The text of the tenth chapter of the fifth book of “The Canon of Mas’ud” by Abu Reyhan Biruni given in the work is considered one of the few parts of the work translated into Tajik. Translation was carried out from the Russian edition of 1973. To clarify the spelling and compare some toponyms, three manuscripts of the “Canon of Mas’ud” and its Arabic text from 1956, published in Hyderabad, were partially used. In order to clarify the Tajik version of writing and reading toponyms, the author of the translation turned to the Tajik publications “Osor-ul-bokiya” and “Kitob-ut-tafhim” by Abu Reyhan Biruni, and also used information from “Hudud-ul-olam”. The translation includes part of the chapter where we talk about the longitude and latitude of cities and other settlements of the so-called “historical Tajikistan”. The text is not annotated. The translator, noting the difficulties of translating the works of Abu Reyhan Biruni, pays tribute to the authors of the Russian edition of the “Canon of Mas’ud” and notes its importance in the study and popularization of the studied work of Aburaikhon Biruni.
