Bay al-Inahبيع العينة

A sale-and-buy-back arrangement in which a party sells an asset on credit and immediately repurchases it for cash at a lower price, with the cash difference functioning as a loan with a built-in mark-up. Treated very differently across schools and jurisdictions.

What bay al-inah is

Bay al-Inah (بيع العينة) is a sale-and-buy-back arrangement in which the same two parties enter into two linked transactions: party A sells an asset to party B on credit at one price, and immediately repurchases the same asset from B for cash at a lower price. The economic effect is that B receives cash today and owes A a higher amount on a deferred date — functionally a loan with a built-in mark-up. The asset itself is incidental; it never leaves A's possession in any operational sense.

The modern controversy is what the classical sources cited above already grappled with: is the asset-leg a genuine sale, in which case the structure is a permissible chain of two sales, or is the asset a fig leaf for what is in substance a riba transaction, in which case the structure is impermissible regardless of the formal contracts?

The split in contemporary scholarship

Contemporary scholarship is meaningfully divided on bay al-inah, in a way that few other fiqh-finance topics are. The cited sources reflect the divergence:

  • Majority position (Hanafi, Shafi'i, Maliki, Hanbali — and AAOIFI in standard practice). The structure is impermissible because the second leg is pre-arranged with the same counter-party, which converts the chain into a riba-bearing loan in substance. The hadith narrated in Sunan Abi Dawud 3461 — prohibiting the combining of two sales in a way that operates as a hidden loan — is the classical anchor.
  • Bank Negara Malaysia historical position. The Shariah Advisory Council of Bank Negara Malaysia historically permitted bay al-inah as a domestic Islamic-banking instrument under specified conditions. This position has been progressively narrowed over the past decade, and several major Malaysian Islamic banks have moved away from inah-based products toward tawarruq and other structures.
  • OIC Fiqh Academy Resolution No. 179 (2009). The Academy ruled the structure impermissible at the international-fiqh level, citing the hadith above and analysing the contract chain as substantively riba.

The practical effect is that Gulf, North-African, and OIC-aligned institutions treat bay al-inah as impermissible; some Malaysian institutions historically treated specific narrowly-conditioned versions as permissible domestically; and the international academic-fiqh body has issued the impermissibility ruling at the highest level of formal authority available below national fatwa councils.

How bay al-inah differs from tawarruq

The two structures look similar at a glance and are often confused. The cited AAOIFI source draws the distinction explicitly:

  • Bay al-inah: Two parties, same asset, sale and immediate buy-back between them.
  • Tawarruq: Three (or more) parties. Buyer purchases an asset on credit, takes possession, then sells the asset to a third party for cash. The cash recipient never sells the asset back to the original seller.

Tawarruq is itself controversial — see the dedicated entry — but it is structurally a different shape. Substituting one for the other does not resolve the underlying objection unless the structural change is real (third party, real possession, no pre-arranged buy-back).

Where this fits relative to HalalCrypto

HalalCrypto does not offer credit, financing, or any sale-and-buy-back structures. The reason bay al-inah appears in this glossary is that occasionally a DeFi product is described as "halal credit" or "Shariah-compliant lending" with structural features that map onto an inah-shape on inspection. Subscribers who want to evaluate such products against the published AAOIFI and OIC Fiqh Academy positions can use the entry above as a starting reference. The platform's screening posture and the pages that document it — /halal-methodology and the cornerstone framework page — apply the AAOIFI alignment that follows the majority position cited above.

Quick reference

  • Sale-and-buy-back between two parties; cash leg is the substance, asset leg is formal.
  • Treated as impermissible by AAOIFI standard practice, all four classical schools, and OIC Fiqh Academy Resolution 179.
  • Historically permitted in narrow conditions by some Malaysian institutions; this position has been progressively narrowed.
  • Distinct from tawarruq, which adds a third party and shifts the structural analysis.
