ʿABD-AL-VĀḤED B. MOḤAMMAD, 8th/14th century author. There is no positive proof that this individual was a Persian, though his association with Persians makes that conclusion plausible. His extant commentary on Naṣīr-al-dīn Ṭūsī’s Sī faṣl dar taqwīm or Resāla fī maʿrefat al-taqwīm (“Epistle on knowing the calendar”) was composed in 797/1394-95, while Ḥāǰǰī Ḵalīfa ascribes to him a commentary on the Molaḵḵaṣ fiʾ l- hayʾa (“Compendium of astronomy”) written by Jaḡmīnī in the early 14th century, as well as a Manẓūma fiʾ l-asṭorlāb (“Didactic poem on the astrolabe”), which he composed for his pupil, Moḥammad Šāh Fenārī.
