and practiced medicine for several years. One of his most notable students was the famous Christian physician Ibn al-Quff. Ibn al-Nafis also taught jurisprudence at al-Masruriyya Madrassa (Arabic: المدرسة المسرورية). His name is found among those of other scholars, which gives insight into how well he was regarded in the study and practice of religious law. Ibn al-Nafis lived most of his life in Egypt, and witnessed several pivotal events like the fall of Baghdad and the rise of Mamluks. He even became the personal physician of the sultan Baibars and other prominent political leaders, thus showcasing himself as an authority among practitioners of medicine. Later in his life, when he was 74 years old, Ibn al-Nafis was appointed as the chief physician of the newly founded al-Mansori hospital where he worked for the rest of his life. Ibn al-Nafis died in Cairo after some days of sickness. His student Safi Aboo al-fat'h composed a poem about him.

Ibn al-Nafis bequeathed his encyclopedia along with all of his library to the Mansoory hospital where he had worked before his death.

The Egyptian scholar Youssef Ziedan started a project of collecting and examining the extant manuscripts of this work that are cataloged in many libraries around the world, including the Cambridge University Library, the Bodleian Library, and the Lane Medical Library at Stanford University. Commentary on Anatomy in Ibn Sina's Canon Sharh Tashrih al-Qanun ("Commentary on Anatomy in Books I and II of Ibn Sina's Kitab al-Qanun"), published when Ibn al-Nafis was only 29 years old, still it is regarded by many as his most famous work.
