Is the death of a patient considered accidental homicide because the doctor administered an intravenous painkiller too quickly, without prior knowledge of its danger? What rulings apply to the doctor, such as paying blood money (diyah) or retribution (qisas)? And how can the cause of death be determined?

If a physician makes an error in prescribing medication or its administration, leading to the patient's death or the damage of an organ, he is liable for guarantee (diyah and expiation). An ignorant physician, or one who errs in prescribing medication, or exceeds the accepted limits, is considered liable. To ascertain your responsibility, the details of the case must be presented to three trustworthy cardiologists. If they concur that your method of administering the painkiller was the cause of death, then guarantee becomes incumbent upon you. The diyah is paid by the 'Aqilah (the male relatives on the paternal side), while the expiation is fasting for two consecutive months.
