Why a credit price may exceed a cash price, where interest begins, and how benchmarks should be understood Read the bilingual lesson for Deferred Pricing and Benchmarks in Cost-Plus Sale (مرابحة) and test your understanding with a focused quiz.
Lesson
1. The Central Question
In cost-plus financing (مرابحة), the financier often buys a commodity for cash and sells it to the client for a higher deferred price. If the higher price reflects extra time, how is that different from interest? The answer begins by distinguishing money from commodities.
This rule is especially important in financing because cost-plus sale (مرابحة) is valid only when the financing remains a real sale. The sequence of ownership, possession, risk and final sale must therefore be visible in the transaction.
2. Money and Commodities Do Not Function the Same Way
A commodity has intrinsic utility and may differ in quality, condition, location and usefulness. Money of the same denomination functions primarily as a medium of exchange; one Rs. 1,000 note does not become legally more valuable merely because it is newer than another Rs. 1,000 note.
This rule is especially important in financing because cost-plus sale (مرابحة) is valid only when the financing remains a real sale. The sequence of ownership, possession, risk and final sale must therefore be visible in the transaction.
3. Same Currency Must Be Exchanged at Par
When the same currency is exchanged for itself, an excess on one side has no separate commodity or service behind it. In deferred money-for-money exchange, an added amount is therefore claimed merely for time. That is the type of excess that falls into interest/usury (ربا).
This rule is especially important in financing because cost-plus sale (مرابحة) is valid only when the financing remains a real sale. The sequence of ownership, possession, risk and final sale must therefore be visible in the transaction.
4. A Commodity Price May Reflect Many Factors
A commodity seller may charge more because of location, reliability, service, availability, customer preference—and also deferred payment. Once buyer and seller freely agree on one final price, the whole price is attributed to the commodity. Time may influence pricing before sale but does not remain a separate debt charge afterward.
The important point is certainty at the time of contract. Different options may be discussed beforehand, but once the sale is concluded one definite price must govern the transaction.
5. Cash Price and Credit Price May Differ
During negotiation the seller may quote Rs. 100 cash or Rs. 110 on six months' credit. This is valid only if the buyer chooses one option when the sale is concluded. Once Rs. 110 for six months is selected, that becomes the single sale price.
The important point is certainty at the time of contract. Different options may be discussed beforehand, but once the sale is concluded one definite price must govern the transaction.
6. Late Payment Cannot Create a New Increase
A higher deferred price is fixed once as part of the sale. If the buyer later misses the due date, the seller cannot add another percentage for extra time. That later addition would be an increase on an existing debt rather than part of the commodity price.
This rule is especially important in financing because cost-plus sale (مرابحة) is valid only when the financing remains a real sale. The sequence of ownership, possession, risk and final sale must therefore be visible in the transaction.
7. Using an Interest Rate as a Benchmark
Some Islamic financial institutions have historically priced cost-plus sale (مرابحة) by reference to prevailing interest-rate benchmarks such as LIBOR. The key distinction is between the legal nature of the transaction and the external indicator used to choose a price.
A benchmark may help choose a market price, but it cannot replace the requirements of a valid sale. Ownership, possession, risk and a fixed contract price must still exist independently.
8. Benchmarking Does Not Replace the Sale Conditions
If the transaction is a genuine sale satisfying ownership, possession, risk and price rules, merely using an interest-rate figure as a pricing reference does not by itself convert it into an interest-bearing loan. But the practice is still undesirable because it creates resemblance to conventional finance and dependence on its pricing system.
Commercial flexibility remains possible, but uncertainty should not be built into the basic existence of the sale. The parties should know what has been sold, for what price and under which valid conditions.
9. Why an Islamic Benchmark Is Preferable
A better long-term direction is to develop benchmarks from Shari‘ah-compliant asset-backed market activity. One proposed route is an interbank pool invested in partnership (مشاركة), leasing (إجارة) and other tangible-asset structures. If the pool is substantially represented by tradable tangible assets, periodic net asset value can provide market information for liquidity and pricing.
10. The Boundary to Remember
Time may influence the price of a commodity before a sale is finalized. But once the price is fixed, time cannot keep producing additional money on the resulting debt. This explains why a higher credit price can be valid while a late-payment increase on the same debt is not.
This rule is especially important in financing because cost-plus sale (مرابحة) is valid only when the financing remains a real sale. The sequence of ownership, possession, risk and final sale must therefore be visible in the transaction.
