Question: What do Ibn al-Shatir and Ibn Tufail have in common?
Context: Ibn Tufail (c. 1105 – 1185) (full Arabic name: أبو بكر محمد بن عبد الملك بن محمد بن طفيل القيسي الأندلسي "Abu Bakr Muhammad ibn Abd al-Malik ibn Muhammad ibn Tufail al-Qaisi al-Andalusi"; Latinized form: "Abubacer Aben Tofail"; Anglicized form: "Abubekar" or "Abu Jaafar Ebn Tophail") was a Moorish Andalusian Muslim polymath: a writer, novelist, Islamic philosopher, Islamic theologian, physician, astronomer, vizier, and court official. Ibn al-Shatir or Ibn ash-Shatir (Arabic: ابن الشاطر‎ ‎ ; 1304–1375) was an Arab astronomer.  He worked as "muwaqqit" (موقت, religious timekeeper) in the Umayyad Mosque in Damascus and constructed a sundial for its minaret in 1371/72. Ibn Zuhr (Arabic: ‎ ‎ ; 1094–1162), traditionally known by his Latinized name of Avenzoar, was a Muslim Arab physician and surgeon and poet.  He was born at Seville in medieval Andalusia (present-day Spain), was a contemporary of Averroes and Ibn Tufail, and was the most well-regarded physician of his era.  He was particularly known for his emphasis on a more rational, empiric basis of medicine.  His major work, "Al-Taysīr fil-Mudāwāt wal-Tadbīr" ("Book of Simplification Concerning Therapeutics and Diet"), was translated into Latin and Hebrew and was influential to the progress of surgery.  He also improved surgical and medical knowledge by keying out several diseases and their treatments. Murrah ibn Ka'b (Arabic: مرة بن كعب‎ ‎ ) ibn Luay ibn Ghalib ibn Fihr ibn Malik was a man from Quraish tribe, supposed to have lived in the 4th century.  He was the sixth-in-line of Muhammad’s grandfathers.  He is the common ancestor of Muhammad’s all four grandparents.  He is also the common ancestor of six of Muhammad’s eight great-grandparents. Ḥayy ibn Yaqẓān (Arabic: حي بن يقظان‎ ‎ ""Alive, son of Awake""; Latin: "Philosophus Autodidactus" ""The Self-Taught Philosopher""; English: The Improvement of Human Reason: Exhibited in the Life of Hai Ebn Yokdhan ), the first Arabic novel, was written by Ibn Tufail (also known as "Aben Tofail" or "Ebn Tophail"), a Arab philosopher and physician, in early 12th century Islamic Spain.  The novel was itself named after an earlier Arabic allegorical tale and philosophical romance of the same name, written by Avicenna (Ibn Sina) in the early 11th century, though they had different stories. Theologus Autodidactus ("The Self-taught Theologian"), originally titled The Treatise of Kāmil on the Prophet's Biography (Arabic: الرسالة الكاملية في السيرة النبوية‎ ‎ ), also known as Risālat Fādil ibn Nātiq ("The Book of Fādil ibn Nātiq"), was the first theological novel, written by Ibn al-Nafis.  This work is one of the first Arabic novels, may be considered an early example of a science fiction novel, and an early example of a coming of age tale and a desert island story.  This novel was written sometime between 1268 and 1277.  It was partly a response to the philosophical novel "Hayy ibn Yaqdhan" by Andalusi writer Ibn Tufail. The Ring of the Dove (Arabic: طوق الحمامة, "Ṭawq al-Ḥamāmah") is a treatise on love written ca. 1022 by Ibn Hazm.  Normally a writer of theology and law, Hazm produced his only work of literature with "The Ring and the Dove".  Ibn Hazm borrowed heavily from Plato's Phaedrus, though the bulk of the work was still his own writing, rather than an anthology of other works.  Although the human aspects of affection are the primary concern, the book was still written from the perspective of a devout Muslim, and as such chastity and restraint were common themes. Abu Bakr ‘Aasim Ibn Abi al-Najud al-'Asadi (died 127AH/745CE), commonly known as ‘Aasim ibn Abi an-Najud, was one of the seven primary transmitters of the Qira'at, or variant readings of the Qur'an.  Of Persian origin, his method of reciting the Qur'an as transmitted by Hafs is the most common and popular way of reciting the holy book in the Muslim world in general. Al-Mursi Abu'l-'Abbas (1219 in Murcia – 1287 CE) (Arabic: المرسي أبو العباس‎ ‎ ) is a Sufi saint from Al-Andalus who later in his life moved to Alexandria in Egypt.  His complete name is Shahab al-Din Abu'l-'Abbas Ahmad ibn 'Umar ibn Mohammad al-Ansari al-Mursi.  Al-Mursi Abul-'Abbas, as he is now commonly called, is one of the four master saints of Egypt, the other three being Ahmad al-Badawi, al-Dessouqi and al-Haggag.  His legacy and reverence in Egypt were such that Mursi became a common name in the country. Yūsuf ibn Yaʿqūb ibn Is-ḥāq ibn Ibrāhīm (Arabic: يُـوسـف ابـن يَـعـقـوب ابـن إِسـحـاق ابـن إِبـراهـيـم‎ ‎ ) is a "Nabi" (Arabic: نَـبِي‎ ‎ , Prophet) mentioned in the Qurʾān, the scripture of Islam, and corresponds to Joseph (son of Jacob), a character from the Tanakh, the Jewish religious scripture, and the Christian Bible, who was estimated to have lived in the 16th century BCE.  It is one of the common names in the Middle East and among Muslim nations.  Of all of Jacob's children, Joseph was the one given the gift of prophecy.  Although the narratives of other prophets are mentioned in various "Surahs", the complete narrative of Joseph is given only in one Surah, Yusuf, making it unique.  It is said to be the most detailed narrative in the Qur'an and bears more details than the Biblical counterpart.
