Is it permissible to work at a bank that includes both interest-based and non-interest-based transactions, and offers the client the option of taking an Islamic or non-Islamic loan, knowing that the work involves translation and answering customer inquiries regarding personal loans, credit cards, and car financing? If it is not permissible, is it obligatory to leave the job immediately?

If your work at the bank involves Sharia-compliant transactions, then there is no harm in it. However, if it involves prohibited commercial transactions, then it is impermissible. Similarly, even if your work is permissible, but it involves assisting in usury, even by translating or writing a contract, it is impermissible. This is based on the Almighty's saying: "And do not cooperate in sin and aggression," and the Prophet's (peace be upon him) saying: "Allah has cursed Riba (usury): its devourer, its payer, its scribe, and its two witnesses," and he said, "They are all equal."

You are obligated to immediately cease any prohibited work, unless you cannot find any other means to earn your livelihood and support those dependent on you except through this work. In such a case, you may remain in it until you find a permissible means, while diligently searching for another job. Necessity is defined as a state of danger or severe hardship from which harm to oneself or one's property is feared.

Whoever fears Allah, He will ease his affairs and provide for him from where he does not expect. The Almighty said: "And whoever fears Allah – He will make for him a way out And will provide for him from where he does not expect."
