a comparison between the Čač-Nāma and Arab historians such as Balādhurī [...] bears out the Arab provenance of those parts of the book that describe the battles leading to the conquest of Sind; Kūfī might well have used Madāʾinī’s "Kitāb Thaghr al-Hind" and "Kitāb ʿUmmāl" (or "Aʿmāl") "al-Hind" [...] The Čač-Nāma seems to have preserved Madāʾinī’s tradition concerning India in a much fuller fashion than classical Arab histories. On the other hand, the book also comprises a considerable amount of material which probably reflects a local Indian historical tradition. The part dealing with the rise of the Čač dynasty (14-72), the story of Darōhar, Djaysinha and Djanki (229-234), and some traditions attributed to a Brahman called Rāmsiya (179) and to “some Brahman elders” ("baʿḍī mashāyikh-i barāhima") (197; cf. also 20614) deserve to be mentioned in this context.
