Muhammad bin Zakaria ar-Razi (Rhazes) was a doctor, as well as a chemist and philosophy. He has written two hundred titles on medicine. Among these are Al-Mansuri (translated as Liber Almamoris in the 15th century), which consists of 10 volumes. In addition, he also wrote Al-Judari al-Hasbah (smallpox and measles).

Apart from Ibn Sina (Avicenna), who was known as an early pioneer of medical science, Abu Bakar Muhammad bin Zakaria Ar Razi (better known as Ar-Razi) was also considered a pioneer of modern medicine. He got the title Gale (Greek surgeon).

Ar-Razi was born in Bandar ar-Rayy, north of Tehran, Iran, in 864 AD. And he died at 924 AD. Since childhood, he has shown great interest in science. He studied medicine after 30 years old.

Nevertheless, Ar Razi, who was educated and raised in a strict religious environment, was actually interested and seriously involved in medical problems precisely when he was old. It’s just that, although his seriousness towards this one scientific discipline has existed since young, Ar Razi’s expertise and genius in the field of medicine far exceeded his expertise in old age. This is what places him in a row of highly respected and respected Muslim scientists in the Western world.

Some historians say that Ar Razi has actually been involved in philosophy, chemistry, mathematics, and literature since he was young. Quoting the statement of a historian named Ibn Khallikan, as well as a Western biographer, A J. Aberry in the introduction to the book of Razi, The Spiritual Physic of Rhazes, “In his youth, Ar Razi liked to play harps and pursue vocal music . However, as he grew older, he abandoned his hobby while saying that music originating from the area between mustache and beard had no appeal and charm to be praised and admired. ”

Since then, several references mention that Ar-Razi focused more on the tradition of intellectualism in the fields of philosophy, logic, exact sciences, and medicine.

In this field of medicine, he really concentrated and was seriously involved in this field. In fact, he was willing to spend time going to Baghdad, Iraq, to ​​deepen medical science. At that time, Baghdad was at the golden peak of intellectualism.

In the city of Baghdad, Al-Razi studied with the Huma¬yun Ibn Ishaq, a scholar who mastered medicine well. From this teacher who has been practicing for a long time in the field of medicine, Al Razi mastered the basics of medical treatment well.

Upon his return from Baghdad, Al-Razi decided to dedicate himself to the community, especially in the field of medicine which he had been engaged in. In a short time, due to his perseverance, he received special attention from the local authorities.

Thanks to that reputation and strength, the government decided to give a mandate to him to lead a hospital in Tehran. In addition to being a doctor, this figure also known as humility also optimizes his service by teaching.

In the midst of his seriousness in pursuing medical science, the older Razi attacked cataracts and made his eyes blind. His eyesight practically does not work. When he was advised to hold a record, it was said that Ar Razi replied, “No, I have seen this whole world for so long that I am tired of it.”

Ar-Razi’s dedication and genius has been recognized by the Western world. Many Western scientists call it the greatest pioneer of the Islamic world in the field of medicine.

“The Razhes (Ar Razi) is the greatest physician (doctor) in the Islamic world, and one of the largest in history,” said Max Mayerhof.

Meanwhile, a well-known Western historian, George Sarton, commented on Ar Razi intelligently. He said, “Razi who came from Persia was not only the greatest physician in the world of Islam and the Middle Ages. He also acts as a chemist and physicist. He can be stated as one of the pioneers of latrochemistry during the Renaissance. He is indeed great in theory. He succeeded in combining his vast knowledge through Hippocratic wisdom. ”

Thanks to the services of Al-Razi, it is appropriate for us to feel indebted to him and we must thank this figure.
