Is it permissible to buy a house through the bank for a large family that is struggling to find suitable housing?

It is not permissible to take out a usurious loan to purchase a home, except in cases of extreme necessity, such as the impossibility of finding a rental property without enduring unbearable hardship, and the unavailability of halal methods for purchasing, like an interest-free loan (Qard Hasan) or permissible transactions. And whoever fears Allah and relies upon Him, He will provide for him from where he does not expect.
