Ala-al-Din Abu al-Hasan Ali Ibn Abi al-Hazm al-Qarshi al-Damashqi al-Misri was born in 607 A.H. of Damascus. He was educated at the Medical College-cum-Hospital founded by Nur al-Din Zangi. In medicine his teacher was Muhazzab al-Din Abd al-Rahim. Apart from medicine, Ibn al-Nafis learnt jurisprudence, literature and theology. He thus became a renowned expert on Shafi'i School of Jurisprudence as well as a reputed physician.

After acquiring his expertise in medicine and jurisprudence, he moved to Cairo where he was appointed as the Principal at the famous Nasri Hospital. Here he imparted training to a large number of medical specialists, including Ibn al-Quff al-Masihi, the famous surgeon. He also served at the Mansuriya School at Cairo. When he died in 678 A. H. he donated his house, library and clinic to the Mansuriya Hospital.

His major contribution lies in medicine. His approach comprised writing detailed commentaries on early works, critically evaluating them and adding his own original contribution. His major original contribution of great significance was his discovery of the blood's circulatory system, which was re-discovered by modern science after a lapse of three centuries. He was the first to correctly describe the constitution of the lungs and gave a description of the bronchi and the interaction between the human body's vessels for air and blood. Also, he elaborated the function of the coronary arteries as feeding the cardiac muscle.

The most voluminous of his books is Al-Shamil fi al-Tibb, which was designed to be an encyclopedia comprising 300 volumes, but it could not be completed due to his death. The manuscript is available at Damascus. His book on ophthalmology is largely an original contribution and is also extant. However, his book that became most famous was Mujaz al-Qanun and a number of commentaries were written on this. His own commentaries include one on Hippocrates' book. He wrote several volumes on Ibn Sina's Qanun, that are still extant. Likewise he wrote a commentary on Hunayn Ibn Ishaq's book. Another famous book embodying his original contribution was on the effects of diet on health, entitled Kitab al-Mukhtar fi al-Aghdhiya.

Ibn Al-Nafis' works integrated the then existing medical knowledge and enriched it, thus exerting great influence on the development of medical science, both in the East and the West. However, only one of his books was translated into Latin at early stages and, therefore, a part of his work remained unknown to Europe for a long time.

Abd al-Rahman Ibn Mohammad is generally known as Ibn Khaldun after a remote ancestor. His parents, originally Yemenite Arabs, had settled in Spain, but after the fall of Seville, had migrated to Tunisia. He was born in Tunisia in 1332 A.D., where he received his early education and where, still in his teens, he entered the service of the Egyptian ruler Sultan Barquq. His thirst for advanced know- ledge and a better academic setting soon made him leave this service and migrate to Fez. This was followed by a long period of unrest marked by contemporary political rivalries affecting his career. This turbulent period also included a three year refuge in a small village Qalat Ibn Salama in Algeria, which provided him with the opportunity to write Muqaddimah, the first volume of his world history that won him an immortal place among historians, sociologists and philosophers. The uncertainty of his career still continued, with Egypt becoming his final abode where he spent his last 24 years. Here he lived a life of fame and respect, marked by his appointment as the Chief Malakite Judge and lecturing at the AL-Azhar University, but envy caused his removal from his high judicial office as many as five times.

Ibn Khaldun's chief contribution lies in philosophy of history and sociology. He sought to write a world history preambled by a first volume aimed at an analysis of historical events. This volume, commonly known as Muqaddimah or 'Prolegomena', was based on Ibn Khaldun's unique approach and original contribution and became a masterpiece in literature on philosophy of history and sociology. The chief concern of this monumental work was to identify psychological, economic, environmental and social facts that contribute to the advancement of human civilization and the currents of history. In this context, he analyzed the dynamics of group relationships and showed how group-feelings, al-'Asabiyya, give rise to the ascent of a new civilization and political power and how, later on, its diffusion into a more general civilization invites the advent of a still new 'Asabiyya in its pristine form. He identified an almost rhythmic repetition of rise and fall in human civilization, and analyzed factors contributing to it. His contribution to history is marked by the fact that, unlike most earlier writers interpreting history largely in a political context, he emphasized environmental, sociological, psychological and economic factors governing the apparent events. This revolutionized the science of history and also laid the foundation of Umraniyat (Sociology).

Apart from the Muqaddimah that became an important independent book even during the lifetime of the author, the other volumes of his world history Kitab al-I'bar deal with the history of Arabs, contemporary Muslim rulers, contemporary European rulers, ancient history of Arabs, Jews, Greeks, Romans, Persians, etc., Islamic History, Egyptian history and North-African history, especially that of Berbers and tribes living in the adjoining areas. The last volume deals largely with the events of his own life and is known as Al-Tasrif. This was also written in a scientific manner and initiated a new analytical tradition in the art of writing autobiography A book on mathematics written by him is not extant.

Ibn Khaldun's influence on the subject of history, philosophy of history, sociology, political science and education has remained paramount ever since his life. His books have been translated into many languages, both in the East and the West, and have inspired subsequent development of these sciences. For instance, Prof. Gum Ploughs and Kolosio consider Muqaddimah as superior in scholarship to Machiavelli's The Prince written a century later, as the former bases the diagnosis more on cultural, sociological, economic and psychological factors.

Abu'l Waleed Muhammad Ibn Ahmad Ibn Muhammad Ibn Rushd, known as Averroes in the West, was born in 1128 A.D. in Cordova, where his father and grandfather had both been judges. His grandfather was well versed in Fiqh (MaIiki School) and was also the Imam of the Jamia Mosque of Cordova. The young Ibn Rushd received his education in Cordova and lived a quiet life, devoting most of his time to learned pursuits. He studied philosophy and law from Abu J'afar Haroon and from Ibn Baja; he also studied medicine.

Al-Hakam, the famous Umayyad Caliph of Spain, had constructed a magnificent library in Cordova, which housed 500,000 books. He himself had studied many of these and made brief marginal comments on them. This rich collection laid the foundation for intellectual study in Spain and provided the background for men like Ibn Rushd, who lived 2 centuries later.

Abu Yaqub, the Caliph of Morocco, called him to his capital and appointed him as his physician in place of Ibn Tufail. His son Yaqub al-Mansur retained him for some time but soon Ibn Rushd's views on theology and philosophy drew the Caliph's wrath. All his books, barring strictly scientific ones, were burnt and he was banished to Lucena. However, as a result of intervention of several leading scholars he was forgiven after about four years and recalled to Morocco in 1198; but he died towards the end of the same year. Ibn Rushd made remarkable contributions in philosophy, logic, medicine, music and jurisprudence. In medicine his well-known book Kitab al-Kulyat fi al-Tibb was written before 1162 A.D. Its Latin translation was known as 'Colliget'. In it, Ibn Rushd has thrown light on various aspects of medicine, including the diagnoses, cure and prevention of diseases. The book concentrates on specific areas in comparison of Ibn Sina's wider scope of at-Qanun, but contains several original observations of Ibn Rushd.

In philosophy, his most important work Tuhafut al-Tuhafut was written in response to al-Ghazali's work. Ibn Rushd was criticized by many Muslim scholars for this book, which, nevertheless, had a profound influence on European thought, at least until the beginning of modern philosophy and experimental science. His views on fate were that man is neither in full control of his destiny nor is it fully predetermined for him. He wrote three commentaries on the works of Aristotle, as these were known then through Arabic translations. The shortest Jami may be considered as a summary of the subject. The intermediate was Talkhis and the longest was the Tafsir. These three commentaries would seem to correspond to different stages in the education of pupils; the short one was meant for the beginners, then the intermediate for the students familiar with the subject, and finally the longest one for advanced studies. The longest commentary was, in fact, an original contribution as it was largely based on his analysis including interpretation of Qu'ranic concepts.

In the field of music, Ibn Rushd wrote a commentary on Aristotle's book De Anima. This book was translated into Latin by Mitchell the Scott.

In astronomy he wrote a treatise on the motion of the sphere, Kitab fi-Harakat al-Falak. He also summarized Almagest and divided it into two parts: description of the spheres, and movement of the spheres. This summary of the Almagest was translated from Arabic into Hebrew by Jacob Anatoli in 1231.

According to Ibn al-Abbar, Ibn Rushd's writings spread over 20,000 pages, the most famous of which deal with philosophy, medicine and jurisprudence. On medicine alone he wrote 20 books. Regarding jurisprudence, his book Bidayat al-Mujtahid wa-Nihayat-al-Muqtasid has been held by Ibn Jafar Zahabi as possibly the best book on the Maliki School of Fiqh. Ibn Rushd's writings were translated into various languages, including Latin, English, German and Hebrew. Most of his commentaries on philosophy are preserved in the Hebrew translations, or in Latin translations from the Hebrew, and a few in the original Arabic, generally in Hebrew script. This reveals his wider acceptance in the West in comparison to the East. The commentary on zoology is entirely lost. Ibn Rushd also wrote commentaries on Plato's Republic, Galen's treatise on fevers, al-Farabi's logic, etc. Eighty-seven of his books are still extant.

Ibn Rushd has been held as one of the greatest thinkers and scientists of the l2th century. According to Philip Hitti, Ibn Rushd influenced Western thought from the l2th to the l6th centuries. His books were included in the syllabi of Paris and other universities till the advent of modern experimental sciences.
