KembaraXtra-Islamic Finance – Istishab (Presumption of Permissibility)
Introduction
In Islamic jurisprudence, one of the fundamental guiding principles is Istishab, commonly referred to as the “presumption of permissibility.” This doctrine establishes that the default ruling for all matters is permissibility unless there is explicit evidence proving otherwise. In other words, everything is deemed lawful and permissible until a clear prohibition is found in the Qur’an, Sunnah, or other recognized sources of Islamic law.
This maxim provides flexibility and ensures that Islamic law is not unnecessarily restrictive. It acknowledges that human life constantly evolves and that new situations, contracts, and practices will continue to emerge over time. Rather than viewing every new matter with suspicion, Istishab encourages Muslims to assume permissibility, except when it can be decisively shown that an act or transaction contradicts Shariah principles.
In the realm of Islamic commercial law, Istishab plays a particularly important role. By declaring from the outset that contracts, agreements, and terms are valid unless prohibited, it fosters innovation and development in finance, trade, and partnerships. For example, the acceptance of fair value accounting as a modern valuation tool alongside traditional book value and market value is grounded on the presumption of permissibility, as no prohibition exists against it.
This principle also parallels the concept of equity in common law traditions. While common law was historically rigid and highly technical, equity was introduced to promote fairness, justice, and conscience. A famous case, Walsh v. Lonsdale, highlighted how equity could prevail over rigid law in order to prevent injustice. Similarly, in Islamic law, principles like Istihsan (juridical preference) and Istishab ensure that justice is served, even in complex or unforeseen circumstances. For instance, in a Muzaraah (agricultural partnership) contract, if the cultivator dies before the harvest, strict rules would terminate the contract immediately. However, Istihsan and Istishab are applied to presume the continuation of the partnership until the crop is harvested, ensuring the family of the deceased cultivator receives their fair share.
Thus, Istishab not only preserves fairness and justice but also allows Islamic law to remain dynamic, relevant, and adaptable to the changing needs of society.
