What is the ruling on benefiting from financial compensation obtained based on a medical report containing errors and inaccurate diagnoses of some injuries, knowing that some of the injuries mentioned in the report are correct, and that the lawyer took 25% of the compensation amount?

It is not permissible to rely on a false report to submit to the insurance company, and any amount exceeding what is due must be returned, as Allah Almighty says: "And do not consume one another's property wrongfully." The Muslim must repent from this. The lawyer is entitled to the agreed-upon fee as a percentage, but from the actual amount due, not from the amount taken wrongfully. If egregious exploitation is proven in the hiring, the lawyer is entitled to the customary fee.
