Šaraf al-Dīn ʿAlī Yazdī (who composed poetry under the penname “Šaraf”) was a reputable man of learning and composition during early to mid 9th/15th century Tīmūrid times. He was a favorite of both the Tīmūrid ruler Šāh Ruḫ (r. 807/1405 to 850/1447) and his son Mīrzā Abu al-Fath Ibrāhīm Sulṭān, who was the governor of Fars. Among Šaraf al-Dīn’s various works there is an anthology of Arabic and Persian poetry, a work on riddles, and a work on magic squares and lucky numbers. However, it is his work
Ẓafar-nāmah, completed in 828/1424-5, which has brought him the most fame.
