In plain words

Two friends each give a third friend 10,000 to open a coffee shop. The first says: pay me back 10,800 next year, whether the shop does well or not. The second says: I am your partner, and we split whatever profit the shop makes. Both expect a return. Only the first is guaranteed one, without owning anything or sharing any risk. In Islamic law, that guaranteed extra 800 is riba.

Riba is usually translated as interest or usury. Precisely, it is any increase on a loan of money agreed in advance, and any increase on a debt in return for more time to pay. The rate does not matter. Money is treated as a measure of value, not something that earns just by being lent.

A financier may profit by buying and selling real goods, renting out assets it owns, or sharing a business’s actual results. That is why the Islamic contracts exist: murabaha, tawarruq, ijara and musharaka. This page also covers the two other core prohibitions, gharar and maysir.

How it works

How a financier earns without riba

The same customer need, financed so the return is tied to an asset or a real risk.

  1. 1

    Start from the real need

    A car, a home, stock for a shop. The question is what is being bought, not only how much cash is needed.

  2. 2

    Pick a contract that fits

    A sale, a lease, a partnership or a fee for a service. Each creates a different kind of return.

  3. 3

    The financier owns or shares the risk

    It buys the asset before selling it, keeps owning what it rents, or puts capital at risk. This step separates profit from riba.

  4. 4

    The debt never grows

    An agreed sale price stays fixed even if the customer pays late. Any late charge typically goes to charity.

Interest loan, murabaha sale and partnership compared Three rows, each starting with 10,000. A loan gives cash to a borrower who bears all risk, and the lender gets 10,800, more if late. A murabaha bank buys a car, owns it, then sells it for a fixed 10,800. A partnership puts cash into a shop both own and shares real profit or loss. MONEY GOES TO OWNERSHIP AND RISK FINANCIER GETS LOAN Interest Conventional TRADE Sale Murabaha EQUITY Partnership Musharaka Cash to borrower Spend it on anything Bank buys a car Pays dealer 10,000 Cash into a shop Partner runs it Borrower owns it Bears every loss Bank owns first Then sells at 10,800 Both share it Capital bears losses Gets 10,800 Fixed; grows if late Gets 10,800 Fixed; never grows Share of profit No fixed return Only the loan earns a promised increase on money itself Sale profit comes from owning an asset; partner profit only from real profit.

  1. The lender hands over cash. The bank in a sale buys a real car. The partner puts money into a shop.
  2. Ownership decides who carries risk. The borrower owns what the cash buys; the bank owns the car until it sells it; the partners own the shop together.
  3. Lender and seller both receive 10,800, but only the lender’s claim can grow. The partner shares real profit, or loss.
  4. The numbers can match a loan. The ownership step and the fixed debt make the difference.
Where the financier owns something or shares the risk, Islamic law allows a profit; where it only lends money, the increase is riba.

The word and where it comes from

In Arabic the word is ربا, pronounced RI-ba, from the root r-b-w, ر ب و, meaning to increase or grow. In finance it is the increase a lender takes on top of the amount lent.

In pre-Islamic Arabia a creditor would offer a debtor a choice at maturity: pay now or owe more later. Scholars call this riba al-jahiliyya, the clearest case of the prohibition.

Where the prohibition comes from

Riba is prohibited in the Quran, in the Sunna (the reported sayings and practice of the Prophet Muhammad) and by the agreement of classical scholars. The passage most often cited is verses 2:275 to 2:279. In summary: God has permitted trade and forbidden riba; believers should give up riba still owed and keep only their capital, neither wronging nor being wronged. Verses 3:130, 4:161 and 30:39 are also cited.

“Trade is permitted and riba is forbidden” is the key: a credit sale at a higher price and a loan are different in kind, even when the cash flows look alike.

A widely reported hadith in Sahih Muslim names six items: gold, silver, wheat, barley, dates and salt. In paraphrase, each must be exchanged like for like and hand to hand; when the kinds differ, the amounts may differ, but delivery must still be immediate.

The two kinds of riba

Riba al-nasi’ah (delay)Riba al-fadl (excess)
What it isPre-agreed increase on a loan, or on a debt for more timeUnequal exchange of the same ribawi item
ExampleLend 1,000, take back 1,10010 grams of gold for 11 grams
Where it bites todayLoans, deposits, overdrafts, card and late-payment interestCurrency exchange, gold products

Riba al-nasi’ah is what most people mean. In the mainstream view, interest on a personal loan, a mortgage, a savings account or an overdue card balance are all forms of it.

Riba al-fadl sounds archaic but matters for modern products. The classical schools disagree on why the six items were chosen and how far the rule extends. Most contemporary scholars and standard setters, including AAOIFI, apply the gold and silver rule to today’s currencies. 1

  • Currency exchange must be spot. Dirhams for pounds at any agreed rate is fine if both sides are delivered at the time of the deal. AAOIFI’s standard on trading in currencies sets out the rule. 1
  • Forwards are not accepted by most scholars, because the rate is fixed today and both currencies move later. Islamic treasuries hedge with a one-sided promise (wa’d) instead.
  • Remittance and FX apps should not lock a rate while the customer’s money arrives days later without a reviewed structure.
  • Gold products need real, allocated gold and immediate possession, physical or constructive.

Why profit from trade and rent is allowed

01

Ownership

You can only sell or rent what you own. The bank must buy the car before selling it.

02

Risk

An owner carries damage, loss and a fall in value. A lender carries only the borrower’s credit risk.

03

A real asset

The return is tied to goods, a service or a business, not to money alone.

Time value: allowed in a price, not in a loan

Most scholars accept that a seller may charge more for a credit sale than for cash. A car priced at 10,000 cash may be sold for 10,800 over a year,. What cannot happen is the debt growing afterwards: no extra for late payment, no compounding. This is why a profit rate can track EIBOR, SAIBOR or SOFR. The contract, not the number, decides whether it is riba.

Try it

Who carries the risk: interest loan or profit-sharing

Move the business result. The lender’s return stays flat; the partner’s follows the business.

Worked example: a financier provides AED 100,000. An 8% loan pays it AED 8,000 whatever happens. If the business makes 20% (AED 20,000), the entrepreneur keeps AED 12,000. Under a mudaraba with a 50% profit share, the financier receives AED 10,000 and the entrepreneur keeps AED 10,000. If the business loses 10% (AED 10,000), the lender still gets AED 8,000 and the entrepreneur is down AED 18,000; under the mudaraba the financier bears the AED 10,000 loss and the entrepreneur loses only the work put in, unless the loss came from negligence or breach.

The three core prohibitions and what each rules out

Riba, gharar and maysir Three columns: riba, gharar and maysir, each with what it rules out, such as loan interest, conventional insurance and betting, and what Islamic finance uses instead, such as sales, takaful and real business risk. PROHIBITION 1 Riba Increase on money PROHIBITION 2 Gharar Unclear terms or object PROHIBITION 3 Maysir Gain from pure chance RULES OUT Interest on loans Late-payment interest Deferred FX or gold swap Unequal gold for gold RULES OUT Selling what you lack Undefined price or date Conventional insurance Speculative derivatives RULES OUT Betting and lotteries Prize draws you pay into Pure speculation Zero-sum bets on prices USED INSTEAD Sales, leases, partners Spot FX, qard accounts USED INSTEAD Clear specs and prices Takaful, salam, istisna USED INSTEAD Real business risk Unpromised gifts (hiba)

Swipe sideways to see the whole diagram.

A product can avoid interest and still fail on gharar or maysir. Sharia boards test all three.

Gharar: excessive uncertainty

Gharar, غرر, means hazard. A contract has prohibited gharar when something essential is unknown: what is sold, its quantity or quality, the price, or whether and when it will be delivered. Minor, unavoidable uncertainty is tolerated.

  • Insurance became takaful. Most scholars see a conventional policy, a premium for a payout that may never come, as gharar, with elements of maysir and riba in its investments. In takaful (تكافل, mutual guarantee) participants donate to a shared fund that pays claims, run by an operator for a fee or profit share.
  • Options and many derivatives. Most standard setters do not accept trading conventional options and futures. Islamic hedging uses promises and real exchanges, documented under the ISDA and IIFM Tahawwut master agreement.
  • Permitted exceptions. Salam (paying now for goods delivered later) and istisna (ordering something to be made) are allowed because goods, price and date are precisely specified.

In fintech, gharar looks like vague fees, prices changeable at will, or tokens with unclear rights.

Maysir: gambling and speculation

Maysir, ميسر, is gain from pure chance, where one side’s win is the other’s loss and nothing productive happens in between. The Quran prohibits it, for example in verse 5:90. It excludes betting and lotteries. What matters is whether a return comes from real activity or a bet.

  • Prize-linked savings. Products like the UK’s Premium Bonds pay prizes instead of interest, which many scholars see as raising both riba and maysir. Some Islamic banks give unpromised prizes on current accounts as a gift (hiba); some scholars accept this, others do not.
  • Crypto trading. Scholars differ on whether spot trading of major cryptoassets is permissible. There is wider agreement that interest-funded margin, perpetual futures and options-style products raise concerns.
  • BNPL late fees. Interest-free instalments are not maysir. The risk is riba: a fee that grows with delay increases a debt. Some Sharia-reviewed plans charge no late fee; others charge a fixed fee covering actual costs or given to charity.

How it differs from conventional finance

Conventional bank

  • Lends money and charges interest
  • Pays guaranteed interest on deposits
  • Debt grows with time and late payment
  • Need not own any asset

Islamic bank

  • Sells, leases or invests
  • Shares profit on investment deposits
  • A sale debt is fixed and never grows
  • Must own the asset or share the risk
Conventional loanIslamic financing
OwnershipCustomer owns; bank holds a chargeBank owns first, or co-owns
Asset riskCustomer onlyBank while it owns; shared in partnerships
Financier earnsInterest for the use of moneySale profit, rent, profit share or fee
Late paymentExtra interest or penalty incomeDebt fixed; any charge usually to charity or actual costs
Early settlementInterest stops; a fee may applyPrice owed in principle; a rebate (ibra) is common, often required
Variable ratesRate resets on the balanceMurabaha price fixed; ijara rent reviewable for future periods

How each bank earns money

A conventional bank owes depositors their money plus interest, whatever happens to its loans, and earns the spread.

An Islamic bank usually treats current accounts as a qard, a loan from the customer: repayable in full, with no return. Savings and investment accounts use mudaraba or wakala: the bank invests a pool and shares actual profit at an agreed ratio, or takes an agency fee, showing an expected rate, not a promised one. On financing, it earns sale profit, rent and partnership shares. The economics can look similar; the legal relationships and risks differ.

Tawarruq is the most debated item: AAOIFI accepts it under strict conditions, while the OIC International Islamic Fiqh Academy has rejected organised tawarruq. Each structure still goes to a Sharia board.

Is modern bank interest riba?

The mainstream answer is yes. In 1985 the OIC’s International Islamic Fiqh Academy ruled that any increase on a loan, or on a debt for more time, is riba, and urged trade-based financing instead. AAOIFI, most national Sharia authorities and the Islamic banking industry rest on this view.

A minority view exists. Some modernist scholars argued the Quran targets exploitative, multiplying debt rather than moderate interest. The best-known example is a December 2002 opinion of Al-Azhar’s Islamic Research Academy, endorsed by Sheikh Muhammad Sayyid Tantawi, accepting a pre-set return on money a bank invests for the depositor. Many scholars rejected it. This page describes both views without taking a side.

Across the Islamic world and beyond

Saudi Arabia

All banks are licensed by SAMA under one banking law, with no separate Islamic licence. In practice Islamic finance dominates retail banking, and banks have Sharia committees under SAMA’s governance rules. A Riyadh wallet adding a salary advance would need a Sharia-reviewed structure.

United Arab Emirates

A dual system of conventional banks, Islamic banks and Islamic windows. The Higher Sharia Authority at the Central Bank of the UAE, approved in 2016 and set up in 2017, issues standards binding on licensed Islamic institutions. 2 A Dubai remittance app offering an Islamic account must follow them in its own structure.

Bahrain and Malaysia

Bahrain hosts AAOIFI, and its central bank requires Islamic banks to follow AAOIFI’s Sharia standards. Malaysia runs a dual system under the Islamic Financial Services Act 2013, with a Shariah Advisory Council at Bank Negara Malaysia whose rulings bind institutions and courts. 3

Pakistan, Iran and Sudan

In April 2022 Pakistan’s Federal Shariat Court declared interest-based banking un-Islamic and set the end of 2027 to eliminate riba. 4 A 2024 constitutional amendment set the target of 1 January 2028, as far as practicable; some bank appeals remain pending. Iran moved its whole system to usury-free banking under a 1983 law. Sudan ran a fully Islamic system for decades and announced a return to dual banking in 2021.

United Kingdom and the EU

Interest is legal; riba is a religious rule. UK Islamic banks are authorised like any other bank, and alternative finance tax rules remove double stamp duty on home purchase plans. Continental Europe has no specific framework. A Lithuanian EMI wanting an Islamic account must consider that customer money is safeguarded at banks, where it may earn interest.

Where riba hides in a fintech product

RoundingInstalments total more than the priceLast instalment absorbs the difference

Example: a Gulf wallet adds an Islamic savings pot

Noura leads product at a fictional UAE wallet whose customers want Sharia-compliant savings.

  1. First draft. Pay 3% a year, funded by the interest the partner bank pays on pooled funds. The Sharia adviser stops it: a promised return on money is riba.
  2. Redesign. The pot becomes a wakala investment with a licensed Islamic bank. The app shows an expected profit rate, labelled not guaranteed, and pays actual profit monthly.
  3. Hidden problems. Round-ups were swept into an interest account, and users could lock an FX rate for 48 hours. Round-ups now go to the pot; the lock becomes an instant exchange once funds arrive.
  4. Evidence. The back office records each wakala appointment, profit calculation and Sharia approval.

Common misconceptions

“Islamic finance means no return on money.”

Profit, rent and profit shares are allowed. What is prohibited is a guaranteed increase on money lent, with no ownership or shared risk behind it.

“Only high or compound interest is riba.”

In the mainstream view any pre-agreed increase on a loan is riba, however small.

“Rename interest as profit and the product is compliant.”

Labels change nothing. Compliance depends on contracts and operations, approved by the Sharia board, including the ownership step and a debt that never grows.

FAQ

What is riba in simple terms?

Riba is a fixed, pre-agreed increase on a loan of money, or on a debt because it is paid later. If you lend 1,000 and the borrower must repay 1,080 whatever happens, the extra 80 is riba under Islamic law.

Is all bank interest riba?

Most contemporary scholars and Islamic standard setters, including the OIC's International Islamic Fiqh Academy, treat interest on bank loans and deposits as riba. A minority view, most famously a 2002 opinion from Al-Azhar's Islamic Research Academy, accepted pre-set returns on bank investment deposits, but it remains a minority position.

How do Islamic banks make money without interest?

They earn a profit from selling assets at a marked-up price (murabaha), rent from leasing assets they own (ijara), a share of real profits from partnerships (musharaka and mudaraba), and fees for services. In each case the bank owns something or carries a real risk, rather than charging for the use of money alone.

Why is a murabaha profit not just interest with another name?

In a murabaha the bank buys an asset and sells it at a fixed price, so it carries the owner's risk for a while, and the debt can never grow after the sale, even if payment is late. The numbers can look similar to a loan, which is why Sharia boards check that the ownership step really happens.

What are riba al-nasi'ah and riba al-fadl?

Riba al-nasi'ah is riba of delay: any pre-agreed increase on a loan or deferred debt. Riba al-fadl is riba of excess: exchanging unequal amounts of the same ribawi item, such as gold for gold, or exchanging such items without immediate delivery.

Is currency exchange allowed in Islamic finance?

Yes, if it is done spot, with both currencies changing hands at the time of the deal, at whatever rate the parties agree. A conventional forward, where the rate is fixed today but both currencies move later, is not accepted by most scholars, so Islamic products hedge with promises instead.

What are gharar and maysir?

Gharar is excessive uncertainty about what is sold, its price or its delivery, and it is why conventional insurance is replaced by takaful. Maysir is gain from pure chance, such as gambling, and it rules out bets, lotteries and most speculative derivatives.
