A Sufi dargah (a religious cemetery of a Sufi saint where people worship) on IIT Roorkee campus, Roorkee, India. Sufism in India was an ascetic, mystical, Islamic religious movement traveling with central Asian invasions from 12th century onwards, and that would combine some of the Islam, and Bhakti Hinduism traditions, and that to this day finds devotees from many different religions across India. It would also later influence the teachings of Sikhism. People make offerings, and prayers at Sufi dargahs.
Sufism as a whole has a larger, and longer history beyond India, and started in present-day Iraq, and covers vast part of Middle East, and Asia.
