Is it permissible to delay payment of a portion of the apartment's price to the seller in installments after the Murabaha contract with the Islamic bank is completed and the apartment is received?

It is not permissible to agree with the original owner of the commodity in a Murabaha sale to declare a price other than the real price and to pay it after the bank's transaction is concluded. This is because declaring a price other than the real one is a forbidden lie, and because there is no relationship between the buyer and the original seller after the bank purchases the property. Any previous contractual agreement between the client and the original seller must be canceled. It is permissible for the Murabaha to be conducted on a portion of the property, such as two-thirds, where the bank purchases this portion and sells it to the client on a Murabaha basis, and the client purchases the remaining portion from the owner.
