Some Sufi and other Muslims believe that dargahs are portals by which they can invoke the deceased saint's intercession and blessing (as per "tawassul", also known as "dawat-e qaboor"[Persian: "da‘wat-i qabũr"دعوتِ قبور, "invocations of the graves or tombs"] or "‘ilm-e dawat" [Persian: "‘ilm-i da‘wat" عِلمِ دعوت, "knowledge of invocations"]). Still others hold a less important view of dargahs, and simply visit as a means of paying their respects to deceased pious individuals or to pray at the sites for perceived spiritual benefits.
