What is the status of a lawyer in the Islamic judicial system, given that he strives by every means to obtain a ruling in favor of his client?

In Islamic jurisprudence, a lawyer acts as an agent for their client. Both the lawyer and the client are obligated to seek justice and treat the opponent fairly. If they adhere to this, it will be better for them and an aid to the judge. However, if they pursue falsehood and unlawful gain, they incur sin, consume people's wealth unjustly, and cause confusion for the judge.
