What is the value of the Sharia-compliant compensation for a female patient who suffered permanent facial hemi-paralysis due to medical error, with the doctor acknowledging that?

A skilled physician who has mastered his craft is not liable [for damages] unless there is transgression or negligence. However, if he is not skilled, or claims to be proficient in something he is not, then he is liable. Therefore, a physician is not liable if he is experienced and takes the necessary precautions. Otherwise, he is liable, and the extent of the liability is determined by referring to specialists or the Shar'i court.
