The Twelve Imams are a central belief in Shia Ithna Ashari (Twelver) Islam. This is a clear, informational overview of who they are — for general knowledge, not a Sunni Hadith-based topic.
Introduction — An Important Clarification Before We Begin
This article is written purely for general knowledge and understanding. The belief in 12 specific Imams, in succession, is a core doctrine of Shia Ithna Ashari (Twelver) Islam. It is not a belief held within Sunni Islam, and it is not a topic addressed or sourced from Sahih al-Bukhari or Sahih Muslim, which are Sunni Hadith collections. This article presents the information as it is understood within Shia theology, for readers who simply want to know who these figures are.
An Important Point on Karbala
A common misunderstanding is that all 12 Imams were martyred together at Karbala. This is not accurate, even within Shia belief itself. Only the third Imam, Husayn ibn Ali, was killed at the Battle of Karbala in 61 AH. The other eleven individuals in this list lived and passed away at different times, in different places, across more than two centuries, according to Shia historical and theological accounts — most of them, in the Shia tradition, are believed to have died through poisoning rather than in battle.
The List of the 12 Imams (According to Shia Ithna Ashari Belief)
1. Ali ibn Abi Talib — the first Imam, cousin and son-in-law of the Prophet Muhammad (peace be upon him), and the fourth Caliph in Sunni history.
2. Hasan ibn Ali — the second Imam, elder son of Ali and Fatimah, grandson of the Prophet (peace be upon him).
3. Husayn ibn Ali — the third Imam, younger son of Ali and Fatimah, martyred at the Battle of Karbala in 61 AH.
4. Ali ibn Husayn (Zayn al-Abidin) — the fourth Imam, son of Husayn, who survived Karbala as a young man.
5. Muhammad al-Baqir — the fifth Imam, son of Zayn al-Abidin.
6. Ja'far al-Sadiq — the sixth Imam, a notable scholar from whom the Ja'fari school of Shia jurisprudence takes its name.
7. Musa al-Kazim — the seventh Imam, son of Ja'far al-Sadiq.
8. Ali al-Rida — the eighth Imam, whose shrine in Mashhad, Iran, remains a major site of pilgrimage today.
9. Muhammad al-Jawad (al-Taqi) — the ninth Imam, who became Imam at a young age.
10. Ali al-Hadi (al-Naqi) — the tenth Imam.
11. Hasan al-Askari — the eleventh Imam.
12. Muhammad al-Mahdi — the twelfth Imam, who, according to Shia Ithna Ashari belief, did not die but entered a state of occultation (concealment) as a child, and is believed by Shia Muslims to be alive and to return at a future time.
Why This Information Is Often Searched Around Muharram
Because the third Imam in this list, Husayn ibn Ali, was killed at Karbala, and because Muharram is the month most associated with his remembrance in Shia tradition, many people search for information about all 12 Imams during this period, often assuming a connection between the list as a whole and the events of Karbala specifically. As clarified above, the connection applies only to the third name on the list.
A Note for Sunni Readers
Sunni Muslims hold the first four names on this list — Ali, Hasan, Husayn, and by extension their family — in high esteem as part of the Prophet's household (Ahl al-Bayt) and, in the case of Ali (RA), as the fourth rightly-guided Caliph. However, the specific doctrine of 12 divinely appointed Imams in succession, including the belief in occultation, is not part of Sunni Islamic belief and is presented here purely as informational content about Shia theology.
