He served as the chief physician at the hospitals in Ray and Baghdad, where he implemented advanced medical practices.

He emphasized the importance of careful observation and documentation of patient’s symptoms and treatment outcomes, laying the groundwork for clinical case studies [7] .

His philosophical writings often challenged established religious and philosophical doctrines, promoting a more secular and scientific approach to understanding the world.

In Chemistry, Al-Razi made significant advancements in the field of alchemy, which later evolved into modern chemistry. He is credited with the discovery of several chemical substances and processes, including the distillation of alcohol. He improved laboratory equipment and techniques, such as the use of the alembic for distillation and the development of chemical substances like sulfuric acid.

Among his works in the field is “Kitab al-Asrar” (The Book of Secrets) which outlines various chemical processes and experiments, including methods for the preparation of chemical substances and the refinement of metals [11] .
