What is the ruling of the Shari'ah regarding the physician's responsibility for a newborn's arm paralysis due to his negligence in measuring the mother's abdominal size and studying the X-rays, given the possibility of the child regaining arm movement?

A doctor is held liable if he administers treatment for a disease he is not knowledgeable about, or if he exceeds the necessary measures, and this results in damage, due to his transgression or negligence. Specialized medical committees for medical errors rule on such matters. Therefore, it is not possible to conclusively determine the occurrence of transgression or negligence except by specialists.
