Case Study 1: Murabahah Ecosystem
Bank finances TechCo equipment purchase through four layers:
- Agency (Wakala): Logistics firm sources equipment on the bank's behalf.
- Guarantee (Kafalah): Personal guarantor plus customer guarantee.
- Mortgage (Rahn): Equipment is mortgaged.
- Hiring (Ijarah): Account management is outsourced.
Each element is independently compliant and serves a distinct function.
Case Study 2: Investment Fund Layers
The fund appoints three role layers:
- Investment Agent: Asset manager, fixed fee plus performance incentive, fiduciary, binding contract.
- Sub-Agent Ju'alah: Debt collector, result-based, non-binding until work commences.
- Legal Counsel Agency: Fixed retainer agency.
Risk and liability differ by contract type.
Case Study 3: Trade Finance L/C
Exporter applies for an L/C from the bank. The structure has four components:
- Documentary Credit: Bank issues an undertaking to pay upon document conformity.
- Guarantee embedded in L/C: Bank's undertaking functions as guarantee support.
- Agency in L/C: Bank examines documents.
- Service Fee: A fee is permissible for the L/C issuance service.
Case Study 4: Agency + Guarantee Conflict
Problem: Bank appoints the same employee as both Investment Agent AND Guarantor for fund performance — PROHIBITED per the Guarantees standard (conflicting roles). Solution: Separate roles — agent as fiduciary (fees, no guarantee); any guarantee must come from a genuinely independent guarantor and must not cover profit.
Liability Framework Across Contracts
| Contract Type | Actor | Liable For | Not Liable For |
|---|---|---|---|
| Agency (Wakala) | Agent | Negligence, breach of instructions | Market changes, force majeure |
| Investment Agency | Agent | Misconduct, negligence, breach | Market loss, profit target shortfall |
| Ju'alah | Worker | Negligence during work | Failure to achieve result (unless misconduct) |
| Hiring (Ijarah) | Employee | Negligence, breach of instruction | Force majeure, normal wear |
| Guarantee (Kafalah) | Guarantor | Debt payment upon default | Claims beyond original debt amount |
| Mortgage (Rahn) | Mortgagee | Duty to maintain, not use asset | Force majeure damage |
| Investment Manager Liability | Manager | Willful misconduct, negligence | Market losses, profit targets |
Unifying Principle
All Domain D contracts embody four Maqasid:
- Enable commerce through delegation and intermediation.
- Protect trust via liability rules for trustees and fiduciaries.
- Fair risk allocation so each party bears appropriate risk.
- Transparency through disclosure and clear terms.
This allows layering contracts without losing Shari'ah integrity.
