バクトリア語
Some Arabic sources erroneously describe the vihāra as a fire temple of Zoroastrianism, presumably because of its proximity to Balkh, Zoroaster's birthplace. In Arabic sources, the monastery's name is represented as "Naubahar". Van Bladel (p. 68) has pointed out that this version of the name can be traced to the pronunciation in the Bactrian language.
