"It is often said that the 15th-century poet Kabir was neither a Hindu nor a Muslim because he criticized and mocked both Hinduism and Islam, or rather, both Hindus and Muslims... Thus, Kabir’s rejection of Islamic animal sacrifice... does pit him against Islam as such. But Hinduism has far more fluid boundaries: most things Hindu have been rejected at one time or other by authoritative thinkers whose inclusion in the Hindu category is not in doubt... Kabir’s relative originality lies in his combination of devotion with the conception of the object of devotion as faceless (nirguna, “without quality”) rather than iconographically distinct, but that doesn’t place him outside the Hindu continuum... Scholars who place Kabir (or Sikhism founder Guru Nanak) as much outside Hinduism as outside Islam, may be suspected of projecting non-Hindu, mainly Christian categories of box-type religious divisions onto a civilization in which they don’t apply."
