This study examines how the concepts of biomedical ethics are considered in Islam and how historical Islamic medical scholars treated the concept of ethics in their practice of medicine. Moreover, this research explores the principle of autonomy in biomedical ethics as a factor in Islamic practice of medicine. The issue of autonomy in medical practice is an important topic of discussion requiring examination of the methods of its adaptation and application in Muslim-majority countries. The value and significance of this topic continues at a global level, involving Muslim communities in Non-Muslim countries experiencing religious and social diversity. The fieldwork of this study was conducted in Turkey, Jordan and Gaza Strip, Palestine, investigating the subject matter with practitioners in health care sectors as well as with leading academics, researchers, non-government organizations and policymakers. The results indicate that the principle of autonomy is not fully implemented in the three countries from an Islamic perspective. / 博士(グローバル社会研究) / Doctor of Philosophy in Global Society Studies / 同志社大学 / Doshisha University
