Abdallah ibn Faá¸Âlallah Sharaf al-Din ShërÃÂzë (; 1265âÂÂ1328), called Wassaf or Vassaf, was a Persian historian of the Ilkhanate. WaṣṣÃÂf, sometimes lengthened to WaṣṣÃÂf al-Ḥaá¸Ârat or Vassaf-e Hazrat (), is a title meaning "court panegyrist".
A native of Shiraz, Wassaf was a tax administrator in Fars during the reigns of Ghazan Mahmud and ÃÂljaitü. He is the author of the historical work TÃÂrëkḣ-i WaṣṣÃÂf, also known as Tajziyat al-amá¹£ÃÂr wa-tazjiyat al-a'á¹£ÃÂr (The allocation of cities and the propulsion of epochs).
His history, Tajziyat al-amá¹£ÃÂr wa-tazjiyat al-a'á¹£ÃÂr (The allocation of cities and the propulsion of epochs) also called TÃÂrëkḣ-i WaṣṣÃÂf, was conceived as a continuation of Juwayni's TÃÂrëkḣ-i JahÃÂngushÃÂy whose account of the rise of the Mongol Empire ended in 1257.
TÃÂrëkḣ-i WaṣṣÃÂf consisted of an introduction and five volumes. The first volume (first part) only was edited and translated by Joseph von Hammer-Purgstall, published 1855.
Wassaf's florid style of prose is not easily followed by modern readers, and an abridged version entitled the Taḥrër-i TÃÂrëkḣ-i WaṣṣÃÂf (1346/1967) has been edited by ÿAbd al-Muḥammad ÃÂyatë.
