Jamkaran (Persian: جمكران), also Romanized as Jamkarân, Jamkarān and Jam'karân; also known as Jamgarân (جمگران) and Jam-e-Karân (جم کران), was a village in Qanavat Rural District of the Central District of Qom County, Qom province, Iran.
At the 2006 census, its population was 8,368 in 1,747 households.[2]
Jamkaran is located on the outskirts of Qom, and is the site of the Jamkaran Mosque, a popular pilgrimage site for Shia Muslims from all over the world. Shia belief has it that the Mahdi—the Twelfth Shia Imam, a figure from Shia eschatology who will lead the world to an era of universal peace—once appeared and offered prayers at Jamkaran.
On Tuesday evenings large crowds of thousands gather at Jamkaran to pray and to drop a note to the Imam in a well at the site, asking for help with some problem.[3]
