 In the texts of Delhi Sultanate era, states Sharma, the term Hindu remains ambiguous on whether it means people of a region or religion, giving the example of Ibn Battuta's explanation of the name "Hindu Kush" for a mountain range in Afghanistan.It was so called, wrote Ibn Battuta, because many Indian slaves died there of snow cold, as they were marched across that mountain range.The term "Hindu" there is ambivalent and could mean geographical region or religion.
