Question

What is the name of that persian who used the term hindustan for the first time and when?

Answer 1

Hindustan is derived from the Persian word Hindū cognate with the Sanskrit Sindhu. The Proto-Iranian sound change  occurred between 850–600 BCE, according to Asko Parpola. Hence, the Rigvedic sapta sindhava (the land of seven rivers) became hapta hindu in the Avesta. It was said to be the "fifteenth domain" created by Ahura Mazda, apparently a land of 'abnormal heat'. In 515 BCE, Darius I annexed the Indus valley including Sindhu, the present day Sindh, which was called Hindu in Persian. During the time of Xerxes, the term "Hindu" was also applied to the lands to the east of Indus
