Abdallah ibn Faḍlallah Sharaf al-Din Shīrāzī (Persian: عبدالله ابن فضلالله شرفالدین شیرازی; fl.
[1][2] A native of Shiraz, Wassaf was a tax administrator in Fars during the reigns of Ghazan Mahmud and Öljaitü.
[3] He is the author of the historical work Tārīkḣ-i Waṣṣāf, also known as Tajziyat al-amṣār wa-tazjiyat al-a'ṣār (The allocation of cities and the propulsion of epochs).
His history, Tajziyat al-amṣār wa-tazjiyat al-a'ṣār (The allocation of cities and the propulsion of epochs)[4] also called Tārīkḣ-i Waṣṣāf,[5] was conceived as a continuation of Juwayni's Tārīkḣ-i Jahāngushāy[6][7] whose account of the rise of the Mongol Empire ended in 1257.
[6][8] Wassaf's florid style of prose is not easily followed by modern readers, and an abridged version entitled the Taḥrīr-i Tārīkḣ-i Waṣṣāf (1346/1967) has been edited by ʿAbd al-Muḥammad Āyatī.
