Is it permissible to give an employee's health insurance card to his sister for the treatment of her daughter, knowing that the insurance value is one and a half million?

It is not permissible to give the treatment card to the sister, due to the deception and circumvention of the company's terms involved in doing so. The Prophet, peace and blessings be upon him, said: "Whoever cheats is not one of us." One must adhere to the company's terms, for the Prophet, peace and blessings be upon him, said: "Muslims are bound by their conditions."
