What is the ruling on the Ijara-ending-in-ownership system for purchasing an apartment from an Islamic bank, and is it permissible to send a copy of the 10-page contract for Sharia review?

Lease-to-own arrangements have permissible and prohibited forms. The criterion for prohibition is the simultaneous occurrence of two different contracts for the same asset. The criterion for permissibility is the temporal separation of two contracts, such that the sale contract is concluded after the lease, or there is a promise of ownership at the end of the term, and the lease is an actual lease. Among the conditions for permissibility are also that the responsibility for the asset lies with the owner, that the insurance is cooperative Islamic insurance borne by the owner, that the rules of leasing apply throughout the lease period, and then the rules of sale apply upon ownership, and that non-operational maintenance expenses are borne by the lessor. Prohibited forms of the contract include: the automatic conversion of the lease into a sale without a new contract, a sale contract contingent on the full payment of the rent, or a lease combined with a sale with a conditional option for the lessor that is deferred. Permissible forms of the contract include: a lease combined with a gift of the asset contingent on the full payment of the rent, or a lease with the owner giving the lessee the option to purchase the asset at market price after the installments are completed, or a lease with a promise to sell the asset after the rent is paid for an agreed-upon price, or a lease with the lessee being given the option to own the asset at any time through a new contract at market price.
