“As we have explained several times, however, we find no such word as ‘Hindu’ in the Vedic literature. The word most probably came from Afghanistan, a predominantly Muslim country, and originally referred to a pass in Afghanistan known as Hindukush that is still a part of a trade route between India and various Muslim countries.” (Shrila Prabhupada, Chaitanya Charitamrita, Adi 12.73 Purport)
