What is the ruling on owning a house through a "housing program" with an Ijara (leasing) contract ending with a promise to sell, knowing that in the event of delay in paying the monthly installments, a late fee will be imposed, which will be spent on charitable purposes and will not be included in the bank's profits?

The contract included an usurious condition, which is the "fine" or "fee" imposed by the bank on the client for late payment of an installment. Naming it a "fee" or allocating it to charitable organizations does not make it permissible. It is not lawful for the creditor to increase the debt in any way due to the debtor's delay.

As for "lease-to-own contracts" and "financing against real estate," judging them requires knowledge of their details, as this type of contract has impermissible forms and permissible ones.
