Is there any mention of the religion Hinduism or Sanatana Dharma (earlier name of Hinduism) in any of the Islamic scriptures?
The Quran does not mention the name of any religion other than Islam. 3:19
And it doesn't name the followers of any other religion, except for Yahud (Jews), Nasarah (Christians), Majus (Zoroastrians) and Sabieen (Sabeans) and includes the others by saying Mushrikeen (those who do shirk). 22:17
Same goes for the well known hadith of the Prophet, though the region of India is mentioned in some hadith as هند (Hind) and (possibly) the people as زط (Zut).
