The Islamic heritages in the medical field are not only memories of the past. But through the work of previous Islamic doctors, it is hoped that they can inspire many Muslim scientists today. Al-Razi is one of the most influential Islamic doctors in science today. On the basis of the peculiarities of the thoughts of Islamic figures so that they can spur today's Islamic healers to reach their glorious era. The author also adds some ethics of Muslim doctors that can help us face moral challenges, especially those that are getting worse. Hopefully this book is useful for all of us. Amen
