Ziyarat

The correct answer is Option (2) → Ziyarat

When the shaikh died, his tomb shrine (dargah, a Persian term meaning court) became the center of devotion for his followers. This encouraged the practice of pilgrimage or ziyarat to his grave, particularly on his death anniversary or urs.

The pilgrimage to the tombs of Sufi saints is termed as "Ziyarat" in Sufi Islam. During these pilgrimages, devotees visit the tombs or shrines of Sufi saints to seek blessings, offer prayers, and pay their respects. These visits are an integral part of Sufi practices and involve acts of devotion and reverence at the shrine or tomb of the Sufi saint.
