Ahmad ibn Rustah

His information on the non-Islamic peoples of Europe and Inner Asia makes him a useful source (to the Muslims) for these obscure regions (he was even aware of the existence of the British Isles and of the Heptarchy of Anglo-Saxon England) and for the prehistory of the Turks and other steppe peoples.

He travelled to Novgorod with the Rus', and compiled books relating his own travels, as well as second-hand knowledge of the Khazars, Magyars, Slavs and other peoples.

He wrote most extensively about his native city of Isfahan.
He wrote of tenth-century Novgorod, a city of the Rus':
:"As for the Rus, they live on an island … that takes three days to walk round and is covered with thick undergrowth and forests; … They harry the Slavs, using ships to reach them; they carry them off as slaves and … sell them. They have no fields but simply live on what they get from the Slav's lands … When a son is born, the father will go up to the newborn baby, sword in hand; throwing it down, he says, 'I shall not leave you with any property: You have only what you can provide with this weapon.'" (1)

His impression of the Rus' is very favourable (especially compared to the relation of Ibn Fadlan):
:"They carry clean clothes and the men adorn themselves with bracelets and gold. They treat their slaves well and also they carry exquisite clothes, because they put great effort in trade. They have many towns. They have a most friendly attitude towards foreigners and strangers who seek refuge."

He also gives an account of a funeral at Birka.

Of ancient Croatia he wrote in the chronicle Al-Djarmi:
:"Their ruler is crowned … He dwells in the midst of the Slavs … He bears the title of 'ruler of rulers' and is called 'sacred king'. He is more powerful than the zupan (viceroy), who is his deputy … His capital is called Drzvab where is held a fair of three days every month."

About a certain king of the Caucasus Ibn Rustah wrote:
:"He prayed on Fridays with the Muslims, on Saturdays with the Jews and on Sundays with the Christians. 'Since each religion claims that it is the only true one and that the others are invalid', the king explained, 'I have decided to hedge my bets.'"

He also travelled extensively in Arabia and is one of the early Arab explorers to describe the city of Sana'a. In his Book of Precious Records, he writes:
:"It is the city of Yemen — there not being found in the highland or the Tihama or the Hijaz a city greater, more populous or more prosperous, of more noble origin or more delicious food than it. … San'a is a populous city with fine dwellings, some above others, but most of them are decorated with plaster, burned bricks, and dressed stones."
