It is not pilgrimage site and according Wikipedia:
In the Hijri year 23, whilst
Umar had just begun leading the
Fajr (morning) prayer in
Al-Masjid an-Nabawi, Pirouz had hidden the dagger in his robe, the grip of which was in the middle, and hid himself in a corner of the
mosque. Shortly after
Umar had begun the prayer, Pirūz leaped upon him and stabbed him six times (only three times, according to Ibn Sa'd), this was five times in the stomach and once in the navel which proved fatal. Pirūz made his way out of the mosque, wounding thirteen men who tried to stand in his way.Six to nine of the men later died.
Pirūz Nahavandi's tomb is located on the road from
Kashan to Fins, constructed in an eleventh-century distinctive Persian-Khwarezmian dynastic architectural style, consisting of a courtyard, porch and conical dome decorated with turquoise coloured tiles, and painted ceilings. The original date of its construction is unknown, but in second-half of fourteenth century it was fully restored and a new tombstone was placed over his grave."
Controversy was caused recently when, in 2010, the
International Union for Muslim Scholars called for the tomb to be destroyed, a request which was not well received by some Iranians, having been perceived as a specifically anti-Iranian act. The tomb is used as the local police head office.
