*Otherwise, this "Hindu" term is not seen in any Vedic literature*
" The people known as Hindus in the world, the Hindu is a term given by the Mohammedans, from "Indus." Indus River is there. Now it is in Pakistan. So people beyond the Indus River, the Mohammedans in Arabia and other countries, they pronounce "s" as "h". Instead of "Sindhu," they used to pronounce it as "Hindu." So people living, crossing the river Indus or Hindus, they were called "Hindus." Otherwise, this "Hindu" term is not seen in any Vedic literature. "
