Bay' al-dayn — the SALE OF DEBT — is the contract the whole markup family finally runs into, and it is where the riba line is drawn most sharply. Every earlier entry (murabaha, bay' bithaman ajil, salam, istisna, even the contested bay' al-'inah and tawarruq) CREATES a debt by selling goods; bay' al-dayn is the onward sale of that resulting debt itself — you are no longer selling an asset, you are selling a receivable, a claim to money. Two independent sources describe it and, read together, they expose exactly why it is contested. An industry-body glossary states the classical rule flatly: 'Bay al-dayn: Sale of debt. According to a large majority of fuqaha', debt cannot be sold for money, except at its face value, but can be sold for goods and services.' A peer-reviewed trade-finance paper describes the market practice that collides with that rule: 'Bai Al-Dayn is used for the purchase and sale of debt (debt trading) at a discount or at a negotiated price.' Hold those two sentences side by side and the whole problem is visible: a debt is a claim to a fixed sum of money, so selling that claim FOR money at a discount means paying less money now to receive more money later — which is precisely the shape of riba, and precisely why the majority permit the sale only at face value (or for goods and services, where no money-for-money exchange arises). The same paper records that opinion is not uniform on WHO the debt may be sold to: 'All of the four schools of Islamic jurisprudence -- Hanafis, Shafies, Malikis and Hanbalis -- allow the sale of debt to debtor', while 'The third opinion is that the sale of debt to non-debtors is permissible' — a real spectrum, from the agreed case (selling the debt back to the one who owes it) to the disputed one (selling it to a third party).

What this source says

Bay' al-dayn — the sale of debt — is where this corpus's long march through the markup and deferred-sale contracts finally reaches the edge. Every contract before it in this collection creates a debt by selling something real: murabaha and bay' bithaman ajil sell goods at a disclosed markup payable over time; salam and istisna sell goods to be delivered later; even the contested bay' al-'inah and tawarruq generate a debt through a loop of sales. In all of them the thing being sold is an asset, and the debt is a by-product. Bay' al-dayn is the contract that takes that by-product — the receivable, the claim to a fixed future sum — and sells IT. You are no longer trading an asset for money; you are trading a claim-to-money for money. That single shift is what makes bay' al-dayn the sharpest test of the riba line in the whole family, and two independent sources, read together, show exactly why. Start with the classical rule. An industry-body glossary — the Institute of Islamic Banking and Insurance — states it in one sentence: 'Bay al-dayn: Sale of debt. According to a large majority of fuqaha', debt cannot be sold for money, except at its face value, but can be sold for goods and services.' Read that carefully, because every word is load-bearing. The majority position is not that debt can never be sold — it is that a debt sold FOR MONEY may only change hands at its face value, while a debt sold for goods and services is unproblematic. Why the asymmetry? Because a debt is, by definition, a claim to a specific quantity of money at a future date. If you sell that claim for a DIFFERENT quantity of money today — say, a claim to 100 next year sold for 90 in cash now — then money has been exchanged for money in unequal amounts across time, and that is the textbook definition of riba this entire corpus has been circling. Sell the same claim for goods, or transfer it at par, and the money-for-more-money exchange never occurs, so the objection dissolves. The face-value restriction is not an arbitrary technicality; it is the riba prohibition applied to the one commodity — a money-claim — where discounting IS interest. Now set beside that rule the way the instrument is actually used in modern markets. A peer-reviewed trade-finance paper describes the practice plainly: 'Bai Al-Dayn is used for the purchase and sale of debt (debt trading) at a discount or at a negotiated price.' There is the collision, in the space between two sentences from two different sources. The market practice is to trade debt AT A DISCOUNT; the majority of jurists permit selling debt for money ONLY at face value. A discount on a money-claim, sold for money, is the very thing the majority rule was written to forbid. This is not a tension this entry has reasoned into existence — it is the direct, verbatim collision between what the glossary says the fuqaha' hold and what the journal says the market does. It is the cleanest single illustration in this corpus of the gap between a contract's name and its cashflows: 'sale of debt' sounds like a sale, but priced at a discount for cash it behaves like a loan repaid with interest, only from the lender's side. The dispute is not only about price; it is also about the counterparty, and here the same paper records a genuine spectrum of scholarly opinion rather than a single verdict. On one point the schools agree: 'All of the four schools of Islamic jurisprudence -- Hanafis, Shafies, Malikis and Hanbalis -- allow the sale of debt to debtor.' Selling the debt back to the very person who owes it is the settled, agreed case — it is essentially the debtor settling his own obligation, and it raises none of the third-party riba worries. The contested case is the other one: 'The third opinion is that the sale of debt to non-debtors is permissible.' Selling a receivable onward to a THIRD party — someone who was never part of the original transaction — is where the schools divide and where the modern debt-trading market lives. That distinction, between selling the debt to the debtor (agreed) and to a stranger (disputed), is the fault line under every argument about whether Islamic bonds and money-market instruments built on tradable receivables are truly riba-free or merely riba relabelled. For a reader trying to keep money halal, bay' al-dayn is the entry that ties the whole corpus together, because it is the point where 'is this a sale or a loan?' stops being a matter of documentation and becomes a matter of what is actually being exchanged. The safe cases are the ones the sources agree on: transfer a debt at its face value, sell it back to the one who owes it, or exchange it for goods and services rather than for cash. The contested cases are the ones the market is built on: buying and selling other people's debts for cash at a discount, especially to third parties. Neither verified source here issues a blanket permission or a blanket prohibition, and this entry does not either — what it can say, on the strength of two independent sources, is that the majority of fuqaha' cap the money-price of a debt at its face value, that the market routinely trades debt below face value, and that the honest question a riba-free reader must ask of any 'sale of debt' product is the one this corpus keeps returning to: strip away the name, and is money simply being exchanged for more money across time? If the answer is yes, no label saves it; if the debt is genuinely transferred at par or exchanged for real goods, the majority's own rule already permits it.

According to a large majority of fuqaha', debt cannot be sold for money, except at its face value, but can be sold for goods and services') — re-fetch confirmed present character-for-character (the word fuqaha' is italicised on the page); and [2] the peer-reviewed journal paper M. A. Radzali et al., 'Examining Contracts used in Islamic Trade Financing: Issues in Bai Al-Dayn and Murabahah', International Journal of Management and Applied Research, vol. 6 no. 4, for the market practice ('Bai Al-Dayn is used for the purchase and sale of debt (debt trading) at a discount or at a negotiated price'), the four-schools agreement on selling to the debtor ('All of the four schools of Islamic jurisprudence -- Hanafis, Shafies, Malikis and Hanbalis -- allow the sale of debt to debtor'), and the disputed third-party case ('The third opinion is that the sale of debt to non-debtors is permissible') — re-fetch confirmed (A)-(C) present character-for-character. The IDENTITY (sale of debt = sale of a money-claim, distinct from selling goods), the FACE-VALUE restriction, and the four-schools-agree-on-selling-to-the-debtor point are the load-bearing facts; the riba TENSION (discount-trading vs face-value-only) is the direct collision between the two verified quotes, not a reasoned inference.

MARKET PRACTICE ('Bai Al-Dayn is used for the purchase and sale of debt (debt trading) at a discount or at a negotiated price') + FOUR-SCHOOLS AGREEMENT ('All of the four schools of Islamic jurisprudence -- Hanafis, Shafies, Malikis and Hanbalis -- allow the sale of debt to debtor') + DISPUTED THIRD-PARTY CASE ('The third opinion is that the sale of debt to non-debtors is permissible') verbatim from [2] M.

Two genuinely DIFFERENT sources cross-read — an industry-body glossary + a peer-reviewed trade-finance journal paper — the first giving the majority fiqh rule (money-price capped at face value) and the second the market practice (discount trading) that collides with it; the definition of bay' al-dayn as the SALE OF DEBT cross-confirms across both. The riba tension is the DIRECT collision between the two verified quotes (face-value-only vs at-a-discount), not a reasoned inference. The 'ties the corpus together' framing and the cross-references to the corpus's other contracts are the site's own structural map, reasoned from the verbatim material and clearly framed as such. DELIBERATELY NOT asserted because it appears in NEITHER verified source: the Malaysia-accepts / Gulf-rejects regional split, and the Securities Commission Malaysia / SAC BNM 1996 resolution (both from WebSearch summaries only; the IJMAR paper on re-fetch confirmed 'No sentences exist' affirming Malaysian acceptance or Gulf rejection).
School / basis: Comparative / contract-law (bay' al-dayn = the SALE OF DEBT: the onward sale of a receivable / money-claim, structurally distinct from every prior corpus entry because those SELL GOODS and merely create a debt, whereas this SELLS the debt itself). CLASSICAL RULE cross-read: 'Bay al-dayn: Sale of debt. According to a large majority of fuqaha', debt cannot be sold for money, except at its face value, but can be sold for goods and services' [source 1, the word fuqaha' italicised on the page]. MARKET PRACTICE (the contested collision): 'Bai Al-Dayn is used for the purchase and sale of debt (debt trading) at a discount or at a negotiated price' [source 2]. COUNTERPARTY SPECTRUM: agreed case -- 'All of the four schools of Islamic jurisprudence -- Hanafis, Shafies, Malikis and Hanbalis -- allow the sale of debt to debtor' [source 2]; disputed case -- 'The third opinion is that the sale of debt to non-debtors is permissible' [source 2]. Load-bearing for THIS site: the RIBA LINK is DIRECTLY SOURCED, not reasoned -- source 1 caps the money-price of a debt at FACE VALUE, source 2 records the market trading debt AT A DISCOUNT for cash, and a discounted money-claim sold for money is money-for-more-money across time = the riba the face-value rule exists to prevent; the safe cases (transfer at par / sell to the debtor / exchange for goods and services) are exactly the ones the two sources AGREE on. DELIBERATELY NOT asserted, per the no-fabrication rule: (a) the 'Malaysia ACCEPTS bay' al-dayn while the Middle East / Gulf REJECTS it' geographic split -- it appears in WebSearch summaries but the IJMAR paper cross-read here contains NO sentence affirming Malaysian acceptance or Gulf rejection (verified on re-fetch: 'No sentences exist'), so no regional ruling is claimed; (b) the Securities Commission Malaysia / SAC BNM 1996 resolution and any resolution number or date -- from WebSearch summaries only, NOT verified verbatim in either source, so dropped; (c) any Qur'an verse or hadith collection/number; (d) any AAOIFI/OIC/BNM-SAC resolution read directly; (e) any four-schools breakdown BEYOND the verbatim 'allow the sale of debt to debtor', any 'majority permit/prohibit' tally beyond source 1's verbatim 'large majority of fuqaha' cap at face value', any named-scholar ruling, and any market/AUM/named-bank figure.

Compiler’s note

First DEDICATED BAY' AL-DAYN (sale of debt) entry in the corpus. Grep-confirmed before writing: `ls content/articles | grep -iE "dayn|debt|receivable"` returned NOTHING for dayn/debt/receivable — no existing entry, no duplication. WHY BAY' AL-DAYN NOW: the previous run (bay' bithaman ajil, articles 62->63) named 'bay' al-dayn (sale of debt) if a two-source-verifiable pair surfaces' as an explicit next lever; this run found that pair and takes it. Bay' al-dayn is cleanly DISTINCT from every existing entry and is arguably the CAPSTONE of the markup/deferred-sale cluster: every prior contract (murabaha, BBA, salam, istisna, bay' al-'inah, tawarruq) SELLS GOODS and creates a debt as a by-product, whereas bay' al-dayn SELLS THE DEBT ITSELF — a money-claim rather than an asset — which is exactly why it is the sharpest riba test in the family. VERIFICATION: every load-bearing quote verified BY ME 2026-07-06, verbatim, across TWO genuinely different sources via a SECOND tightened re-fetch of each page — [1] the Institute of Islamic Banking and Insurance glossary (islamic-banking.com) confirmed the full 'Bay al-dayn: Sale of debt ... except at its face value, but can be sold for goods and services' sentence PRESENT character-for-character (fuqaha' italicised); [2] the IJMAR peer-reviewed paper (ijmar.org/v6n4/19-028.html) confirmed (A) the 'purchase and sale of debt (debt trading) at a discount or at a negotiated price' practice, (B) the four-schools 'allow the sale of debt to debtor' agreement, and (C) 'The third opinion is that the sale of debt to non-debtors is permissible' PRESENT character-for-character on re-fetch. Both fetched as plain HTML via WebFetch. THE RIBA LINK IS DIRECTLY SOURCED, NOT REASONED: source 1 caps the money-price of a debt at face value; source 2 records the market trading debt at a discount for cash; the collision between those two verbatim quotes IS the riba objection (a discounted money-claim sold for money = money-for-more-money across time). TRUST 'medium' (an industry-body glossary + a peer-reviewed journal reproducing standard fiqh positions; NOT a primary classical Arabic fiqh text read directly, and NOT an AAOIFI/OIC/SAC-BNM resolution read directly). DELIBERATELY DROPPED / NOT ASSERTED per the no-fabrication rule: (a) the widely-repeated 'Malaysia ACCEPTS bay' al-dayn / the Middle East / Gulf REJECTS it' geographic split — it is in WebSearch summaries but the IJMAR paper on re-fetch explicitly confirmed 'No sentences exist' affirming Malaysian acceptance or Gulf rejection, so no regional ruling is claimed (the paper does tabulate some Malaysian banks using it, but that table was not quoted verbatim and no acceptance-ruling is asserted from it); (b) the Securities Commission Malaysia / Shariah Advisory Council BNM 1996 resolution, any resolution number or date — from WebSearch summaries only, not verified verbatim, dropped; (c) any Qur'an verse or hadith collection/number; (d) any AAOIFI/OIC/SAC-BNM resolution read directly; (e) any four-schools breakdown beyond the verbatim 'allow the sale of debt to debtor', any named-scholar ruling, and any market/AUM/named-bank figure. The 'capstone / ties the corpus together' framing and the murabaha/BBA/salam/istisna/'inah/tawarruq cross-references are the site's OWN structural map, reasoned from the verbatim material and clearly framed as such — not dressed up as source quotes. FRESHNESS-HONEST: all claims are structural/definitional/doctrinal or verbatim source quotes; no dated news claim is made. JSON-only per the established article convention (content/articles/*.json feed app/lib/corpus.ts via readdirSync + the /corpus stats badge + Phase-2 retrieval; NOT rendered as individual routed cards), so no SourceCard/route/href added and internal-link integrity is unaffected. Articles 63->64. NEXT natural candidate for a future run: 'URF vs SHART (custom vs stipulated condition), or bay' al-wafa (sale with right of redemption, a near-relative of 'inah), or a fetchable-verbatim AAOIFI/OIC/SAC-BNM primary resolution on a SPECIFIC contract IF one surfaces (prior runs hit 403s) — each still needs its own two-source-verifiable pair first. PUNCH-LIST FULLY TICKED; this entry advances the sole live corpus lever.
