Is it permissible, in Islamic law, for a company that lacks the financial means to purchase a warehouse it is currently renting, to resort to a financial leasing company to acquire this warehouse, knowing that the original owner has mortgaged it to the bank, which intends to sell it at public auction?

It is not permissible to purchase a warehouse with a usurious loan from financial leasing companies.

One must resort to permissible methods such as installment purchases or lease-to-own agreements.

If the leased property is sold, its usufruct remains with the lessee until the expiration of the lease term, and the buyer owns the sold item stripped of its usufruct for that period.
