Buy-Now-Pay-Later (BNPL) services, led by giants like Klarna and Clearpay, have fundamentally changed how the UK shops. By splitting purchases into three or four interest-free installments, they provide a flexible alternative to credit cards. However, for a Muslim shopper, the question isn't just "is there interest?" but "what happens if I sign a contract that could charge me a fee?"
Scholarly consensus overview
Contemporary scholars and Shariah advisory boards generally divide the BNPL debate into two categories: the technical transaction (the loan) and the contractual agreement (the terms of use).
The BNPL Mechanism: Qard vs. Commercial Debt
To understand the ruling, we must first define the contract. When you buy a £60 pair of shoes on Klarna, Klarna pays the shop £60 immediately (usually minus a commission). You then owe Klarna £60 to be paid over time.
In Shariah, this is a Qard (Loan). The fundamental rule of Qard is that any benefit derived by the lender from the borrower is Riba.
The Merchant Fee
Klarna makes money by charging the retailer a fee. Scholars generally allow this as it is a fee for a separate service (payment processing/marketing) paid by the seller, not a cost paid by the borrower.
Interest-Free installments
As long as the total paid by the consumer equals the cash price of the goods, there is no inherent Riba in the exchange itself. This is seen as a virtuous "Good Loan" (Qard al-Hasan).
The Late Fee Dilemma: Conditional Riba
The "Red Line" for most scholars is the Late Payment Fee. In Islamic law, a penalty for failing to repay a debt on time is considered Riba al-Jahiliyyah (the Riba of the pre-Islamic era).
Even if Klarna does not call it "interest," a flat fee of £5 charged because a payment was late functions mathematically and legally as a penalty on debt. This leads to several schools of thought:

UK Context: The Reintroduction of Fees
The UK market is particularly relevant. For several years, Klarna UK operated without late fees for its "Pay in 3" and "Pay in 30" products. During this period, several UK-based scholars viewed the service with more leniency.
Market Update
What changed in 2023?
In March 2023, Klarna UK reintroduced late fees of up to £5 per missed payment (capped at 25% of the total order value). This move was seen as a way to manage higher borrowing costs but significantly complicates the Islamic ethical standing of the service.
Contractual Validity: Signing the Agreement
A common question is: "If I never pay late, does it matter if the fee is in the contract?"
- The Majority View: Entering into a contract that contains a prohibited clause (Riba) is impermissible in itself. The Prophet (pbuh) cursed the one who consumes Riba, the one who pays it, the one who records it, and the two witnesses to it. They are all considered equal in sin. By signing the Klarna contract, you are "recording" and "witnessing" a Riba agreement.
- The Minority/Leniency View: Some contemporary councils argue that if there is a 100% certainty that the fee will not be triggered (e.g., through auto-debit and having ample funds), the clause remains "dormant" and the primary transaction (the interest-free purchase) remains valid. This is often applied only in cases of "Need" (Haja) rather than luxury.

The Red Line
Where do scholars draw the line?
While opinions vary, the consensus hardens in the following three scenarios:
- 1Interest-Bearing Financing:
Klarna's longer-term financing options (over 6-36 months) often carry explicit APR interest rates. These are universally considered Haram by all schools of thought.
- 2Intentional Late Payment:
Accepting a late fee as a "convenience cost" for not having money now is actively paying Riba. This is a clear red line.
- 3Dependency & Israf:
Using BNPL to fund a lifestyle of luxury and wastefulness (Israf) is spiritually discouraged, even if the financial mechanics were perfectly compliant.
Ethical Considerations: Debt and Israf
Beyond the technical legality, there is the Maqasid (Higher Intents) of Shariah. Islam encourages a lifestyle of moderation and cautions against the "burden of debt" (Hammu al-Dayn).
The Prophet (pbuh) used to seek refuge from debt, saying: "When a man gets into debt, he speaks and lies, and makes a promise and breaks it." BNPL services are designed by behavioral psychologists to lower the "pain of paying," often leading users to spend 20-30% more than they would with cash.
Ethical Discipline Planner
1. Affordability: Could you pay for this in full today?
2. Necessity: Is this an essential item or a luxury?
3. Risk: Is there any risk you might miss a payment?
Summary & Practical Guidance
Can you use Klarna if you pay on time? The answer depends on your level of precaution:
The Conservative Stance
Avoid all BNPL services that include a late fee clause, as signing the contract is seen as consenting to a Riba agreement.
The Balanced Approach
If using the service for an essential need, ensure 100% auto-payment and zero risk of penalty. Treat it as a "Qard" that must be guarded strictly.
