Case Study 1: The Commodity Murabahah Gone Wrong

Global Islamic Bank (GIB) offers commodity Murabahah personal finance:

  1. Client applies via mobile app for $100,000.
  2. The system purchases 50 tons of nickel on LME through Broker Alpha.
  3. The system sells nickel to the client at cost + 8% = $108,000 payable in 48 months.
  4. The client authorizes GIB to "handle logistics".
  5. GIB sells to Broker Beta for $100,000 spot.
  6. $100,000 is deposited to the client.
  7. Broker Alpha and Broker Beta are subsidiaries of the same trading house.
  8. Nickel certificates reference commingled warehouse lots.
  9. The Shari'ah board approved the product 4 years ago, but the central bank now requires proof of genuine commodity ownership transfer.
TopicFindingCompliant?
MurabahahBank purchases commodity — genuine ownership transfer needed✅ If genuine
Murabahah"Handle logistics" authorization = delegation to sell❌ Disguised agency
TawarruqCommingled warehouse lots — commodity NOT distinct
TawarruqBroker Alpha and Beta share same parent — circular
TawarruqSingle application links credit purchase and on-sale
Tawarruq"Logistics" authorization = delegation to institution
TawarruqClient plays no active role in on-sale
Fatwa Ethics4-year-old approval + new regulatory requirements = fresh fatwa needed

Case Study 2: Salam vs. Istisna'a — Choosing the Right Structure

Request A: A wheat farmer needs $200,000 to fund planting; expects 500 tons of Grade A wheat in 6 months. → Salam: wheat is fungible; farmer needs full capital upfront; strict specifications (protein ≥12%, moisture ≤14%); delivery in 6 months; NOT from a specific farm.

Request B: A tech company needs $500,000 to build a custom data center; 12-month project. → Istisna'a: custom-built item; flexible payment (20% upfront, progress payments); detailed technical specifications; manufacturer cannot exclude defect liability; bank may enter Parallel Istisna'a.

If the wheat farmer delivers only 400 tons: The buyer has three remedies:

  1. accept 400 tons and recover proportional capital for the undelivered 100 tons
  2. wait for the remaining 100 tons
  3. cancel and recover all capital

The buyer cannot claim compensation for opportunity loss.

RequestBest StructureWhyKey Controls
A: wheat farmer needs $200,000 for 500 tons of Grade A wheat in 6 monthsSalamThe wheat is fungible and the farmer needs full capital upfrontFull price paid now; wheat specified by grade, protein, moisture, quantity, delivery date, and delivery place; not tied to a specific farm
B: tech company needs $500,000 to build a custom data center over 12 monthsIstisna'aThe asset is custom-built and manufactured to technical specificationsPayment may be staged; specifications must be detailed; manufacturer cannot exclude defect liability; bank may use Parallel Istisna'a

Takeaway: Salam solves the funding need for a generic fungible commodity, while Istisna'a solves the construction need for a custom asset. The default remedy analysis follows that choice of structure: Salam short-delivery remedies protect capital without awarding opportunity-loss compensation.
