Is it forbidden for an employee to merely sign a bank accident insurance document—without intending to benefit from it—given that she opened the bank account solely to receive her salary?

Signing a commercial accident insurance document is not permissible, because merely contracting an unlawful contract is not permissible except out of necessity. The contract must be rescinded, and one must repent.

It is not permissible to open an account in an usurious bank except in cases of necessity related to one's employer. The money must be withdrawn immediately upon deposit, and the usurious interest must be disposed of by spending it on the welfare of Muslims or by giving it as charity to the poor and needy.
