Is it permissible to take out a loan with interest from a British bank in order to buy a house?

If the bank owns the house, it is permissible to sell it for a known deferred or installment price, even if the price is higher than its cash value. However, if the bank is a financier lending you the price of the house with an increase, then this is a forbidden usurious transaction. A Muslim must be patient and seek what is lawful, in accordance with the Almighty's saying: "And whoever fears Allah - He will make for him a way out (2) And will provide for him from where he does not expect. And whoever relies upon Allah - then He is sufficient for him. Indeed, Allah will accomplish His purpose. Allah has already set for everything a [decreed] extent (3)" [Surat Al-Talaq].
