Wakalah

An agency contract where one party (the principal) appoints another (the agent, or wakil) to conduct transactions or manage investments on their behalf. The agent earns a fee (ujrah) or, in some structures, a share of profit for their services.

Wakalah is widely used in Islamic finance for investment management (Wakalah bil-Istithmar), where investors appoint a fund manager as their agent. It is also one of the two main operational models for Takaful — in the Wakalah model, the insurance operator manages the takaful fund for a fixed agency fee rather than a profit share.

Wakalah is agency — authorizing someone to act on your behalf — and it is the invisible connective tissue of Islamic finance, governed by AAOIFI's agency standard. The contract is simple (principal, agent, defined mandate, optional fee) but its applications are everywhere: an Islamic bank buys your Murabaha home as your purchasing agent before the credit sale; fund managers run halal portfolios as wakil for a disclosed fee (wakalah bi al-istithmar — investment agency); the dominant Takaful model pays the operator a wakalah fee for administering the participants' pool; letters of credit, bill collection, and payment processing all run on agency; and in Islamic marriage practice, a bride may appoint a wakil to contract the nikah on her behalf.

The rules that matter: the agent owes the principal fidelity to the mandate and is a trustee over entrusted funds (liable only for negligence or breach); the fee must be defined (flat or percentage of assets — both valid because they price service, not credit); and the agent may not profit secretly from the mandate. Wakalah's boundary with Mudarabah is a live design question in products: an agent earns their fee regardless of outcome, a mudarib earns only from profit — so 'fee plus performance incentive' hybrids need careful structuring, which AAOIFI permits within limits.

Consumer relevance: when your halal provider is your wakil, you bear investment outcomes and they owe you diligence — read the mandate you signed.
