There is no such thing as the ''12 Imams'', the whole Shiism is based on lies
Let’s have a look at what the Messenger of Allah (saw) said regarding the 12 Imams:
Sahih Bukhari Book 89:329
Narrated Jabir bin Samura: ‘’I heard Muhammad say ‘There will be twelve Muslim rulers.’ He then said a sentence which I did not hear. My father said ‘’All of them (those rulers) will be from Quraysh.’’
Sahih Muslim Book 20:4477-4483
Narrated Jabir bin Samura: ‘’I heard Muhammad say ‘The (Islamic) religion will continue until the Hour (Day of Resurrection), having twelve Caliphs for you and all of them will be from Quraysh.’’
Sunan al-Tirmidhi Hadith 2223
The Prophet said: ‘’There will be twelve Amir after me.’ Then he said something that I did not understand. So I asked the one who was next to me, who said that he had said: ‘All of them are from Quraysh.’’
Sunan Abu Dawood Book 37:4266
The Prophet said: ‘’The religion will continue to be established till there are twelve Caliphs over you, and the whole community will agree on each of them.’’
Musnad-e-Ahmad, volume 5, page 87
‘’Surely this religion will always overcome its opponents and no enemy or deserter can ever harm it till there are twelve Caliphs from my nation in it. All of them will be from Quraysh.’’
And there are more than 20 similar narrations. By the way ‘twelve’ is how we spell out the number 12 using letters in case you weren’t aware.
As you may know, the followers of the Members of the House of the Prophet (saw) refer to these 12 Caliphs as of their 12 Imams starting with Imam Ali (as) and ending with Imam Mahdi (as) the Leader of our time. With the passage of time and through historical events, we know that by the above traditions the Holy Prophet (saw) meant the twelve Imams from his Ahlulbayt (as) who are the descendants of the Prophet since we have no other 12 pure candidates in the history of Islam upon whose righteousness all Muslims agree. It is interesting to know that even the enemies of Shias have NOT been able to find any fault in the virtues of the twelve Imams of the Shias.
It is now clear that the only way to interpret the previously mentioned traditions which are narrated by al-Bukhari, Muslim, Abu Dawood, al-Tirmidhi, and Ahmad Ibn Hanbal is to accept that it refers to the twelve Imams from the Prophet’s Ahlulbayt, because they were, in their times, the most knowledgeable, the most illustrious, the most god-fearing, the most pious, the best in personal virtues, and the most honored before Allah; and their knowledge was derived from their ancestor (the Prophet) through their fathers. These are the Ahlulbayt (as) whose sinlessness, flawlessness, and purity is confirmed by the Holy Quran (the last sentence of verse 33:33).
It’s amazing that despite the acknowledgment of al-Bukhari and Muslim and other prominent Sunni scholars about the twelve Imams, the Sunnis always stop at the four Caliphs. More interestingly, there are Sunni reports in which the Messenger of Allah (saw) named these twelve members of his Ahlulbayt (as) one by one starting with Imam Ali (as) and ending with Imam Mahdi (as). (Source: Yanabi al-Mawadda, page 431 by al-Qunduzi al-Hanafi).
Nowehere in Sunnism are there twelve Muslim rulers who, all of them are from Quraysh. The ‘Four Rightly Guided’ Rashidun Caliphs were four, there were more than 30 Ummayad Caliphs, nearly 40 Abbasid Caliphs, and many Sunni Caliphs are not even from Quraysh.
Now let’s count the Shia Imams/Caliphs:
1) Imam Ali Ibn Abi Talib (as)
2) Imam Hassan Ibn Ali (as)
3) Imam Hussain Ibn Ali (as)
4) Imam Ali Ibn Hussain (as)
5) Imam Muhammad Ibn Ali (as)
6) Imam Jafar Ibn Muhammad (as)
7) Imam Musa Ibn Jafar (as)
8) Imam Ali Ibn Musa (as)
9) Imam Muhammad Ibn Ali (as)
10) Imam Ali Ibn Muhammad (as)
11) Imam Hassan Ibn Ali Ibn Muhammad (as)
12) Imam Muhammad al-Mahdi (may Allah hasten his reappearance)!
