The mosque houses a rare handwritten copy of the
Quran that is regarded as the oldest of its kind in China. The manuscript consists of 867 pages in two volumes and is written in Arabic. Experts believe it dates between the 8th and 13th centuries. According to the
National Catalogue of Precious Ancient Books () published by the
Ministry of Culture, the manuscript is listed as a precious ancient book and is dated to the
13th century. Historical accounts state that the Quran was brought to China by the ancestors of the Salar people when they migrated east from
Samarkand about 700 to 800 years ago. The manuscript was handwritten by
Arab Muslims, unlike other early copies in China written by
Chinese Muslims. The mosque museum also displays later printed copies of the Quran, many reflecting traditional Chinese calligraphic styles. == See also ==
