"But Islam was never accepted as a dharma by mainstream Hinduism. It was only in the fourteenth century of the Christian era that we meet the so-called Nirguna school of bhakti or santamata, founded by Kabir, which started treating Islam as a way of worship and even equating it with Hindu Dharma - Rama with Rahim, Veda with Kateb (Kitâb, the Book or Quran) Kashi with Ka'ba, Pandit with Mullah, Temple Bells with Azan, and so on. Quite a bit of this equating was done for ridiculing the rituals of both Islam and Hinduism, and proclaiming that the spiritual secret was known only to the sadguru, the True Teacher like Kabir. For the rest, the bulk of the santamata literature is Vaishnavite derived from the Puranas, particularly the Bhâgavata-purâNa. The only variation is the mention of a few sufis like Mansur Al-Hallaj, Abu Yazid (Bayazid) and Adham Sultan, who were hardly sufis like those we meet in the latter day silsilas (orders). It is significant that none of the sufis from the silsilas finds place in this literature.... The main-stream Bhakti Movement which was wide-spread among Hindus including those belonging to most of the lower castes, always looked down upon the santamata, even when the latter became increasingly more and more Hindu except for its incongruent streaks of monotheism, prophetism (guruvâda) and anti-Brahminism. It is significant that no adherent of any school of Santamata is known to have converted to Islam. What we know is that some converts to Islam joined its ranks, notably Dadu and Sadhna. So the doctrine of sarva-dharma-samabhâva cannot be attributed to the santamata. What we find in santamata is not equal respect for all religions but equal contempt for all rituals and institutions, whether Hindu or Islamic."
