Question: What subject was studied in the birthplace of Ibn al-Tilmīdh?

full_context: Document 1: Madrasa: From around 750, during the Abbasid Caliphate, women “became renowned for their brains as well as their beauty”. In particular, many well known women of the time were trained from childhood in music, dancing and poetry. Mahbuba was one of these. Another feminine figure to be remembered for her achievements was Tawaddud, "a slave girl who was said to have been bought at great cost by Hārūn al-Rashīd because she had passed her examinations by the most eminent scholars in astronomy, medicine, law, philosophy, music, history, Arabic grammar, literature, theology and chess". Moreover, among the most prominent feminine figures was Shuhda who was known as "the Scholar" or "the Pride of Women" during the 12th century in Baghdad. Despite the recognition of women's aptitudes during the Abbasid dynasty, all these came to an end in Iraq with the sack of Baghdad in 1258.
Document 2: Milad Hospital: Milad Hospital is the largest specialized and subspecialized hospital in Iran. This hospital is a complementary health service provider in Iran's Social Security organization (SSO) chain of hospitals. Milad hospital currently employs more than 5600 specialists and subspecialists of various fields.
Document 3: History of science: From their beginnings in Sumer (now Iraq) around 3500 BC, the Mesopotamian people began to attempt to record some observations of the world with numerical data. But their observations and measurements were seemingly taken for purposes other than for elucidating scientific laws. A concrete instance of Pythagoras' law was recorded, as early as the 18th century BC: the Mesopotamian cuneiform tablet Plimpton 322 records a number of Pythagorean triplets (3,4,5) (5,12,13). ..., dated 1900 BC, possibly millennia before Pythagoras,  but an abstract formulation of the Pythagorean theorem was not.
Document 4: Ibn Jazla: Abu ali Yahya ibn Isa Ibn Jazla Al Baghdadi or Ibn Jazlah (Arabic,أبو يحيى ابن عيسى بن جزله), Latinized as Buhahylyha Bingezla, was an 11th-century Arab physician of Baghdad and author of an influential treatise on regimen that was translated into Latin in 1280 AD by the Sicilian Jewish physician Faraj ben Salem.
Document 5: History of science: In Babylonian astronomy, records of the motions of the stars, planets, and the moon are left on thousands of clay tablets created by scribes. Even today, astronomical periods identified by Mesopotamian proto-scientists are still widely used in Western calendars such as the solar year and the lunar month. Using these data they developed arithmetical methods to compute the changing length of daylight in the course of the year and to predict the appearances and disappearances of the Moon and planets and eclipses of the Sun and Moon. Only a few astronomers' names are known, such as that of Kidinnu, a Chaldean astronomer and mathematician. Kiddinu's value for the solar year is in use for today's calendars. Babylonian astronomy was "the first and highly successful attempt at giving a refined mathematical description of astronomical phenomena." According to the historian A. Aaboe, "all subsequent varieties of scientific astronomy, in the Hellenistic world, in India, in Islam, and in the West—if not indeed all subsequent endeavour in the exact sciences—depend upon Babylonian astronomy in decisive and fundamental ways."
Document 6: Ibn al-Tilmidh: Ibn al-Tilmidh worked at the ʻAḍudī hospital in Baghdad where he eventually became its chief physician as well as court physician to the caliph Al-Mustadi, and in charge of licensing physicians in Baghdad. He mastered the Arabic, Persian, Greek and Syriac languages.
Document 7: History of mathematics: Babylonian mathematics refers to any mathematics of the peoples of Mesopotamia (modern Iraq) from the days of the early Sumerians through the Hellenistic period almost to the dawn of Christianity. The majority of Babylonian mathematical work comes from two widely separated periods: The first few hundred years of the second millennium BC (Old Babylonian period), and the last few centuries of the first millennium BC (Seleucid period). It is named Babylonian mathematics due to the central role of Babylon as a place of study. Later under the Arab Empire, Mesopotamia, especially Baghdad, once again became an important center of study for Islamic mathematics.
Document 8: Mesopotamia: Mesopotamia is a historical region in West Asia situated within the Tigris -- Euphrates river system, in modern days roughly corresponding to most of Iraq plus Kuwait, the eastern parts of Syria, Southeastern Turkey, and regions along the Turkish -- Syrian and Iran -- Iraq borders.
Document 9: History of science: In mathematics, the Persian mathematician Muhammad ibn Musa al-Khwarizmi gave his name to the concept of the algorithm, while the term algebra is derived from al-jabr, the beginning of the title of one of his publications. What is now known as Arabic numerals originally came from India, but Muslim mathematicians did make several refinements to the number system, such as the introduction of decimal point notation. Sabian mathematician Al-Battani (850-929) contributed to astronomy and mathematics, while Persian scholar Al-Razi contributed to chemistry and medicine.
Document 10: Translation: The Arabs undertook large-scale efforts at translation. Having conquered the Greek world, they made Arabic versions of its philosophical and scientific works. During the Middle Ages, translations of some of these Arabic versions were made into Latin, chiefly at Córdoba in Spain. King Alfonso X el Sabio (Alphonse the Wise) of Castille in the 13th century promoted this effort by founding a Schola Traductorum (School of Translation) in Toledo. There Arabic texts, Hebrew texts, and Latin texts were translated into the other tongues by Muslim, Jewish and Christian scholars, who also argued the merits of their respective religions. Latin translations of Greek and original Arab works of scholarship and science helped advance European Scholasticism, and thus European science and culture.
Document 11: Father of surgery: The Arab physician Abu al - Qasim al - Zahrawi (936 - 1013) wrote Al - Tasrif (The Method of Medicine), a 30 - part medical encyclopedia in Arabic. In the encyclopedia, he introduced his collection of over 200 surgical instruments, many of which were never used before. Some of his works included being the first to describe and prove the hereditary pattern behind hemophilia, as well as describing ectopic pregnancy and stone babies. He has been called the ``father of surgery ''.
Document 12: Ibn Abi Usaibia: Ibn Abi Usaibia was born at Damascus, a member of the Banu Khazraj tribe. The son of a physician, he studied medicine at Damascus and Cairo. In 1236 he was appointed physician to a new hospital in Cairo, but the following year he took up an offer by ruler of Damascus, of a post in Salkhad, near Damascus, where he lived until his death. His only surviving work is "Lives of the Physicians". In that work he mentions another of his works, but it has not survived.
Document 13: Muslim world: The Islamic Golden Age coincided with the Middle Ages in the Muslim world, starting with the rise of Islam and establishment of the first Islamic state in 622. The end of the age is variously given as 1258 with the Mongolian Sack of Baghdad, or 1492 with the completion of the Christian Reconquista of the Emirate of Granada in Al-Andalus, Iberian Peninsula. During the reign of the Abbasid caliph Harun ar-Rashid (786 to 809), the legendary House of Wisdom was inaugurated in Baghdad where scholars from various parts of the world sought to translate and gather all the known world's knowledge into Arabic. The Abbasids were influenced by the Quranic injunctions and hadiths, such as "the ink of a scholar is more holy than the blood of a martyr," that stressed the value of knowledge. The major Islamic capital cities of Baghdad, Cairo, and Córdoba became the main intellectual centers for science, philosophy, medicine, and education. During this period, the Muslim world was a collection of cultures; they drew together and advanced the knowledge gained from the ancient Greek, Roman, Persian, Chinese, Indian, Egyptian, and Phoenician civilizations.
Document 14: Ancient Near East: The ancient Near East was the home of early civilizations within a region roughly corresponding to the modern Middle East: Mesopotamia (modern Iraq, southeast Turkey, southwest Iran, northeastern Syria and Kuwait), ancient Egypt, ancient Iran (Elam, Media, Parthia and Persia), Anatolia / Asia Minor and Armenian Highlands (Turkey's Eastern Anatolia Region, Armenia, northwestern Iran, southern Georgia, and western Azerbaijan), the Levant (modern Syria, Lebanon, Palestine, Israel, and Jordan), Cyprus and the Arabian Peninsula. The ancient Near East is studied in the fields of Near Eastern archaeology and ancient history.
Document 15: Madrasa: Al-Azhar University, founded in Cairo, Egypt in 975 by the Ismaʻīlī Shīʻī Fatimid dynasty as a jāmiʻah, had individual faculties for a theological seminary, Islamic law and jurisprudence, Arabic grammar, Islamic astronomy, early Islamic philosophy and logic in Islamic philosophy. The postgraduate doctorate in law was only obtained after "an oral examination to determine the originality of the candidate's theses", and to test the student's "ability to defend them against all objections, in disputations set up for the purpose." ‘Abd al-Laṭīf al-Baghdādī also delivered lectures on Islamic medicine at al-Azhar, while Maimonides delivered lectures on medicine and astronomy there during the time of Saladin. Another early jāmiʻah was the Niẓāmīyah of Baghdād (founded 1091), which has been called the "largest university of the Medieval world." Mustansiriya University, established by the ʻAbbāsid caliph al-Mustanṣir in 1233, in addition to teaching the religious subjects, offered courses dealing with philosophy, mathematics and the natural sciences.
