Title: Ibn Sahl (mathematician)
Content:  Ibn Sahl (full name Abū Saʿd al-ʿAlāʾ ibn Sahl أبو سعد العلاء ابن سهل; c. 940–1000) was a Persian    mathematician and physicist of the Islamic Golden Age, associated with the Buyid court of Baghdad. Nothing in his name allows us to glimpse his country of origin. He is known to have written an optical treatise around 984. The text of this treatise was reconstructed by Roshdi Rashed from two manuscripts (edited 1993).: Damascus, al-Ẓāhirīya MS 4871, 3 fols., and Tehran, Millī MS 867, 51 fols. The Tehran manuscript is much longer, but it is badly damaged, and the Damascus ms. contains a section missing entirely from the Tehran ms.The Damascus ms. has the title Fī al-'āla al-muḥriqa "On the burning instruments", the Tehran

Consequently, Ulugh Beg gathered many great mathematicians and scientists of the Middle East. In 1414, al-Kashi took this opportunity to contribute vast amounts of knowledge to his people. His best work was done in the court of Ulugh Beg. Al-Kashi was still working on his book, called “Risala al-watar wa’l-jaib” meaning “The Treatise on the Chord and Sine”, when he died, probably in 1429. Some scholars believe that Ulugh Beg may have ordered his murder, because he went against Islamic theologians.

Ragep, a historian of science in Islam, estimated in 2019 that "tens of thousands" of Arabic manuscripts in mathematical sciences and philosophy remain unread, which give studies which "reflect individual biases and a limited focus on a relatively few texts and scholars". 
Title: Ibn al‐Ha'im al‐Ishbili
Content:  Abu Muhammad Abd al-Haqq al‐Ghafiqi al‐Ishbili (Arabic: ابن الهائم), known as Ibn al‐Hāʾim (fl. c. 1213) was a medieval Muslim astronomer and mathematician from Seville in Al-Andalus. He began his studies as a mathematician and studied the works of Al-Jayyani and Jabir ibn Aflah. He was the author of the al‐Zīj al‐kāmil fī al‐talim (The perfect handbook on mathematical astronomy; which had seven chapters). He gives historical data on the life and works of Al-Zarqali and the creation of the Tables of Toledo by astronomers in Toledo patronized by Said Al-Andalusi. He further extends Al-Zarqali's theories on the oscillation of the obliquity of the ecliptic, also presents the spherical trigonometrical formulae, gives a longitude of the solar apogee of 85° 49′ and further confirmed the works of Al-Zarqali. His work seems exceptional in Western Islam, as very complete and accurate, and had a great influence on the development of astronomy in the Maghreb.

What is unknown is how Banū Mūsā and Thābit occupied himself with mathematics, astronomy, astrology, magic, mechanics, medicine, and philosophy. Later in his life, Thābit's patron was the Abbasid Caliph al-Mu'tadid (reigned 892&ndash;902), whom he became a court astronomer for. Thābit became the Caliph's personal friend and courtier. Thābit died in Baghdad in 901. His son, Sinan ibn Thabit and grandson, Ibrahim ibn Sinan would also make contributions to the medicine and science. By the end of his life, Thābit had managed to write 150 works on mathematics, astronomy, and medicine. With all the work done by Thābit, most of his work has not lasted time. There are less than a dozen work by him that has survived.

His three principal surviving works are mathematical: Al-Badi' fi'l-hisab (Wonderful on calculation), Al-Fakhri fi'l-jabr wa'l-muqabala (Glorious on algebra), and Al-Kafi fi'l-hisab (Sufficient on calculation).
Title: Islamic Golden Age
Content:  Economic historian Joel Mokyr has argued that Islamic philosopher al-Ghazali (1058–1111) "was a key figure in the decline in Islamic science", as his works contributed to rising mysticism and occasionalism in the Islamic world. Against this view, Saliba (2007) has given a number of examples especially of astronomical research flourishing after the time of al-Ghazali.
Title: 'Abd al-Hamīd ibn Turk
Content:  ʿAbd al-Hamīd ibn Turk (fl. 830), known also as ʿAbd al-Hamīd ibn Wase ibn Turk Jili (ابومحمد عبدالحمید بن واسع بن ترک الجیلی) was a ninth-century Muslim mathematician. Not much is known about his life. The two records of him, one by Ibn Nadim and the other by al-Qifti are not identical. Al-Qifi mentions his name as ʿAbd al-Hamīd ibn Wase ibn Turk al-Jili. Jili means from Gilan. On the other hand, Ibn Nadim mentions his nisbah as khuttali (ختلی), which is a region located north of the Oxus and west of Badakhshan. In one of the two remaining manuscripts of his al-jabr wa al-muqabila, the recording of his nisbah is closer to al-Jili. David Pingree / Encyclopaedia Iranica states that he originally hailed from Khuttal or Gilan. He wrote a
