After describing his illness...

After describing his illness, George agreed to begin treating him and after sometime Mansur was cured. The Caliph became so interested in him that he did not want the doctor to return to Jondi Shapur and asked him to stay in Baghdad.George remained there and she was fluent in Arabic, Syriac and Persian, he wrote several books on medicine while in Baghdad, some of which he translated from Greek into Arabic.

The Research Period After spending some time translating new books and taking selected information from the non-Islamic sciences, the Muslims entered a new era of research. They displayed such initiative in the history of science that they were regarded with amazement. In medicine, in particular, they produced great physicians. Ibn -Abi -Usaybiah in one of the volumes of his book Tabaghatul Atba' (the classification of physicians) catagorized and listed the names of all of the Islamic scientists.

A Distinguished Scientist And Doctor In Islam One of the most famous examples of a Muslim scientist was Muhammad Ibn Zakariyya Razi, who was also nicknamed Tabib-al-Muslimin , (The Doctor of the Muslims) or Jalinusul Arab, (The Galenus of Arab). Razi was a respected physician, a famous philosopher and a very skilled mathematician, but he was best known in the field of medicine.

It is said that he was first a jeweller, but he had a great interest in chemistry and for that reason, he spent most of his time experimenting with various chemicals. Due to his hard working and daily contacts with various gases and chemicals his eyes began to be seriously inflamed. Razi consulted a doctor for treatment and was charged 500 Ashrafi, which was the unit of currency at that time. The doctor told him that "It was the money which was the real alchemy" and not what he was doing.

The doctor's words affected Razi so much that he began thinking of studying medicine at the age of 40. Razi's thought was materialised and at the age of forty he displayed such dedication to medicine and became such a good physician that anyone suffering from a physical ailment and had heard of Razi came to him.

In the years 289-295A.H,Razi was head of the physicians in Baghdad and for showing his greatness and the services he had rendered in medicine,experts in the history of science have said that' “The science of medicine which was in danger of dying, was revived by Jalinus, and it was Muhammad Ibn Zakariyya Razi who organized it.” This science was imperfect, but Ibn Sina perfected it.
