حي بن يقظان
Theologus Autodidactus ("The Self-taught Theologian"), originally titled The Treatise of Kāmil on the Prophet's Biography (), also known as Risālat Fādil ibn Nātiq ("The Book of Fādil ibn Nātiq"), is a theological novel written by Ibn al-Nafis. This work is one of the first Arabic novels, may be considered a prototypical science fiction novel, of which it contained numerous elements, 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.
