What is the ruling on purchasing homes through the Islamic Bank in Jordan by means of Ijara Muntahia Bittamleek (lease ending with ownership), whereby the bank buys the house and registers it in its name, and its ownership is transferred to the buyer after the last installment is paid, with the bank taking an annual increase of 5% of the house's price?

In contracts, what matters are the meanings, not the wordings. So, if the bank conducts the transaction according to Sharia (definition) principles, including the presence of two separate contracts (leasing then selling) or a promise of ownership, and the leasing is real and not a cover for selling, then there is no harm in dealing with it. However, if the transaction is not regulated by Sharia principles and conceals usury, then it is impermissible. It is permissible for the bank to have an agreed-upon profit that does not increase with delayed payment.
