Is it permissible to work in a usurious bank—such as a commercial bank—in order to pay off bank installments and to avoid dismissal from one's job?

Working in usurious banks is impermissible due to its being cooperation in sin. The prohibition is more severe if the work is directly related to usury, as evidenced by the Hadith: "The Messenger of Allah (peace and blessings be upon him) cursed the one who consumes usury, the one who gives it, the one who writes it, and its two witnesses, and he said: 'They are all alike.'" The claim of necessity to work in usurious banks is only valid if there is no other lawful work available, along with fear of imprisonment or harm for not repaying debts. This permissibility ceases when the necessity no longer exists. A debt owed to an Islamic bank does not permit working in a usurious bank, because an Islamic bank is not permitted to imprison an insolvent debtor; rather, it must grant him a reprieve or pardon him.
