Salam finances goods that already grow; istisna finances goods that must be MADE.
Salam finances goods that already grow; istisna finances goods that must be MADE. 'Istisna (also Bia Istisna or Bai' Al-Istisna) and Bia-Salam are "forward contracts"', but 'Istisna (literally, a request to manufacture something) is a "forward contract on a project" and unlike Bia-Salam can only be a contract for something manufactured, processed, or constructed' — and crucially, in istisna 'the price need not be paid in full in advance', so 'financing payments may be made in stages to purchase raw materials for manufacturing, construction materials for construction of a building. When the product/structure is finished and sold, the bank can be repaid.' It is the manufacturing/construction contract — the last classic deferred-delivery limb of the sale family (Wikipedia, 'Islamic finance products, services and contracts')
What this source says
Salam (the forward sale, covered separately in this corpus) finances a producer of goods that essentially already exist in potential — a crop that will grow, a quantity of a standard commodity that can be sourced from anyone. Istisna finances something that does not exist at all yet and that someone must actually BUILD: a factory's output, a custom machine, a house, a power plant. The two are siblings — as the reference puts it, 'Istisna (also Bia Istisna or Bai' Al-Istisna) and Bia-Salam are "forward contracts"' — but istisna is the one tied to making rather than merely delivering. The source draws the line precisely: 'Istisna (literally, a request to manufacture something) is a "forward contract on a project" and unlike Bia-Salam can only be a contract for something manufactured, processed, or constructed.' That single restriction is what makes istisna the natural instrument of project, manufacturing and construction finance, the cases salam cannot reach. The mechanical difference from salam is the part that matters most for keeping the structure riba-free in practice, and it is the opposite of what you might expect. In salam the buyer must hand over the entire price up front; in istisna, by contrast, 'the price need not be paid in full in advance.' Because the goods take real time and labour to produce, the financing can track the work: 'Financing payments may be made in stages to purchase raw materials for manufacturing, construction materials for construction of a building. When the product/structure is finished and sold, the bank can be repaid.' So the financier is not lending money and collecting interest — it is commissioning a real thing to be made, funding the raw materials and construction inputs as they are needed, taking ownership of the finished asset, and earning its return by selling that finished asset on. The profit is the margin on a genuine manufactured or constructed deliverable that the financier procured and bore the risk on, not a guaranteed yield on a sum advanced. The contract's own flexibility reinforces that it is a real commissioning arrangement rather than a disguised loan: 'The contract may be canceled unilaterally before the manufacturer or builder starts work.' Before any work begins there is no irrevocable debt, because there is as yet no thing being made — a feature that has no analogue in an interest-bearing loan, where the obligation to repay with increase attaches the moment the money is advanced. Istisna is not a theoretical instrument. The reference records its use in live project finance: projects and residential properties financed by the Kuwait Finance House (under construction as of 2012), and — at the largest scale — the Barzan project, described in the source as 'the "biggest financing operation in the energy sector"' carried out by QatarEnergy, which 'uses Istisna and Ijara' and, as of 2013, had US$500M 'earmarked' for it. Those dated examples are reported here exactly as the source dates them, as historical illustrations of scale, not as current figures. As with murabaha and salam, honesty requires the same caveat the rest of this corpus applies to every asset-based structure: the riba-free character of istisna depends on the financier genuinely commissioning, owning and bearing the risk on a real manufactured or constructed asset; run mechanically to replicate a loan, any of these contracts can be criticised. But the underlying mechanism is sound and structurally distinct. Istisna completes the sale family: murabaha is the sale with deferred PAYMENT that finances the buyer of an existing asset; ijara is the lease of an owned asset that finances its user; salam is the sale with deferred DELIVERY that finances the producer of standard goods; and istisna is the sale of a thing-to-be-MADE that finances manufacturing and construction — letting capital reach the people who build, without anyone lending money at interest.

- School / basis
- Comparative (istisna as the manufacturing/construction contract — a forward contract for something that must be manufactured, processed or constructed, in which the price need NOT be paid in full in advance but may be financed in stages as the work proceeds, distinguishing it from salam where the full price is paid up front; the financier commissions, funds the inputs for, takes ownership of and bears the risk on a real built deliverable, earning a trading margin on that asset rather than interest on money)

Compiler’s note
First DEDICATED ISTISNA (manufacturing/construction) mechanism entry in the corpus — the deferred-delivery sale of a thing that must be MADE, the structural peer of salam (round-77, the forward sale of standard goods that finances the producer) and the natural completion of the sale family alongside murabaha (round-74, deferred-PAYMENT sale financing the buyer) and ijara (round-76, lease financing the user). Round-77 explicitly named istisna as 'the next natural mechanism-set candidate'. Grep-confirmed before writing: `ls content/articles | grep -iE 'istisna|manufactur|construct'` returned NOTHING — istisna existed in the corpus, if at all, only as a passing component, never as a dedicated entry on the manufacturing/construction instrument itself. This entry is the GENERAL MECHANISM, not a duplicate of any country/provider case. SOURCING NOTE: unlike salam (standalone 'Bai Salam' page), istisna has no clean standalone Wikipedia article — 'Istisna' 404s and 'Istisna'a' redirects — so the dedicated source is the focused Istisna section of Wikipedia, 'Islamic finance products, services and contracts'. VERIFICATION (each load-bearing fact verified BY ME on 2026-07-01 via TWO independent WebFetch reads of that page, not on a researcher's word): the 'Istisna ... and Bia-Salam are "forward contracts"' classification, the 'literally, a request to manufacture something' / 'forward contract on a project' / 'can only be a contract for something manufactured, processed, or constructed' definition-and-limit, the 'price need not be paid in full in advance' rule (the clean structural contrast with salam, where the full price IS paid up front), the 'financing payments may be made in stages ... When the product/structure is finished and sold, the bank can be repaid' staged-financing mechanism, the 'contract may be canceled unilaterally before the manufacturer or builder starts work' flexibility, and the Kuwait Finance House (2012) + Barzan / QatarEnergy (US$500M earmarked as of 2013) real-world uses ALL returned VERBATIM and CONSISTENTLY across both reads. TRUST marked 'medium' (NOT 'high'): the facts are well-corroborated but rest on an encyclopaedia entry (which itself draws on Islamic-finance jurisprudence) rather than my reading a primary AAOIFI standard or peer-reviewed source directly. DELIBERATELY DROPPED / NOT ASSERTED per the no-fabrication rule: (a) any current (2026) market-share or volume figure for istisna — none was verified, so none is asserted; the only numbers used are the source's OWN explicitly-dated examples (Kuwait Finance House 'as of 2012', Barzan 'US$500M earmarked' 'as of 2013'), reported WITH their dates as historical illustrations rather than as current facts (freshness-honest); (b) any parallel-istisna sub-structure detail not present in the verified text; (c) any claim istisna is unanimously uncontroversial — the body notes, mirroring the murabaha/salam substance-over-label caveat (the author's framing, NOT a source quote), that run mechanically to replicate a loan any of these contracts can be criticised. FRESHNESS-HONEST: the two figures are presented strictly as dated historical examples; no undated/volatile current statistic is asserted. JSON-only per the established article convention (content/articles/*.json feed app/lib/corpus.ts + the /corpus stats badge + Phase-2 retrieval; they are NOT rendered as individual cards), so no SourceCard/route added and internal-link integrity is unaffected. Articles 37->38, corpus total 135->136 (articles 38 + books 23 + youtube 23 + curated 52 = 136). With istisna added the classic deferred-delivery pair (salam + istisna) is now complete, and the core contract taxonomy — qard hasan / takaful / waqf / sukuk / murabaha / mudaraba / ijara / salam / istisna — has a dedicated mechanism entry for every limb.
