The Persian term Hind%u016B is derived from Sindhu, Sanskrit for the Indus River.[9] The Rig Veda mentions the land of the Indo-Aryans as Sapta Sindhu (the land of the seven rivers in northwestern South Asia, one of them being the Indus). This corresponds to Hapta H%u0259ndu in the Avesta (Vendidad or Videvdad: Fargard 1.18)%u2014the sacred scripture of Zoroastrianism. The term was used for those who lived in the Indian subcontinent on or beyond the "Sindhu".[10]
