This article presents a very rare manuscript of a Muntakhab al-Suwar (selection of Qur’anic chapters) calligraphed by Ibrāhīm Sulṭān b. Shāhrukh. This manuscript was transcribed in large format in Ramaḍān 830 AH/June 1427 AD and endowed to the holy shrine of Shāh-Chirāgh in Ramaḍān 834 AH/May‒June 1431 AD. Therefore, it is considered to be one of the last known works calligraphed by Ibrāhīm Sulṭān. It is kept in the Pars museum in Shiraz. In this article, the unique codicology and special characteristics of this masterpiece are studied, and the important historical aspects of Ibrāhīm Sulṭān and the art works attributed to him are elaborated. The style of his calligraphy will also be examined to find out the sources of inspiration for his distinct style.
