Cross-Standard Case Studies: Integration and Real-World Application

Case Study 1: Multi-Standard Scenario — Auto-Finance with Cooling-Off and Defect

Scenario: An Islamic bank structures a car Murabahah with a 10-day cooling-off option. The customer pays a $5,000 Hamish Jiddiyyah (security deposit) and receives the car.

• Day 3: The customer exercises the cooling-off option and revokes the contract, returning the car in good condition.
• Day 8: The bank tries to resell the car but discovers a hidden engine defect (Khiyar al-Ayb).

Questions:

• Does the customer's revocation affect the bank's rights against the supplier who sold the car to the bank?
• Does the cooling-off option override the defect option?

Analysis: These standards operate independently:

• The customer invoked the cooling-off option within the 10-day window. The contract between bank and customer is terminated, and the $5,000 Hamish Jiddiyyah is returned to the customer.
• The defect option applies to the bank's contract with the supplier. The bank now has an option to revoke against the supplier, claiming the hidden defect made the car unfit for resale.
• The bank receives back the car from the customer on Day 3, then discovers the defect on Day 8. The bank can pursue defect claims against the supplier independently of the customer transaction.

Case Study 2: Convergence of Price Gouging and Cooling-Off

Scenario: A bank sells real estate to a customer with a 30-day cooling-off option. Price: $500,000. On Day 15, a comparable property two blocks away sells for $350,000, suggesting the bank overcharged by about $150,000 (Khiyar al-Ghabn).

Questions:

• Which standard applies: price gouging or cooling-off?
• Can the customer invoke both?

Analysis: Both can apply, but they serve different purposes:

• Cooling-off: The customer may revoke for any reason, or no reason, within 30 days simply to reconsider. No proof of price gouging is needed.
• Price gouging (Khiyar al-Ghabn): The customer must prove the price exceeded certified valuators' highest estimate and that the customer was unaware at inception. This is a claims-based option that requires proof.

In practice, the customer would invoke cooling-off because it is simpler: just revoke within 30 days. Price gouging would apply only if the customer missed the 30-day window but can prove gouging within the customary period for that claim.

Case Study 3: Waqf, Zakah, and Modernization

Scenario: A wealthy family establishes a $10M Waqf for a hospital. The Waqf is invested in a diversified Shari'ah-compliant portfolio of shares, sukuk, and real estate generating $400,000 per year. The hospital operates at a loss some years. The family argues they should be allowed to reduce Waqf payouts to preserve capital.

Questions:

• Is the Waqif or his successors allowed to modify the Waqf to preserve capital?
• Does Zakah apply to the Waqf assets?

Analysis:

• Waqf irrevocability: The Waqf is irrevocable. The original declaration fixed the terms. However, the Mutawalli has discretion to manage the asset prudently, invest conservatively if needed, and maintain the asset for perpetuity. The Waqif's successors cannot retroactively change the Waqf terms, but prudent management can be adopted through the Mutawalli.
• Zakah on Waqf assets: Waqf assets themselves are exempt from Zakah because they are dedicated to charitable purposes. If the Waqf generates income exceeding its charitable needs, most scholars exempt that income entirely; a minority view may treat excess income as subject to Zakah if the Waqf fails its charitable purpose.

Case Study 4: Contingent Incidents in Salam and Istisna'a

Scenario: An Islamic bank enters a Salam contract to purchase 500 tons of wheat from a farmer, paying $250,000 upfront for delivery in 6 months. Mid-season, a severe drought destroys 80% of the farmer's harvest. The farmer can deliver only 100 tons from his own crop.

Questions:

• Under the contingent-incident rules, is the farmer relieved of his obligation?
• What remedy does the bank have?

Analysis:

• Risk allocation in Salam: The seller bears production and sourcing risk because Salam is an obligation to deliver generic goods, not the seller's particular harvest. The buyer paid upfront and is entitled to the contracted quantity.
• Farmer's remedy path: The farmer must source wheat from elsewhere and deliver 500 tons if equivalent wheat is reasonably available. If objective impossibility prevents delivery, he must refund the bank for the undelivered quantity, such as $200,000 for the missing 400 tons. Court adjustment is relevant only where hardship or impossibility meets the required threshold.
• Bank's remedy: If the farmer cannot deliver and refuses to refund the undelivered portion, the bank may pursue a Salam default claim and seek court relief or damages.
