What is the ruling on fixed interest from usurious banks in the absence of Islamic banks and the fear of losing money?

It is not permissible to deposit money in interest-based banks, even for safekeeping, because it constitutes aiding in sin. If a Muslim is compelled to deposit his money in an interest-based bank due to the absence of an Islamic bank, he should deposit it without interest. If this is not feasible, he should take the interest and spend it on charitable causes and for the benefit of Muslims, and not leave it for the bank.
