Masuleh village has a rich history, which is evident in many of its religious buildings, including the tomb of Aun bin Muhammad Hanafiyah bin Ali (AS). The history of this court, which is located in the heart of the village, dates back to the 2nd or 3rd century AH and is a testimony to the cultural heritage of Masuleh. In addition to the court, there are three shrines inside this beautiful village, one of which is the tomb of Aun bin Muhammad Hanafiyah bin Ali (AS).

This mausoleum is part of a religious complex that includes a mosque located to the west and east of it. Two new minarets have been erected around the dome of this mosque, which increases its impressive architectural beauty.

The exteriors of the Imamzadeh are decorated with intricate brickwork and arches, while the interiors have equally impressive arches.

Today, it is one of the 1200 tombs that are located inside the historical monuments of Iran. Many tourists visit Masuleh every year to admire the shrine of Aun bin Muhammad Hanafiyah bin Ali (peace be upon him) and to pay respect to the grandson of Hazrat Ali (peace be upon him).
