An Imāmzādeh (Persian: امامزاده, meaning Imām-born) is a word found in both the Persian and Urdu languages, that refers to an immediate descendant of a Shi'a Imam.
Imamzadeh means “offspring” or descendent of an imam. There are many other different ways of spelling this term. Some of these are imamzada, imamzadah, and emamzadah. These all have the same meanings.
Imamzadeh is also a term for a shrine-tomb of the descendents of Shi’i imams that are directly related to the Prophet Muhammad (PBUH). These shrines are only for the descendants of imams and they are not for imams themselves. Imamzadehs are also sayyids, though not all sayyids are considered imamzadehs. These shrine-tombs are used as centers of Shi’i devotion and pilgrimages. These shrine-tombs are also believed to have miraculous properties and the ability to heal. Many of these are located in Iraq, Medina, India and Iran. There are many important imamzadehs. Many people visit the imamzadehs that are relatively close to them. There are also special ziyaratnameh (pilgrimages) for many of the imamzadehs. Some of these pilgrimages even happen annually during the certain time of year.
