[3] `Abd al-Hayy's training took place primarily during the reign of the Jalayirid Shaikh Awais Jalayir, where he soon became a highly regarded and coveted painter due to skill and unique artistry.

During this period, Šams al-dīn spent much of his time and energy instructing ʿAbd al-Ḥayy, where he subsequently became the teacher of Aḥmad b. Ovays.

In one particular art piece, a portrait of a sleeping prince is executed in full color and in a style that is more akin to Jonayd Baḡdādī, another popular miniaturist during that time period.

It is commonly credited to `Abd al-Hayy because of its striking similarity to his marginal drawings in a copy of Ahmad Jalayir's Divan.

In addition, a number of folios that are attributed to the late 14th century and preserved in various albums bear the notation that they were copied from ῾Abd al-Hayy's drawings by Muhammad ibn Mahmud Shah Khayyam.

[8] Another of `Abd al-Hayy's pupils, Ahmad Jalayir created similar monochromatic, black and white drawings to accompany his manuscripts in the Abusa'idnama ('Book of Abu Sa'id').

Evidence for this can be seen in the text of the manuscript that states that the unnamed painter, who was assisted by Aḥmad b. Ovays, prepared an Abū Saʿīd-nāma containing black and white drawings, a signature of `Abd al-Hayy.
