Abu'l-Qasim Ubaydallah ibn Abdallah ibn Khordadbeh (Persian: ابوالقاسم عبیدالله ابن خردادبه) (c. 820 – 912 CE), better known as Ibn Khordadbeh or Ibn Khurradadhbih, was the author of the earliest surviving Arabic book of administrative geography. He was a Persian geographer and bureaucrat of the 9th century. He was the son of Abdallah ibn Khordadbeh, a prominent Abbasid general, who was the son of a Zoroastrian convert to Islam. Ibn Khordadbeh was appointed "Director of Posts and Intelligence" for the province of Jibal in northwestern Iran under the Abbasid Caliph al-Mutammid (ruled 869–885 CE). In this capacity ibn Khordadbeh served as both postmaster general and the Caliph's personal spymaster in that vital province.
Around 846-847CE ibn Khordadbeh wrote Kitāb al Masālik w’al Mamālik (The Book of Roads and Kingdoms) (with the second edition of the book being published in 885CE). In this work, ibn Khordadbeh described the various peoples and provinces of the Abbasid Caliphate. Along with maps, the book also includes descriptions of the land, people and culture of the Southern Asian coast as far as Brahamputra, The Andaman Islands, peninsular Malaysia and Java. The lands of Tang China, Unified Silla (Korea) and Japan are referenced within his work.
Ibn Khordadbeh clearly mentions Waqwaq twice: East of China are the lands of Waqwaq, which are so rich in gold that the inhabitants make the chains for their dogs and the collars for their monkeys of this metal. They manufacture tunics woven with gold. Excellent ebony wood is found there. And again: Gold and ebony are exported from Waqwaq.
