They are misinformed. While it is true that Sufism is integral to Indian Islam In fact probably more so than in other countries, Sufism can be traced back to early Islamic community only being organised into Sufi Tariqata or Orders around the Eleventh century. Sufism before then was a movement centred on mysticism and the search for the divine truth. The Shadhiliya was founded in Morocco, the Qadiriyya and Naqshbandi Persian while the Chistiyyah has Afghan-Indian roots. Even then these Sufi Orders further developed to the point where one could belong to the same Sufi Order and yet also belong to a further sub-order which for the most part was organised by the region, nation or even Province of said Sufi. To say that Sufism is Indian would be to disregard the traditions of other nations with ancient Sufi traditions such as Iran, Yemen, Indonesia and Morocco to name a few.
