Aḥmad ibn Faḍlān ibn al-ʿAbbās ibn Rāšid ibn Ḥammād, commonly known as Ahmad ibn Fadlan, was a 10th-century Muslim traveler, famous for his account of his travels as a member of an embassy of the Abbasid caliph, al-Muqtadir of Baghdad, to the king of the Volga Bulgars, known as his risāla ("account" or "journal"). His account is most notable for providing a detailed description of the Volga Vikings, including eyewitness accounts of life as part of a trade caravan and witnessing a ship burial.
