Fiqh al-Ijarah al-Muntahiyya bi-l-Tamlik — Lease Ending in Ownership: The Most Common Islamic Alternative to the Conventional Mortgage, Where a Bank Purchases Property and Leases It to the Customer, With Ownership Gradually Transferring to the Customer Through Separate Sale Agreements or Gift Transfers, the AAOIFI Standards on Structuring It Correctly, and Why the Simultaneous Combination of Lease and Sale in One Contract Is Prohibited in Classical Fiqh

Fiqh al-Ijarah al-Muntahiyya bi-l-Tamlik (فِقهُ الإِجَارَةِ المُنتَهِيَةِ بِالتَّملِيك — Jurisprudence of the Lease Ending in Ownership; *ijarah*: from *a-j-r*: to hire, to rent; ijarah = lease, rental contract; *muntahiyya*: ending; *tamlik*: transfer of ownership; full phrase: the lease that ends in [transfer of] ownership; also known as: *ijarah wa-iqtina'* [lease and acquisition] or *ijarah muntahiyya bi-tamlik* [IMBT]; the basic structure: [1] Step 1: the Islamic bank [or financial institution] purchases the property from the seller; the bank is now the owner; [2] Step 2: the bank leases the property to the customer; the customer pays rent [ujrah] periodically; [3] Step 3 [at end of term]: the bank transfers ownership to the customer; this transfer happens through either: [a] a separate sale contract at a nominal price [bay' ramzi]; [b] a gift [hibah] at end of term; [c] installment sale agreements made periodically throughout the term; [4] the customer lives in the property during the lease period and 'acquires' it through the transfer mechanism at the end; comparison to conventional mortgage: in a conventional mortgage: [a] the bank lends money; the customer buys the house; the bank takes a lien; the customer repays principal + interest; Islamic IMBT: [a] the bank owns the house; the customer pays rent [not loan repayment]; [b] ownership transfers at end [not from the beginning]; [c] no riba — the return to the bank is rent income from asset ownership, not interest on a loan; the classical prohibition violated in bad IMBT structures: classical fiqh prohibits two contracts in one [bay'atayn fi bay'ah — two sales in one]; specifically: the combination of lease and sale in a single contract; if the lease contract contains a binding promise to sell at the end, or if the sale is a condition of the lease, the combined contract may constitute a prohibited combination; the AAOIFI solution: AAOIFI [Accounting and Auditing Organization for Islamic Financial Institutions] Standard 9 addresses IMBT; key requirements: [1] the lease and the sale [or gift] must be separate contracts; they cannot be combined in one document or made conditional on each other; [2] the bank must genuinely own the property during the lease period and bear ownership risks [like major structural damage, as distinct from maintenance costs which go to the lessee]; [3] the rent amounts must not be structured to disguise what is functionally an interest payment; the rent must be an actual market rent for use of the property; [4] the promise to sell [wa'd bi-l-bay'] at the end can be binding [mulzim] on one party but must not be a bilateral binding promise that makes the contract combination equivalent to a combined lease-sale; the Diminishing Musharakah alternative: an alternative to IMBT is *musharakah mutanaqisah* [Diminishing Partnership], where bank and customer co-own the property from the start, and the customer gradually buys out the bank's share; regulatory adoption: IMBT is approved by Shariah boards in Malaysia, GCC countries, and many Western Islamic finance institutions; it is the primary Islamic home finance structure in the UK, Canada, Australia, and the United States among Muslim home-buyers seeking shariah-compliant financing) is the primary vehicle through which Muslim families in Western countries finance home ownership.
