• Islamic banking;
• project financing;
• industrial manufacturing; and
• ṣukūk structuring.

Istisnā‘ is especially suitable for:
assets that need to be manufactured, constructed, or developed according to specific requirements.
This is because the contract allows:

• future construction/manufacturing;
• flexible payment arrangements; and
• delivery at a future date.

Q2: What types of projects commonly use istisnā‘ financing?
Answer
Istisnā‘ is commonly used in financing:

• housing construction;
• infrastructure development;
• industrial manufacturing;
• advanced technology industries.

Examples include manufacturing or construction of:

• aircraft;
• automobiles;
• ships;
• factory equipment;
• buildings;
• roads;
• bridges.

Q3: Why is istisnā‘ suitable for construction and manufacturing industries?
Answer
Istisnā‘ is suitable because:

• the asset does not need to exist at contract formation;
• assets can be custom-built according to specifications;
• payment can be:
  • progressive;
  • deferred;
  • or upfront.

This flexibility makes istisnā‘ highly practical for:

• long-term projects;
• engineering industries;
• infrastructure financing.

Case Study 1: Housing Construction Financing
An Islamic bank finances the construction of residential houses through istisnā‘.
Contract Details

• Construction of 50 houses
• Total project value = RM25,000,000
• Construction period = 3 years

Structure
First Istisnā‘ Contract
Between:

• home developer;
• Islamic bank.

The bank agrees to deliver completed houses.


Second Istisnā‘ Contract (Parallel Istisnā‘)
Between:

• Islamic bank;
• construction company.

The contractor constructs the houses.
Construction Cost
RM22,000,000


Bank’s Profit Calculation
25{,}000{,}000 - 22{,}000{,}000 = 3{,}000{,}000
25{,}000{,}000 - 22{,}000{,}000 = 3{,}000{,}000
Analysis

• Houses are constructed according to specifications.
• Parallel istisnā‘ structure used.
• Common application in Islamic banking.

Case Study 2: Aircraft Manufacturing Financing
An airline company requires customised aircraft.
Contract Details

• Aircraft manufacturing price = RM500,000,000
• Delivery period = 5 years

The Islamic financial institution enters into:

• istisnā‘ arrangement with airline;
• parallel istisnā‘ with aircraft manufacturer.

Analysis
Istisnā‘ is suitable because:

• aircraft require future manufacturing;
• detailed specifications necessary;
• project involves long-term production.

Q4: How is istisnā‘ applied in ṣukūk structures?
Answer
Istisnā‘ is widely used in:
ṣukūk (Islamic bonds) for infrastructure and development projects.
In ṣukūk istisnā‘:

• investors finance construction/manufacturing projects;
• returns are generated from project completion and operation.

Case Study 3: Infrastructure Ṣukūk Using Istisnā‘
A government issues ṣukūk to finance construction of a highway.
Project Value
RM2 billion
Structure

• Investors subscribe to ṣukūk.
• Funds used to construct highway through istisnā‘.
• Upon completion:
  • highway may be leased using ijārah structure.

Analysis
Istisnā‘ finances:

• construction stage.

Ijārah finances:

• operational/use stage after completion.

Q5: What is an example of green ṣukūk using istisnā‘?
Answer
The world’s first green ṣukūk issued in Malaysia by:
Tadau Energy Sdn Bhd
was structured using:

• ijārah.

The ṣukūk financed:

• environmentally sustainable solar energy projects.

How the Structure Worked
Istisnā‘ Stage

• solar facilities were constructed.

Ijārah Stage

• completed facilities were leased to generate returns.

This demonstrates how:

• istisnā‘ finances creation/construction;
• ijārah monetises operational use.

Case Study 4: Green Energy Project
A renewable energy company constructs solar power facilities.
Project Cost
RM250,000,000
Structure

1. Investors fund project via ṣukūk.
2. Solar facilities constructed through istisnā‘.
3. Completed facilities leased under ijārah.

Analysis

• Istisnā‘ used during construction.
• Ijārah used after completion to generate rental returns.

This structure supports:

• sustainable financing;
• socially responsible investment.
