Will Salaah be Valid if Performed in a House Built with Interest Money?

Q: Salaah-105: Most of the people here in England own their homes and almost all have been bought through a building society, meaning that the money to buy the house has been borrowed on interest. Is salaah valid in such a house?

Answer: While salaah will be valid if performed in a house built with a loan from a building society, it will be best to perform it in a place where there is no doubt about it being built in this manner. And Allaah knows best what is most correct.
