According to Ibn Khaldun's sources, he claimed to have received a new revelation from God, with 80 chapters, some called after prophets, such as Adam, Noah, and others after other things, such as the Duck, the Camel, the Elephant, Harut and Marut, Iblis and "Chapter of the Wonders of the World"; they read these chapters in their prayers. He established laws for his people, and was called by them "Ṣāliḥ al-Mu'minin" (Restorer of the Believers.) This claimed revelation was written in the Berber language, and called a Qur'an.
