The 30th part of the Quran Ariana, cataloged as number 991 and preserved in the library of Astan Quds Razavi, is one of the last exquisite multi-volume Qurans of Iran, displaying the finest features of Iranian Quranic art.

While details about the scribe, endower, date, and location of its creation remain unknown, its visual characteristics reflect a consistent style that likely originates from one of the prominent centers of Quranic production in Iran during the 9th and 10th centuries AH. The dating of this manuscript, based on its similarities in script and illumination to the Quran of Abdullah Tabakh and Quran number 206, places it within the period of 834 to 975 AH. This volume measures 21 × 29.5 cm and consists of 19 folios, with each page featuring eleven lines written in the scripts of Muhaqqaq, Thuluth, and Naskh.

Part 991, which includes the 30th juz of the Ariana Quran, was probably intended for simultaneous recitation by multiple readers in public spaces like tombs or mosques, particularly during Ramadan. Its connection to the manuscript production center in Herat is supported by its script, illumination, and dimensions.
