[4] It is in the Zagros Mountains, about 90 kilometers from the province's capital city Kermanshah, and consists of two valleys; that of Gavehrud and Shajarud.

[6] Based on these arguments, Sonqor might have therefore corresponded to the medieval district of Maybahradj as noted by Al-Baladhuri (died 892), which was separated from Dinavar under Abbasid Caliph Al-Mahdi (r. 775–785) and joined to Sisar.

[6] To its northeast, the city of Sonqor is bordered by mount Pandjeh Ali; behind this mountain runs the road from Hamadan to Sanandaj.

[6] The second edition of the Encyclopaedia of Islam notes that Sonqor, in the "strict sense", is neighboured by the (more northern) district of Kulya'i "on the upper course" of the Gawarud.

[6] This route avoided the predominantly Kurdish territory of Sanandaj and followed a detour through Bijar (Garrus) and Sonqor, eventually reaching Kermanshah within a day's march.
