Is Buy Now, Pay Later Haram in Islam?

Buy now, pay later buttons are on almost every checkout page now, and they get pushed hardest in the weeks around Black Friday and the holidays. Splitting a $200 coat into four payments of $50 with "no interest" sounds harmless, but a lot of Muslims pause before tapping it. Is it a loan? Is there riba hiding in the small print?

The honest answer depends on which plan you pick and what the contract says if you pay late. Here is what the fatwas that address these products actually say, where scholars agree, and where they split.

Is buy now, pay later haram in Islam?

Interest-free buy now, pay later is not haram in itself, but interest-bearing plans are, and scholars disagree about the late-fee clause in many interest-free plans. Paying for something in installments at the same total price is a permitted form of deferred payment. The problem starts when the amount you owe can grow, either through interest or through a penalty for paying late.

The Qur'an draws the line clearly: "Allāh has permitted trade and has forbidden interest" (Qur'an 2:275). The Prophet ﷺ "cursed the accepter of interest and its payer, and one who records it, and the two witnesses, and he said: They are all equal" (Sahih Muslim 1598). As the buyer, you would be the payer, so the question is whether a given plan ever makes you pay more than you borrowed.

Why is an interest-free installment plan allowed?

Because Islam allows buying now and paying later, as long as no increase is attached to the delay. The Prophet ﷺ himself "purchased food grains from a Jew on credit and mortgaged his iron armor to him" (Sahih al-Bukhari 2068), and the Qur'an's longest verse begins: "O you who have believed, when you contract a debt for a specified term, write it down" (Qur'an 2:282).

IslamWeb (fatwa 86960, 2004) applies this to installment sales: if a sale is agreed on installments with a fixed deadline, "without a condition of an increase (interest) when there is a delay in repayments, this contract is permissible." It adds that if there is interest in case of delay, the contract "is Haram and void."

On Klarna specifically, FatwaCentre, overseen by Mufti Abdur-Rahman Mangera, answered that Klarna has "some interest free products as well as products based on interest." Because Klarna earns its money by charging the merchant a fee, the answer concludes "it would be permissible to avail of their interest free products. As for products based on interest, they would not be permissible."

Are Klarna, Afterpay and Affirm interest-free?

Their Pay in 4 plans are interest-free, but all three also sell longer plans that can charge interest, and two of them charge late fees on Pay in 4. Here is what each company's own US terms and help pages say, checked in November 2026:

Klarna's Pay in 4 agreement also describes itself plainly as a loan: "we will make the loan to you by paying the Merchant." That is why the late-fee question matters so much. A penalty added to a loan is the classic case scholars discuss under riba.

Is it haram to agree to late fees if you plan to pay on time?

This is where scholars genuinely disagree: many say signing a contract with a late-payment penalty is not allowed even if you never pay it, while others allow it if you are certain you will pay on time.

The stricter view. IslamQA (answer 96613, 2007) says it is not permissible to use credit that stipulates interest "even if a person intends to pay it off on time, because it is not permissible to approve of riba or enter a contract that includes it," and because a person "may fall into riba as the result of delaying payments due to forgetting, travelling and so on." It quotes Shaykh Ibn Uthaymeen: such a commitment is invalid "even if a person believes or thinks it most likely that he will pay it off in full," because "circumstances may change." IslamWeb holds the same position on credit cards (fatwa 130300, 2009) and even on a gym membership with a late-payment penalty (fatwa 376621, 2018): "One is not permitted to enter into a contract that includes such a condition even if he intends to avoid the delay."

These fatwas rest on collective rulings. The International Islamic Fiqh Academy's 1990 resolution on installment sales, quoted in IslamWeb fatwa 270868 (2014), says a buyer who pays late "should not be forced to make any extra payment, whether according to a prior agreement or not, because forcing him to do so renders the transaction riba." Its 2000 statement on credit cards, quoted in IslamQA 97530, says credit may not be issued with interest stipulated "even if the card applicant is determined to pay within the free period."

There is one softening inside the strict camp. IslamQA (answer 104244, 2010) says agreeing to a late-payment penalty is not allowed "unless one is forced to deal with it, in which case there is nothing wrong with that, so long as he knows that he is able to pay the amount during the grace period."

The more lenient view. FatwaCentre, in an answer approved by Mufti Abdur-Rahman Mangera and Mufti Zubair Patel, starts from the same principle, saying late payment fees "fall within the prohibition of interest (riba)." But it notes that so many modern contracts include late-payment terms that avoiding them all "would be near impossible." Under the principle of widespread hardship ('umum al-balwa), it says "contemporary scholars such as Mufti Taqi have permitted entering into a contract which stipulate late payment fees, provided that one is certain that they will make all payments on time." It concludes such a contract is permissible "provided the contract does not violate any other shar'i principle and the individual makes all payments on time."

Both sides agree on two things: actually paying a late fee to the lender is riba, and paying debts on time is a duty. The Prophet ﷺ said, "Procrastination (delay) in paying debts by a wealthy man is injustice" (Sahih al-Bukhari 2287).
