What is the ruling on not resuscitating a case that is medically hopeless, and is it permissible to issue a written order not to resuscitate in the medical file, and is it necessary to inform the family of this? What are the fatwas of the Fiqh Councils or the Permanent Committee regarding this matter?

If only one resuscitation device is available, and two individuals are presented—one whose life is despaired of and the other for whom recovery is hoped—the one for whom recovery is hoped should be prioritized. However, if the device is available for everyone, or if the individual whose life is despaired of has already been connected to the device, it is not permissible to remove it, as that would be considered killing. Despairing of recovery is despairing of Allah's mercy, and Allah the Almighty said: ("And who despairs of the mercy of his Lord except those astray?"). The Prophet, peace and blessings be upon him, said: ("There is no disease for which Allah has not sent down a cure.") As for a doctor's decision not to resuscitate, it follows the ruling on the permissibility or impermissibility of foregoing resuscitation, and there is no obligation to inform the family unless doing so would lead to harm.
