Is it permissible to undertake a mortgage operation for usurious loans if the employee is compelled to do so and cannot refuse?

Pledging in debt is originally permissible, as it is established that the Prophet, peace and blessings be upon him, bought food on credit and mortgaged his shield with a Jew. However, if the transaction is forbidden, such as an interest-based loan, it is not permissible to secure the contract with a pledge or anything else, otherwise your effort in that would be assisting usurers.

If your work in the aforementioned institution is permissible and has no connection to interest-based loans, then there is no harm upon you. Otherwise, you must refrain from it, unless necessity or a recognized need compels you to remain in it, such as not finding any other work to earn a livelihood. In that case, you are permitted to stay while searching for permissible work.
