This article is devoted to Kamāl al-Dīn al-Fārisī’s (d. 1319) additions to the well-known al-Abharī’s “proof” of the parallel postulate. These additions are found in only one codex, the manuscript Tunis 16167/7 also often referred to as one of the units of Tunis, al-Aḥmadiyya 5482 which is usually wrongly attributed to Qāḍī Zāde al-Rūmī.
