What do Ibn al-Shatir and Ibn Tufail have in common?
Ibn Tufail 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-Jawzi ʿAbd al-Raḥmān b. ʿAlī b. Muḥammad Abu ’l-Faras̲h̲ b. al-Jawzī (1126 – 14 June 1200), often referred to as Ibn al-Jawzī (Arabic: ابن الجوزي, "Ibn al-Jawzī"; 1126 – 14 June 1200) for short, or reverentially as Imam Ibn al-Jawzī by Sunni Muslims, was an Arab Muslim jurisconsult, preacher, orator, heresiographer, traditionist, historian, judge, hagiographer, and philologist who played an instrumental role in propagating the Hanbali school of orthodox Sunni jurisprudence in his native Baghdad during the twelfth-century. During "a life of great intellectual, religious and political activity," Ibn al-Jawzi came to be widely admired by his fellow Hanbalis for the tireless role he played in ensuring that that particular school – historically, the smallest of the four principal Sunni schools of law – enjoy the same level of "prestige" often bestowed by rulers on the Maliki, Shafi'i, and Hanafi rites.
