The ruling on guarding banks that invest in what is forbidden

Question:
Is it obligatory for a Muslim, if he is confused, to urge the administrative banks to stop their disbelieving investments? Is he required to follow this command?

Answer:
Yes. The security that is under the authority of the ruler is obligatory for the soldier; he must obey the ruler. This is part of the strictness of security in the entire country, not for the sake of this specific place or this specific bank, but for the sake of the strictness of security in the country. Therefore, obeying the ruler in this matter is obligatory. A person is not held accountable for guarding the bank because he does not guard the bank for its own sake, but rather he guards the security of the country. This is an obligatory matter, and obedience to the ruler in it is obligatory. This is unlike the one who is employed by the bank, whose salary is paid by the bank for the guard duty; it is he who is held accountable. As for the one who is an employee of the state, under the authority of the ruler, and tasked with guarding the entire country, including the banks and others, this is an obligatory matter, and violating it is forbidden. One must adhere to this because it is part of obeying the rulers.
