In Shia Islam, the Imamah is a doctrine which asserts that certain individuals from the lineage of the Islamic prophet Muhammad are to be accepted as leaders and guides of the ummah after the death of Muhammad. Imamah further says that Imams possess divine knowledge and authority (Ismah) as well as being part of the Ahl al-Bayt, the family of Muhammad. These Imams have the role of providing commentary and interpretation of the Quran as well as guidance.

Ahl al-Bayt refers to the family of the Islamic prophet Muhammad. In Sunni Islam, the term has also been extended to all descendants of the Banu Hashim and even to all Muslims. In Shia Islam, the term is limited to Muhammad, his daughter Fatima, his cousin and son-in-law Ali, and their two sons, Ḥasan and Ḥusayn. A common Sunni view adds the wives of Muhammad to these five.
Mecca was the birthplace of Muhammad and members of his family, including Ali and Fatima, prior to their migration to Medina in 622. Pictured here is Meccatul Mukarrama Library, also known as Bayt al-Mawlid, because it is believed to stand on the spot where Muhammad was born.
Medina became the home to the Ahl al-Bayt after their migration from Mecca. Pictured in the background is the tomb (marked by the Green Dome) and mosque of Muhammad. In the foreground is the Baqi' cemetery, wherein Hasan and some other relatives of Muhammad are buried.
After the deaths of Muhammad and Fatima in Medina in 632, some of their relatives, including Husayn and Ali, migrated to Iraq and died there. Pictured in the background is the shrine in Najaf where Ali is commonly believed to have been buried, after his assassination in the neighbouring city of Kufa in Iraq.
