What is the legal ruling on dealing with usurious Algerian banks to establish institutions to confront economic colonialism and achieve self-sufficiency, given the absence of Islamic banks? Is it permissible for a university student or a young person to borrow from a usurious bank when they are unable to repay the loan within a year?

It is not permissible to deal with usurious banks for financing projects or otherwise, except in cases of extreme necessity, which is not met in this situation. The state should provide legitimate alternatives such as interest-free loans (Qard Hasan (definition)) and Murabaha. If people boycott usurious banks, these banks will be forced to open Islamic branches. Whoever borrows with usury without necessity has committed a grave sin and must repent and pay back the principal amount if possible. Otherwise, they should pay the full amount with remorse and a firm resolve not to return to such a sin.
