In Shia Islamic theology, the doctrine of Imamate (divine leadership) is one of the five foundational Roots of Religion (Usool al-Deen). Just as Allah (S.W.T) sent Prophets to convey the divine revelation, He appointed twelve purified, infallible successors (Imams) from the lineage of Prophet Muhammad (S.A.W) to safeguard and interpret that revelation for all generations.
The Holy Prophet (S.A.W) declared: “The religion will continue to be established until there are Twelve Caliphs over you, all of them from Quraysh.” (Recorded in Sahih Muslim, Sahih al-Bukhari, and Al-Kafi).
