermore, modern state practices, including the imposition of inheritance taxes and the selective distribution of pension benefits, already serve as functional modifications of traditional shares. The study also finds that the nature of a legal "Text" (Nass) does not philosophically forbid modification, as the prohibition against "interpretation in the face of text" is primarily a procedural safeguard for legislative order rather than an ontological barrier to legal evolution.
 ‌Conclusion: The paper asserts that a comprehensive review of inheritance rules is required to bridge the gap between historical religious dictates and modern social realities. Since the original rules were grounded in the specific emotional and tribal bonds of a past age, the dissolution of those structures in contemporary society justifies a jurisprudential revision. The article concludes that the modification or "tempering" of inheritance rules is not only conceptually plausible but essential for maintaining social justice and the relevance of the legal system. Such changes should be implemented by legal and religious authorities through the lens of traditional jurisprudence (Fiqh) while accounting for the changing economic roles and social positions of modern heirs. Ultimately, aligning inheritance law with the actualities of contemporary life ensures that the spirit of justice within the Sharia remains vibrant and effective.
