What is the ruling on a female lawyer withdrawing a bank balance that includes interest-based (usurious) earnings by proxy, and what is the ruling on the fees and expenses resulting from that?

The legal profession is permissible if it operates within the bounds of Islamic law. However, for a female lawyer to handle a case involving her client's entitlement to usurious bank interest is impermissible, as it constitutes assistance in a prohibited act and litigation in falsehood. Allah has forbidden cooperation in sin and aggression, and arguing on behalf of traitors, or being an adversary to them. Taking payment for such work is also prohibited. Furthermore, some scholars view the legal profession as forbidden for women due to the mixing with men and exposure involved.
