Can a Wakalah contract be revoked?

In-Depth Analysis

One of the defining characteristics of the Wakalah contract in classical Shariah jurisprudence is its revocable (Ja'iz) nature. Either party — the Muwakkil or the Wakeel — has the right to terminate the agency unilaterally at any time, provided such termination does not cause undue harm to the other party or to third parties who have relied on the agency relationship. This principle is grounded in the understanding that agency is a voluntary delegation of authority, and neither party should be compelled to continue in a relationship that no longer serves their interests. However, Shariah scholars have identified several important exceptions to this general rule of revocability. First, if the rights of third parties have become attached to the agency — for example, if the Wakeel has entered into binding commitments on behalf of the Muwakkil with third parties — the agency cannot be revoked until those commitments are fulfilled. Second, if the Wakalah is coupled with an interest (Wakalah Al-Muqayyad bi Haq) — for example, where the Wakeel is authorized to sell goods in which the agent has a financial stake — the agency cannot be revoked unilaterally by the principal. Third, if the parties have explicitly agreed to make the Wakalah irrevocable for a specified period, some scholars (particularly from the Hanbali school) accept this as binding. In modern Islamic financial documentation, the question of revocability has become a critical commercial and legal issue. Many Wakalah-based investment products and Sukuk structures require the agency to remain in place for the duration of the investment or the Sukuk tenor. If the Wakalah could be terminated at any time by either party, the entire product structure would become unstable. To address this, Islamic financial institutions typically include contractual provisions that restrict the right of termination to specified events of default or material breach, effectively creating an irrevocable Wakalah for the term of the product. The IIFM and AAOIFI have both addressed this issue in their documentation standards. The AAOIFI Shariah Standard No. 23 acknowledges that where both parties agree to restrict the right of termination, and where such restriction serves a legitimate commercial purpose, the arrangement is Shariah-compliant. The Tahawwut Master Agreement (developed jointly by ISDA and IIFM) also includes provisions for the continuity of agency arrangements in the context of Islamic hedging transactions. The author notes that the tension between classical revocability and modern commercial necessity is one of the most actively debated areas in contemporary Islamic finance jurisprudence.
