The metaphor of a golden age began to be applied in 19th-century literature about Islamic history, in the context of the western aesthetic fashion known as Orientalism. There is no unambiguous definition of term, and depending on whether it is used with a focus on cultural or on military achievement, it may be taken to refer to rather disparate time spans. During the early 20th century, the term was used only occasionally, and often referred to the early military successes of the Rashidun caliphs. The various Quranic injunctions and Hadith, which place values on education and emphasize the importance of acquiring knowledge, played a vital role in influencing the Muslims of this age in their search for knowledge and the development of the body of science.

The Islamic Empire heavily patronized scholars. The money spent on the Translation Movement for some translations is estimated to be equivalent to about twice the annual research budget of the United Kingdom’s Medical Research Council. During this period, the Muslims showed a strong interest in assimilating the scientific knowledge of the civilizations that had been conquered. Throughout the 4th to 7th centuries, Christian scholarly work in the Greek and Syriac languages was either newly translated or had been preserved since the Hellenistic period.

A manuscript written on paper during the Abbasid Era. With a new and easier writing system, and the introduction of paper, information was democratized to the extent that, for probably the first time in history, it became possible to make a living from simply writing and selling books. Among the various countries and cultures conquered through successive Islamic conquests, a remarkable number of scientists originated from Persia, who contributed immensely to the scientific flourishing of the Islamic Golden Age. Culturally, politically, and most remarkable of all even religiously, the Persian contribution to this new Islamic civilization is of immense importance. The work of Iranians can be seen in every field of cultural endeavor, including Arabic poetry, to which poets of Iranian origin composing their poems in Arabic made a very significant contribution. Science, medicine, philosophy and technogy in the newly Islamized Iranian society was influenced by and based on the scientific model of the major pre-Islamic Iranian universities in the Sassanian Empire. The centrality of scripture and its study in the Islamic tradition helped to make education a central pillar of the religion in virtually all times and places in the history of Islam.

The importance of learning in the Islamic tradition is reflected in a number of hadiths attributed to Muhammad, including one that instructs the faithful to “seek knowledge, even in China”. Education would begin at a young age with study of Arabic and the Quran, either at home or in a primary school, which was often attached to a mosque. For the first few centuries of Islam, educational settings were entirely informal, but beginning in the 11th and 12th centuries, the ruling elites began to establish institutions of higher religious learning known as madrasas in an effort to secure support and cooperation of the ulema. Muslims distinguished disciplines inherited from pre-Islamic civilizations, such as philosophy and medicine, which they called “sciences of the ancients” or “rational sciences”, from Islamic religious sciences. Sciences of the former type flourished for several centuries, and their transmission formed part of the educational framework in classical and medieval Islam. The University of Al Karaouine, founded in 859 AD, is arguably the world’s oldest degree-granting university.

The Al-Azhar University was another early university. Juristic thought gradually developed in study circles, where independent scholars met to learn from a local master and discuss religious topics. The classical theory of Islamic jurisprudence elaborates how scriptures should be interpreted from the standpoint of linguistics and rhetoric. Avicenna argued his “Floating man” thought experiment concerning self-awareness, in which a man prevented of sense experience by being blindfolded and free falling would still be aware of his existence. In epistemology, Ibn Tufail wrote the novel Hayy ibn Yaqdhan and in response Ibn al-Nafis wrote the novel Theologus Autodidactus. Muḥammad ibn Mūsā al-Khwārizmī played a significant role in the development of algebra, arithmetic and Hindu-Arabic numerals.

Islamic art makes use of geometric patterns and symmetries in many of its art forms, notably in girih tilings. A triangle labelled with the components of the law of sines. The Book of Unknown Arcs of a Sphere in the 11th century. Alhazen discovered the sum formula for the fourth power, using a method that could be generally used to determine the sum for any integral power. He used this to find the volume of a paraboloid. He could find the integral formula for any polynomial without having developed a general formula.

Avicenna made rules for testing the effectiveness of drugs, including that the effect produced by the experimental drug should be seen constantly or after many repetitions, to be counted. Alhazen played a role in the development of optics. Al-Kindi warned against alchemists attempting the transmutation of simple, base metals into precious ones like gold in the ninth century. The eye, according to Hunain ibn Ishaq. From a manuscript dated circa 1200. In the nervous system, Rhazes stated that nerves had motor or sensory functions, describing 7 cranial and 31 spinal cord nerves. Modern commentators have likened medieval accounts of the “struggle for existence” in the animal kingdom to the framework of the theory of evolution.

The Banū Mūsā brothers, in their Book of Ingenious Devices, describe an automatic flute player which may have been the first programmable machine. You can help by adding to it. Entrance to the Qawaloon complex which housed the notable Qawaloon hospital in Cairo. The earliest known Islamic hospital was built in 805 in Baghdad by order of Harun Al-Rashid, and the most important of Baghdad’s hospitals was established in 982 by the Buyid ruler ‘Adud al-Dawla. The typical hospital was divided into departments such as systemic diseases, surgery, and orthopedics, with larger hospitals having more diverse specialties. Systemic diseases” was the rough equivalent of today’s internal medicine and was further divided into sections such as fever, infections and digestive issues.

Every department had an officer-in-charge, a presiding officer and a supervising specialist. For less serious cases, physicians staffed outpatient clinics. Cities also had first aid centers staffed by physicians for emergencies that were often located in busy public places, such as big gatherings for Friday prayers. The region also had mobile units staffed by doctors and pharmacists who were supposed to meet the need of remote communities. Medical students would accompany physicians and participate in patient care. Hospitals in this era were the first to require medical diplomas to license doctors. The licensing test was administered by the region’s government appointed chief medical officer.

Hospitals were forbidden by law to turn away patients who were unable to pay. Eventually, charitable foundations called waqfs were formed to support hospitals, as well as schools. The hospital shall keep all patients, men and women, until they are completely recovered. All costs are to be borne by the hospital whether the people come from afar or near, whether they are residents or foreigners, strong or weak, low or high, rich or poor, employed or unemployed, blind or sighted, physically or mentally ill, learned or illiterate. There are no conditions of consideration and payment, none is objected to or even indirectly hinted at for non-payment. By the ninth century, there was a rapid expansion of private pharmacies in many Muslim cities. Initially, these were unregulated and managed by personnel of inconsistent quality.
