Visit JamKaran Mosque near Qom
Shias widely believe that the Imam has said that his followers must pray four Rakaat Salaat in this Masjid, the benefits of which are equivalent to praying inside Khan-e-Ka'aba in Mecca. There is a well behind the mosque and it is customary for pilgrims to write an areeza (request) asking the Imam to take their petitions and pleas to Allah (SWT) and put them in this well.
