Trade & Partnership Finance — Salam, Istisna'a, Mudaraba, Musharaka
In Lesson 7, you worked through takaful — Islamic insurance — and the IFRS 17 challenges it creates. Lessons 4 through 7 each focused on a single product: murabaha, ijarah, sukuk, and takaful. Those four products represent the majority of Islamic banking balance sheets, but four important product types remain: salam (advance purchase), istisna'a (construction finance), mudaraba (profit-sharing investment), and full musharaka (joint venture). These are the products that fund commodity trading desks, infrastructure projects, and investment pools — and they introduce accounting mechanics that murabaha and ijarah do not.
This lesson covers all four in two pairs. The first pair — salam and istisna'a — are trade finance products where the bank funds the purchase or construction of a tangible asset. The second pair — mudaraba and musharaka — are partnership finance products where the bank provides capital and shares in the profit or loss of the venture. Each pair shares structural similarities that make them easier to learn together than in isolation.
Trade Finance: Salam (AAOIFI FAS 7)
Salam is the mirror image of murabaha. In murabaha, the bank buys an asset today and sells it to the customer at a mark-up with deferred payment. In salam, the bank pays the full price in advance for a commodity that will be delivered at a future date. The bank bears the commodity price risk between payment and delivery.
Four Shariah requirements must be satisfied:
| Requirement | Detail |
|---|---|
| Full advance payment | The bank must pay the entire price at contract date — no staged payments permitted |
| Fungible commodity | The subject must be a commodity describable by specification (wheat, steel, oil) |
| Precise delivery | Delivery date, location, and quality specifications must be fixed |
| May not yet exist | Unlike murabaha, the commodity need not exist at contract date |
Step 1 — Advance payment at contract date: Dr: Salam Receivable | Full contract price Cr: Cash | Full contract price
Step 2 — Commodity delivered at maturity: Dr: Salam Commodity (Inventory) | Fair value at delivery Cr: Salam Receivable | Contract price (Any difference = gain or loss recognised immediately)
Step 3 — Bank sells the commodity: Dr: Cash | Sale proceeds Cr: Salam Commodity | Carrying amount Cr/Dr: Gain or Loss on Salam | Difference
Parallel salam: The bank can hedge by entering a second salam as seller of the same commodity to a third party. The two contracts must be legally independent — linking them creates a prohibited back-to-back arrangement.
Trade Finance: Istisna'a (AAOIFI FAS 10)
Istisna'a is the Islamic equivalent of construction finance. The bank contracts to have an asset manufactured or constructed and delivers it to the customer. Unlike salam, payment may be deferred or staged — the customer can pay in milestones as construction progresses.
The critical accounting difference from all other Islamic products is revenue recognition. Istisna'a uses the percentage of completion method — arithmetically identical to IFRS 15 over-time recognition. The AAOIFI-specific requirement is that each milestone must include an explicit Shariah compliance confirmation alongside the financial measurement; IFRS 15 does not require this.
| Element | AAOIFI FAS 10 | IFRS 15 |
|---|---|---|
| Revenue method | Percentage of completion | Over-time recognition |
| Milestone confirmation | Financial + Shariah compliance | Financial only |
| Loss-making contracts | Recognise full expected loss immediately | Same — IAS 37 / IFRS 15 onerous rules |
| Parallel istisna'a | Gross presentation (doubles balance sheet) | Same — principal vs agent assessment |
In a parallel istisna'a, the bank sits between the customer and the contractor. The bank has an istisna'a contract with the customer (selling the completed asset) and a separate istisna'a contract with the contractor (commissioning the build). Both contracts must be independent. Parallel istisna'a usually requires gross presentation on the balance sheet — the bank recognises both the asset under construction and the receivable from the customer, which can significantly increase balance sheet size.
Partnership Finance: Mudaraba (AAOIFI FAS 3)
Mudaraba is the foundational partnership structure in Islamic banking. Two parties are involved: the rabb ul mal (capital provider, who bears all financial loss) and the mudarib (manager, who provides labour and expertise). In banking, the investment account holders (IAH) are the rabb ul mal and the bank is the mudarib.
The critical accounting mechanic is the profit pool calculation. This is the engine that determines how much each party receives:
| Step | Calculation |
|---|---|
| 1 | Total income from mudaraba pool |
| 2 | Allocate between bank's own funds and IAH funds |
| 3 | Apply mudarib (bank) share to IAH pool (e.g. 30% to bank) |
| 4 | Apply weightages by account type (3-month, 6-month, 12-month) |
| 5 | Deduct PER and IRR contributions |
| 6 | Final distribution to each IAH tier |
Two reserve mechanisms smooth returns:
- PER (Profit Equalisation Reserve): Portion of gross income set aside before distribution. Smooths returns across periods so IAH don't see volatile month-to-month fluctuations.
- IRR (Investment Risk Reserve): Portion of IAH income set aside as buffer against future capital losses. Protects IAH principal without violating the mudaraba rule that the capital provider bears loss.
Balance sheet treatment: IAH funds appear as "Equity of Investment Account Holders" — a separate category between liabilities and equity. This is unique to Islamic banks; conventional bank balance sheets have no equivalent line item.
Partnership Finance: Full Musharaka (AAOIFI FAS 4)
In full musharaka, all parties contribute capital and management. Profits are shared per an agreed ratio (which may differ from the capital ratio). Losses are shared strictly in proportion to capital — this is a non-negotiable Shariah rule.
| Musharaka Type | Structure |
|---|---|
| Permanent | Indefinite joint venture — all parties remain invested |
| Running | Short-term revolving arrangement — capital recycled |
| Diminishing | Gradual buy-out (covered in Lesson 5 under ijarah IMB) |
Initial investment: Dr: Musharaka Investment | Capital contributed Cr: Cash | Capital contributed
Period-end profit: Dr: Accrued Profit Receivable | Bank's share of profit Cr: Income from Musharaka | Bank's share
Period-end loss: Dr: Loss from Musharaka | Bank's capital proportion of loss Cr: Musharaka Investment | Bank's capital proportion (reduces carrying value)
Key rule: Losses reduce the carrying value of the musharaka investment. A sustained loss will eventually write the investment down to zero.
IFRS classification challenge: Most musharaka arrangements fail the SPPI test (Solely Payments of Principal and Interest) under IFRS 9. Musharaka returns are profit shares, not interest — they depend on the venture's performance, not a contractual rate. This means musharaka investments are typically classified at FVTPL (Fair Value Through Profit or Loss) under IFRS, requiring mark-to-market accounting. Under AAOIFI FAS 4, musharaka investments are carried at historical cost adjusted for the bank's share of undistributed profit or loss — a fundamentally different measurement basis.
Comparing All Four Products
| Feature | Salam | Istisna'a | Mudaraba | Musharaka |
|---|---|---|---|---|
| AAOIFI standard | FAS 7 | FAS 10 | FAS 3 | FAS 4 |
| Payment timing | Full advance | Staged / deferred | Capital upfront | Capital upfront |
| What bank provides | Cash for commodity | Construction financing | Capital (no management) | Capital + management |
| Revenue method | Gain/loss on resale | % of completion | Profit pool distribution | Agreed profit ratio |
| Loss bearing | Commodity price risk | Construction cost risk | Rabb ul mal (100%) | By capital proportion |
| IFRS interaction | IAS 2 / IFRS 9 | IFRS 15 | IFRS 9 (complex) | IFRS 9 FVTPL + IFRS 11 |

Practice Exercise 5: Trade & Partnership Finance — Construction Project Across Jurisdictions
What you will build: A multi-product accounting package for a single construction project that uses all four products — istisna'a for construction, parallel salam for materials, mudaraba for investment capital, and musharaka for equity participation.
Requirements: Cowork or Claude (any plan). 45 minutes.
Scenario: A UAE construction company needs to build a hospital complex worth AED 200 million. The Islamic bank structures the financing using a combination of istisna'a (construction phase) and parallel salam (materials procurement). An investment fund provides mudaraba capital (AED 80M) and the bank and a partner each contribute AED 60M in a musharaka arrangement for the remaining equity.
-
Istisna'a accounting (UAE — IFRS). Tell your AI assistant: "I am working on a UAE entity using IFRS. Structure an istisna'a contract for a hospital construction project worth AED 200 million. Apply IFRS 15 over-time recognition with three milestones (30%, 60%, 100% completion). Generate the journal entries at each milestone, including the revenue and cost recognition. Show the parallel istisna'a gross presentation on the balance sheet."
-
Parallel salam (Bahrain — AAOIFI FAS 7). Tell your AI assistant: "The materials supplier is in Bahrain. The bank enters a salam contract paying AED 25 million in advance for steel and construction materials to be delivered in 6 months. Generate the salam receivable entries under AAOIFI FAS 7 — advance payment, delivery, and resale to the construction project at AED 26.5 million. Then show the parallel salam where the bank hedges by entering a second salam as seller."
-
Mudaraba distribution. Tell your AI assistant: "The investment fund provides AED 80 million as rabb ul mal. The bank is mudarib with a 25% mudarib share. The pool has three account types with weightages: 3-month deposits (weight 0.70), 6-month deposits (weight 0.85), 12-month deposits (weight 1.00). Total pool income is AED 6.2 million. PER contribution is 2% of gross income; IRR is 1% of IAH share. Calculate the complete profit distribution showing each step of the six-step process."
-
Musharaka accounting. Tell your AI assistant: "The bank and a partner each contribute AED 60 million in a musharaka arrangement. Agreed profit ratio: 55% bank, 45% partner. Loss ratio: 50/50 (by capital). Generate the initial investment entries, a period-end profit of AED 8 million, and then a subsequent period loss of AED 3 million. Show how the loss reduces the carrying value of each partner's investment."
-
Comparison summary. Tell your AI assistant: "Produce a single-page summary showing how all four products interact in this one hospital construction project. For each product, show: which AAOIFI standard governs, which IFRS standard applies, the key accounting entries, and where the jurisdiction overlay changes the output. Identify which product creates the largest balance sheet impact and explain why."
Check your work: Step 1 should use IFRS 15 over-time recognition with revenue matching cost progression at each milestone. Step 2 should carry the salam receivable at cost (AED 25M) until delivery, with a gain of AED 1.5M on resale. Step 3 should show PER deducted from gross income before the mudarib share, and IRR deducted from IAH net income. Step 4 should show the loss of AED 3M split 50/50 regardless of the profit ratio. Step 5 should demonstrate that the same project triggers four different product skills with different accounting standards governing each.
Salam is most commonly used in commodity-rich jurisdictions — Bahrain, Sudan, and parts of Southeast Asia. Agricultural salam (wheat, rice, palm oil) and metals salam (steel, aluminium) are the dominant structures.
Istisna'a is the backbone of Islamic infrastructure finance. The UAE, Saudi Arabia, and Malaysia have all used istisna'a structures for major construction projects. In Malaysia, istisna'a often appears alongside sukuk al-istisna'a — construction-backed Islamic bonds.
Mudaraba is universal — every Islamic bank uses it for investment account structures. The profit pool calculation varies by jurisdiction: Malaysian banks tend to use simpler weightage tables; Gulf banks often use more granular multi-tier structures.
Musharaka in its full form is less common in retail banking but critical in corporate and project finance. Diminishing musharaka (covered in Lesson 5) is far more prevalent in retail — particularly for home finance in the UK and Malaysia.

Prompt 1: Salam vs Istisna'a Decision
A client needs financing for a large order of industrial equipment.
The equipment will be manufactured over 8 months and delivered in stages.
Questions:
1. Should this be structured as salam or istisna'a? Explain the
key structural differences that determine the choice.
2. What are the payment timing implications of each structure?
3. If the bank chooses istisna'a, how does percentage of completion
revenue recognition work? Show a simple 3-milestone example.
4. If the bank chooses salam, why must payment be made in full
upfront — and what risk does the bank bear?
5. Under what circumstances would parallel salam or parallel
istisna'a be appropriate?
Work through this for a UAE entity using IFRS.
What you are learning: The choice between salam and istisna'a is one of the most important structuring decisions in Islamic trade finance. Salam requires full advance payment and works for fungible commodities; istisna'a allows staged payment and works for manufactured or constructed assets. Understanding when to use each — and the risk profile each creates — is a core competency for Islamic finance practitioners.
Prompt 2: Mudaraba Profit Pool Worked Example
An Islamic bank has the following mudaraba investment pool:
- Total pool: AED 500 million
- Bank's own funds in pool: AED 100 million
- IAH funds: AED 400 million
- Mudarib share: 30%
- Account types:
- Savings (weight 0.60): AED 150 million
- 6-month term (weight 0.85): AED 150 million
- 12-month term (weight 1.00): AED 100 million
- Total pool income: AED 28 million
- PER rate: 2.5% of gross income
- IRR rate: 1.5% of IAH net income
Calculate the complete 6-step profit distribution:
1. Total income allocation (bank own funds vs IAH)
2. Mudarib share deduction
3. PER deduction
4. Weightage-based allocation across tiers
5. IRR deduction per tier
6. Final distribution per AED of each tier
Show all intermediate calculations.
What you are learning: The mudaraba profit pool is the engine of Islamic deposit-taking. Unlike conventional interest calculation (straightforward rate x principal x time), mudaraba distribution involves a multi-step waterfall with reserves. PER smooths returns across periods; IRR protects capital. Understanding this calculation is essential because it drives the returns that IAH actually receive — and it is the primary source of Shariah audit findings when banks make errors in weightage application or reserve calculations.
Prompt 3: Musharaka IFRS Classification Challenge
A bank enters a musharaka arrangement with a real estate developer:
- Bank contributes 60% of capital
- Developer contributes 40% of capital
- Profit sharing: 55% bank, 45% developer
- Loss sharing: 60/40 (by capital ratio, mandatory)
- Expected duration: 5 years
Analyse this arrangement under IFRS:
1. IFRS 11 classification: Is this a joint operation or joint venture?
What factors determine the answer?
2. IFRS 9 classification: Apply the SPPI test to the bank's
musharaka investment. Does it pass or fail? Why?
3. If SPPI fails, the investment goes to FVTPL. What does this
mean for the bank's income statement volatility?
4. Compare with AAOIFI FAS 4: How would the same arrangement
be measured? What are the practical differences in reported
profit between IFRS FVTPL and AAOIFI historical cost?
5. Why does the profit ratio (55/45) differ from the loss ratio
(60/40)? What Shariah rule governs each?
This is a jurisdiction overlay question: the same arrangement
produces different financial statement impacts depending on
whether AAOIFI or IFRS governs.
What you are learning: Musharaka is where the Islamic finance and IFRS frameworks diverge most sharply. The SPPI test was designed for conventional debt instruments — principal plus interest. Musharaka returns are profit shares that depend on the venture's performance, which is fundamentally different from contractual interest. This means most musharaka investments end up at FVTPL under IFRS, creating income statement volatility that does not exist under AAOIFI. Understanding this divergence is critical for any practitioner working across jurisdictions.
