Shi’a Muslims believe that imams are inspired by God, are without sin and are infallible, which means that they can interpret the teachings of the Qur’an without making any errors.
The Imamate is important to Shi’a Muslims because the imams are without sin and can interpret the Qur’an without fault, they rule justly and are all part of the bloodline of Muhammad, continuing his work and life.
Muhammad al-Muntazar is believed to be alive but hidden, and will one day return with Jesus (Isa) to bring justice and equality, a belief known as The Occultation.
The Shi’a Imams: according to Twelver Shiites, the seventh and last Imam, Isma'il ibn Ja'far, was the son of Jafar al-Sadiq and the father of Muhammad al-Muntazar.
