What is the legal punishment that can be inflicted upon a lawyer who exploited his influence and wrongfully seized his clients' money, and threatened them with martyrdom in defense of their wealth if they are not treated justly?

The questioner is advised to try to ward off harm by complaining to someone who will do him justice and is able to remove the injustice from him, even if it means paying some money to secure most of it. This is not the forbidden bribery; rather, it is like a permissible ju'alah (a contract for a specified reward for a specific task) if he is wronged. As for fighting the aforementioned person, it entails the loss of both money and life. Therefore, this idea must be completely abandoned, and an attempt should be made to ward off harm and remove injustice through the aforementioned methods.
