Is it permissible to take out a loan from usurious banks to buy a house due to the unavailability of Islamic banks and the high cost of rent, especially with the wife demanding it or divorce?

It is not permissible to take out a usurious loan to purchase a house, except in a case of necessity that entails perishment or something close to it. As long as the questioner has housing through rent, it is not permissible for him to take out a usurious loan. He must advise his wife and warn her of the consequences of dealing with usury, because the one who authorizes usury is cursed. If the wife insists on her demand, divorcing her is preferable to committing usury.
