Why is the tradition of Ziyarat called urs?
Ziyarat means a pilgrimage to tombs of Sufi saints. In other words, it means to seek the Sufi’s spiritual grace, that is, Barakat. When the Shaikh died, his tomb-shrine (dargah) became a center, of pilgrimage or devotion for his followers. So, Ziyarat meant the pilgrimage to the tomb on the death anniversary of the saint. On the other hand, urs meant marriage. It signified the union of his soul with God. The purpose of both is the same. Therefore, Ziyarat is also known as urs.
