From autobiographical references it is known that ʿAlīšāh journeyed to Samarqand with his father, a merchant, and returned to Bokhara at the age of thirty-six in 659/1260-61; after the sack of Bokhara by Abāqā’s army in 671/1272-73, he retired to Iraq but was not able to leave Baghdad till 690/1291. He wrote the following works, all in Persian: Ašǰār o aṯmār (Trees and fruits), an astrological work in five sections dedicated to the vizier Šams-al-dīn Moḥammad b. Sayf-al-dīn Aḥmadšāh b. Badr-al-dīn Mobārakšāh and composed fifteen years after the sack of Bokhara. The Ašǰār o aṯmār was published in Lucknow in 1903 with the title Ṯamara-ye šaǰara-ye noǰūm (Storey) or Aṯmār al-šaǰar (Mošār, Fehrest, col. 112). Aḥkām al-aʿwām (Judgments of years) in two treatises, composed in or shortly after 1291. Al-ʿOmdat al-Īlḵānīya (The Il-khanid principle), also called the Zīǰ-e šāhī, an abridgment of the Zīǰ-e Īlḵānī, which was completed by Naṣīr-al-dīn Ṭūsī under Abāqā (663-80/1256-82).
