. Europe especially has greatly benefitted from his works. Razi has a special, universal fame. One cannot find many scientists who have written as many useful books as Razi. Over 250 books have been authored by Razi, most of which are about medicine. The most important one is the book called Al-Hawi which we will discuss later. Another book is Al-Mansuri , or Mansuri Medicine, which has been compiled for Amir Ibn Mansur Ibn Ishaq Samani the ruler of Rey.

This book is divided into two sections and is briefer than Al- Hawi . In the Middle Ages, Al-Mansuri was translated into Latin and it has been reprinted numerous times since then. Other books by Razi are Borhan , Tibbun Nufus and a book called Quality of Sight , another book which is concerned with the diseases of the joints of the body and there is a book about avoiding extremes.

The Arab Jalinus Razi, has made a lot of objections and criticisms in the ideas of the famous physician Galenus in a book Al-Shakuk . The book called Man la Yahdharul Tayb is one of the famous works of Razi and Ibn Abi Usaybiah has called it the medicine of poor people; because in this book he has outlined simple and inexpensive instructions for treating patients which is very helpful for the deprived segment of society. In many of his instructions a doctor's advice is not needed[^1].

The book Bur'a Sa'a is anotherof Razi's works describing the treatment of emergency cases before reaching a doctor. In a book called Al Tibbul Muluki Razi proposed the treatment of all diseases with food, not medicine. This method of curing was a new method and since that time, has gained a lot of supporters. Other books by Razi are too numerous to mention individually.

In addition to books, there are many articles said to be written by Razi in the Middle Ages which were translated into Latin and, after the invention of the printing machine, were printed often[^2]. Al-Hawi- A Medical Encyclopedia The most important and the biggest work of Razi is a world famous book called Al-Hawi, which has been called the 'general book on the science of medicine'. This encyclopedia identified and discussed all or most of the problems facing medical science at that time.

The ideas and methods of treatment of the ancient Greeks, Iranians and other scientists have also been collected in this book.
