Fiqh al-Ijara al-Muntahiya bil-Tamlik (فِقهُ الإِجَارَةِ المُنتَهِيَةِ بِالتَّملِيك — Jurisprudence of the Lease Ending in Ownership Transfer; *ijara*: lease; *muntahiya*: ending; *bil-tamlik*: with ownership transfer; abbreviated: IMBM; this is Islamic finance's equivalent of a lease-to-own or finance lease; basic structure: [1] the bank [lessor] owns an asset [real estate, machinery, vehicle, aircraft]; [2] the customer [lessee] leases the asset for a specified period and makes periodic lease payments [ujrah]; [3] at the end of the lease period, ownership of the asset transfers from the bank to the customer; ownership transfer methods: the method of ownership transfer at lease end is a critical jurisprudential issue: [a] sale at a nominal price [token price at end]: the bank sells the asset to the customer at a very low/token price at lease end; [b] gift [hiba]: the bank gifts the asset to the customer at the end of the lease term; [c] gradual transfer: ownership transfers incrementally with each payment [diminishing musharaka approach]; [d] sale at market value: the customer has the right but not obligation to purchase at fair market value; the critical Islamic jurisprudential requirement: the ownership transfer must NOT be a contractual condition of the lease itself; the lease and the ownership transfer must be TWO SEPARATE CONTRACTS [or a separate binding promise]; this is because: [1] classical fiqh prohibits combining a sale and a lease in a single contract [for the same subject matter]: 'two contracts in one' [safqatayn fi safqa] is prohibited; [2] the lessee must not be paying rent that is actually disguised purchase instalments [this would be functionally interest]; how IMBM differs from a conventional finance lease: a conventional finance lease typically makes the lessee's obligation to purchase at the end a condition of the lease itself; this contractual pre-commitment is what Islamic scholars find problematic; in IMBM, the bank makes a separate [unilateral] binding promise [wa'd] to transfer ownership at end; the lessee is not contractually bound to purchase; the wa'd [promise] and its binding force: a key debate: is a binding wa'd [promise] the same as a contract? Classical fiqh says a wa'd is not a contract [only morally binding]; AAOIFI Standard 9 and AAOIFI Shari'a Standard No. 49 address this; in IMBM, both parties' promises about the end-of-lease disposition are usually treated as binding [muljim] for practical Islamic banking purposes; AAOIFI Standard 9 on IMBM: sets out the conditions for valid IMBM; key requirements: [1] the lease and ownership transfer must be in separate documents or contracts; [2] the lease payments must represent genuine rental for genuine use; [3] the bank must bear ownership risks during the lease period [e.g. loss or destruction of the asset — the bank can't make the lessee responsible for major losses of the asset itself]; [4] the asset must be genuinely Islamically acceptable; practical uses: [1] home financing: Islamic mortgage equivalent; the customer leases the house from the bank and at the end owns it; [2] auto financing: car leasing with transfer; [3] equipment financing: industrial machinery; [4] aircraft and ship financing; the IMBM vs murabahah comparison: murabahah [cost-plus sale] involves immediate ownership transfer; IMBM involves deferred ownership through leasing; IMBM is often preferred for long-term assets where immediate ownership transfer is impractical) is Islamic banking's primary lease-based financing structure.
The Lease That Ends in Ownership
The ijara al-muntahiya bil-tamlik (IMBM) is Islamic banking’s answer to the conventional finance lease: a structure where a customer wants to end up owning an asset but cannot or does not want to buy it outright. They lease it, make payments, and ownership eventually transfers.
The critical Islamic jurisprudential constraint is that the ownership transfer cannot be contractually locked in from the start. Classical Islamic law prohibits combining a lease and a sale of the same asset in a single contract — this would make the lease payments functionally equivalent to purchase instalments disguising an interest-bearing loan. The two transactions (the lease, the eventual ownership transfer) must be formally separate.
The Separate Promise Problem
The practical mechanism for making IMBM work is the wa’d (binding promise): the bank makes a separate, unilateral, binding promise to transfer ownership at the end of the lease on agreed terms. The customer makes a separate commitment to exercise the purchase option. These are promises, not contract conditions of the lease itself.
Whether a wa’d is truly distinct from a contract is one of Islamic finance’s most debated questions. Classical fiqh treats a promise as morally binding but not legally enforceable in the way a contract is. Modern Islamic banking practice — codified in AAOIFI Standard 9 — has developed a position that unilateral promises (wa’d) in financial contexts are binding for both practical and ethical reasons.
Who Bears the Risk?
AAOIFI’s requirements for IMBM include a provision that distinguishes it from a disguised loan: the bank (as owner) must bear the major ownership risks during the lease period. If the asset is destroyed through no fault of the lessee, the bank bears the loss — not the lessee. This risk-bearing by the bank (which also receives the rental income) is what makes the bank’s role genuinely ownership rather than loan-with-collateral.
