Wikipedia
A Dargah ( dargâh or dargah, also in Urdu) is a shrine built over the grave of a revered religious figure, often a Sufi saint or dervish. Muslims may visit the shrine for ziyarat, a term associated with religious visits and pilgrimages. Dargahs are often associated with Sufi meeting rooms and hostels, called khanqah or hospices. They usually include a mosque, meeting rooms, Islamic religious schools ( madrassas), residences for a teacher or caretaker, hospitals, and other buildings for community purposes.
Some Muslims do not believe in the practice of constructing over graves and turning them into places of worship, and consider it as associating partners to God or shirk, though visiting graves is encouraged. Muhammad (according to some sects) forbade turning graves into places of worship. but encouraged to visit the graves to remember life after death (sahih Muslim 977).
