What is the ruling on dealing with financial leasing companies that purchase a commodity and register it in their name, then lease it to the client with specified profits, on the condition that ownership transfers to the client after payment of the last installment, and is this considered disguised usury?

The transaction mentioned falls under "leasing ending in ownership," which has permissible and forbidden forms. The form in which ownership is transferred automatically without a new sales contract is forbidden, as is the simultaneous execution of a lease contract and a sales contract for the same item. Permissible is a lease combined with a promise to sell or donate after the lease period ends and the full rent is paid. A condition for the permissible forms is that the lease must be genuine, meaning the responsibility for the item's guarantee and maintenance expenses lies with the lessor. There is no harm in an upfront payment deducted from the rent, but the lessor is not permitted to seize it if the term is not completed, except for the remaining period only. It is advisable to present the company's contract to specialized scholars.
