Shiites themselves are unaware of the fact that their own Imams were always condemning and criticising the Shiites for their constant evil.

Narrated Muhammad, Narrated al-Mughira al-Dhabbi: The nobels of the Kufans were insincere to Ali. Their hearts were with Muawiyah because Ali used to give no one more than his due of 2000 Dirham from the booty, while Muawiyah used to give any nobleman an additional 2000 Dirham.? (Al-Gharaat: Ibn Hilall al-Thaqafi p. 29)

Narrated Abdul-Malik bin Maysara, from Umara bin Umair saying: Ali used to have a friend nicked Abu Maryam from al-Madeenah, when he heard that the people have dispersed away from Ali, came to meet with him. When Ali [as] saw him, he said: Abu Maryam? He said: yes. (Ali) said: What came you here to do? He said: I did not come here for any (material) need, but I was thinking all along, that if you were installed in charge of this Ummah, you are over qualified. Ali replied: O Abu Maryam, I am still the same person you have known, but I am tried with the most wicked people on the face of earth. I call them, and they don’t follow me, and if I budge to what they want they disperse away from me? (Ibid, p.44)

Imâm Ja’far is reported as having said:
No verse did Allâh reveal in connection with the Munâfiqîn, except that it is to be found in those who profess Shî’ism
[Abdullâh al-Mâmaqânî, Miqbâs al-Hidâyah vol. 2p. 407]

It is about them that Imâm Ja’far is reported to have said:
No one bears us greater hatred than those who claim to love us. (Abdullâh al-Mâmaqânî, Miqbâs al-Hidâyah vol. 2 p. 414 (Mu’assasat? al-Bayt li-Ihyâ’ at-Turâth, Beirut 1991) quoting from Rijâl al-Kashshî )

Imam Jaffar also does not rely on his Shiites:
Narrated Ali bin Ibrahim? from Ibn Riab: I heard Abu Abdullah (al-Baqir) saying to Abu Basir: By Allah, If I can only find three of you to be truly believers who would conceal my hadith I wont hide any hadith from them? (al-Kafi: al-Kulayni, vol.2, p.242, Chapter: The Few Number of Believers.)

Before Husayn, his elder brother Hasan was the victim of the treacherousness of the Kûfans. In his book al-Ihtijâj the prominent Shî’î author Abû Mansûr at-Tabarsî has preserved the following remark of Hasan:
By Allâh, I think Mu’âwiyah would be better for me than these people who claim that they are my Shî’ah.
Abû Mansûr at-Tabarsî, al-Ihtijâj vol. 2 p. 290-291 (Mu’assasat al-A’lamî, Beirut 1989)

When Hasan eventually became exasperated at the fickleness of his so-called Shî’ah, he decided to make peace with Mu’âwiyah. When someone protested to him that he was bringing humiliation upon the Shî’ah by concluding peace with Mu’âwiyah, he responded by saying:
By Allâh, I handed over power to him for no reason other than the fact that I could not find any supporters. Had I found supporters I would have fought him day and night until Allâh decides between us. But I know the people of Kûfah. I have experience of them. The bad ones of them are no good to me. They have no loyalty, nor any integrity in word or deed. They are in disagreement. They claim that their hearts are with us, but their swords are drawn against us.

Abû Mansûr at-Tabarsî, al-Ihtijâj vol. 2 p. 290-291 (Mu’assasat al-A’lamî, Beirut 1989

Before the incident of karbala 18,000 Shiis of kufa pledged alleigence to Imam hussain,when imam hussain was on his way to Kufa he recieved the news that his cousin was abandoned by the shiis and was killed by the yezidi ruffian ubaidullah.ubaidullah at that time had only 4000 troops,the shiis had greatly outnumbered them,inspite of that the kufians rejected to join imam hussain and left him all alone with his family to be maytred in karbala.
Karbalâ was not to be the last act of treason by the Shî’ah against the Family of Rasûlullâh sallallâhu ‘alayhi wa-âlihî wasallam. Sixty years later the grandson of Sayyidunâ Husayn, namely Zayd ibn ‘ Alî ibn Husayn, led an uprising against the Umayyad ruler Hishâm ibn ‘Abd al-Malik. He received the oaths of allegiance of over 40 000 men, 15 000 of whom were from the very same Kûfah that deserted his grandfather. Just before the battle could start they decided upon a whim to ask his opinion about Abû Bakr and ‘Umar. Zayd answered: “I have never heard any of my family dissociate himself from them, and I have nothing but good to say about them.” Upset with this answer, they deserted him en masse, deciding that the true imâm could only be his nephew Ja’far as-Sâdiq. Out of 40 000, Zayd was left with only a few hundred men. On the departure of the defectors he remarked: “I am afraid they have done unto me as they did to Husayn.” Zayd and his little army fought bravely and attained martyrdom. Thus, on Wednesday the 1st of Safar 122 AH another member of the Ahl al-Bayt fell victim to the treachery of the Shî’ah of Kûfah.6 This time there could be no question as to whether those who deserted him were of the Shî’ah or not. The fact that the thousands of Shî’ah who deserted Zayd ibn ‘Alî looked upon Ja’far as-Sâdiq as their true Imâm shows that by and large they were the same as the Ithnâ ‘Asharî, or alternatively Imâmî or Ja’farî Shî’ah of today. Why then, if he had so many devoted followers, did Imâm Ja’far not rise up in revolt against the Umayyads or the ‘Abbâsids? The answer to this question is provided in a narration documented by Abû Ja’far al-Kulaynî in his monumental work al-Kâfî, which enjoys unparallelled status amongst the hadîth collections of the Shî’ah:
Sudayr as-Sayrafî says: I entered the presence of Abû ‘Abdillâh ‘alayhis salâm and said to him: “By Allâh, you may not refrain from taking up arms.” He asked: “Why not?” I answered: “Because you have so many partisans, supporters (Shî’ah) and helpers. By Allâh, if Amîr al-Mu’minîn (Sayyidunâ ‘Alî) had as many Shî’ah, helpers, and partisans as you have, Taym (the tribe of Abû Bakr) and ‘Adî (the tribe of ‘Umar) would never have had designs upon him.” He asked: “And how many would they be, Sudayr?” I said: “A hundred thousand.” He asked: “A hundred thousand?” I replied: “Yes, and two hundred thousand.” He asked again: “Two hundred thousand?” I replied: “Yes, and half the world.” He remained silent.

Then he said: “Would you accompany us to Yanbu’?” I replied in the affirmative. He ordered a mule and a donkey to be saddled. I quickly mounted the donkey, but he said: “Sudayr, will you rather let me ride the donkey?” I said: “The mule is more decorous and more noble as well.” But he said: “The donkey is more comfortable for me.” I dismounted. He mounted the donkey, I got on the mule, and we started riding. The time of salâh arrived and he said: “Dismount, Sudayr. Let us perform salâh.” Then he remarked: “The ground here is overgrown with moss. It is not permissible to make salâh here.” So we carried on riding until we came to a place where the earth was red. He looked at a young boy herding sheep, and remarked: “Sudayr, by Allâh, if I had as many Shî’ah as there are sheep here, it would not have been acceptable for me to refrain from taking up arms.” We then dismounted and performed salâh. When we were finished I turned back to count the sheep. There were seventeen of them
al-Kulaynî, al-Kâfî (Usûl) vol. 2 p. 250-251 (Dâr al-Adwâ, Beiru1992)
Imâm Mûsâ al-Kâzim, the son of Imâm Ja’far, and the seventh of the supposed Imâms of the Shî’ah, describes them in the following words:

If I had to truly distinguish my Shî’ah I would find them nothing other than pretenders. If I had to put them to the test I would only find them to be apostates. If I were to scrutinise them I would be left with only one in a thousand. Were I to sift them thoroughly I would be left with only the handful that is truly mine. They have been sitting on cushions all along, saying: ” We are the Shî’ah of ‘Alî.”
al-Kulaynî, Rawdat al-Kâfî vol. 8 p. 288

Bearing of all that in mind it is evident that the worst type of people surrounded the imams.isnt it possible that these pretenders could have fabricated out of their own selves concepts like “imamah”,”high status of ali”,”calling unto the members of the ahlul bayt”,”infallibality of the ahlul bayt”,”hypocrisy of the prophet’s companions”,”unfaithfulness of the prophet’s wives” etc…………and then narrated to others ascribing them as sayings of the prophet and the ahlul bayt, the next passage sheds more light on this:
Some of the most prolific narrators of the Shi’ah are

Zurarah ibn A`yan
Muhammad ibn Muslim at-Ta’ifi
Abu Basir Layth ibn al-Bakhtari al-Muradi
al-Mufaddal ibn ‘Umar al-Ju’fi

Zurarah ibn A’yan

Sayyid Bahr al-‘Ulum states that the family of A’yan, of which Zurarah was a scion, was the largest Shi’i family of Kufa. (Rijal as-Sayyid Bahr al-‘Ulum, a.k.a al-Fawa’id ar-Rijaliyyah, vol. 1 p. 222)

Zurarah has always posed a problem in Shi’ism, because while is on the one hand regarded as the most prolific narrator from the Imams al-Baqir and as-Sadiq, the Imams are also recorded as having cursed and excommunicated him. The Shi’ah attempt to reconcile these two contradictory attitudes through the dubious and completely unconvincing explanation of taqiyyah by the Imams.

Regarding the wealth of narrations which Zurarah reports, we are informed by al-Kashshi that had it not been for Zurarah, the ahadith of al-Baqir would have been lost. (Ikhtiyar Ma’rifat ar-Rijal vol. 1 p. 345) Sayyid Abul Qasim al-Khu’i has counted 2094 of his narrations in the four books, all of them from the Imams al-Baqir and as-Sadiq, (al-Khu’i, Mu’jam Rijal al-Hadith vol. 7 p. 249)

On the other hand, al-Kashshi records that Imam Ja’far as-Sadiq cursed Zurarah. The following quotation is but one of several places where his cursing of Zurarah is on record:

By Allah, he has ascribed lies to me! By Allah, he has ascribed lies to me! By Allah, he has ascribed lies to me! May Allah curse Zurarah! May Allah curse Zurarah! May Allah curse Zurarah! (Ikhtiyar Ma’`rifat ar-Rijal, vol. 1 p. 361)

Despite Imam Ja’far as-Sadiq’s cursing of Zurarah, he is still accepted by the Shi’ah as the most prolific and reliable authority for the ahadith of the Imams. He hails from Kufa, the centre of the successors of Ibn Saba; he is cursed by the Imam as Ibn Saba was cursed by Sayyiduna ‘Ali; and yet he is respected as a trustworthy and reliable narrator of the ahadith which form the basis of Shi’ism!

Muhammad ibn Muslim
Muhammad ibn Muslim is another Kufan narrator whose credentials as a narrator are extremely suspect, but who is accepted by the Shi’ah as a reliable narrator all the same. This Muhammad ibn Mus, who claims to have heard 30 000 ahadith from Imam Muhammad al-Baqir, and a further 16 000 from his son Imam Ja’far as-Sadiq (See Ikhtiyar Ma’rifat ar-Rijal vol. 1 p. 391) is also recorded by al-Kashshi to have been cursed by Imam Ja’far as-Sadiq (vol. 1 p. 394) just as Ibn Saba was cursed by his great-grandfather!

Abu Basir al-Muradi

In Abu Basir we have another very prolific Kufan narrator whose character fails to convince anyone of his trustworthiness. He, together with Zurarah, is regarded of those who preserved the legacy of the Imams al-Baqir and as-Sadiq. He is one of a very select group of narrators about whom it is said that “there is consensus amongst the Shi’ah to accept what is authentically narrated from them.” (See al-Mamaqani, Miqbas al-Hidayah vol. 2 p. 171)

However, Mir Damad in his annotations to Rijal al-Kashshi notes that the Shi’i hadith critic Abul Husayn ibn al-Ghada’iri said of him:

Abu ‘Abdillah (Imam Ja’far as-Sadiq) used to get annoyed and upset with his presence, and his companions are in disagreement amongst themselves about him. I (Ibn al-Ghada’iri) believe that he was cursed on account of (matters pertaining to) his religion, not his narrations. To me he is a trustworthy narrator. (Ikhtiyar Ma’`rifat ar-Rijal, vol. 1 p. 397. See also al-Ardabili, Jami’ ar-Ruwat vol. 3 p. 43)

Again we have here a most prolific Kufan narrator who was cursed by Imam Ja’far as-Sadiq just like Ibn Saba was cursed by Sayyiduna ‘Ali!

al-Mufaddal ibn ‘Umar

Here we have another Kufan narrator who is regarded by eminent Shi’i hadith critics as a reliable transmitter of the Imams’ hadith. Al-Ardabili in Jami’ ar-Ruwat (vol. 2 p. 258) records that Shaykh Mufid mentioned al-Mufaddal as belonging to the “inner circle, reliable and pious Fuqaha” of Imam Ja’far as-Sadiq’s followers. Abu Ja’far at-Tusi too, is quoted as having mentioned al-Mufaddal amongst the mamduhin (praiseworthy).

But Imam Ja’far is recorded by al-Kashshi to have addressed by calling him, “You Kafir! You Mushrik!” (See Ikhtiyar Ma’rifat ar-Rijal vol. 2 p. 612) Another lengthier narration of al-Kashshi runs as follows:

‘Abdullah ibn Miskan says: Hujr ibn Za’idah and ‘Amir ibn Judha’ah al-Azdi came to Abu ‘Abdillah [Imam Ja’far] and told him: “May we be ransomed for you! Mufaddal says that you [the Imams] determine the sustenance of the people.” He [Imam Ja’far said]: “By Allah, no one besides Allah determines our sustenance. One day I needed food for my family. I was under difficult circumstances and thought hard about it, until I managed to secure food for them. Only then did I feel content. May Allah curse him and disown him.” They asked: “Do you curse and disown him?” He replied: “Yes, so you too, curse him and disown him. May Allah and His messenger disown him.” (Ikhtiyar Ma’rifat ar-Rijal vol. 2 p. 614)

The above narration clearly identifies al-Mufaddal with the heresy originally introduced by Ibn Saba. In the biography of Ibn Saba given in al-Kashshi’s Rijal, Imam al-Baqir is reported to have stated that Ibn Saba claimed himself to be a prophet, and ‘Ali to be Allah (See Ikhtiyar Ma’rifat ar-Rijal vol. 1 p. 323). If we return to al-Mufaddal’s biography in the same book we find the following:

Al-Kashshi says: The extremist Tayyarah mention in some of their books on the authority of al-Mufaddal that he said: “Seventy prophets were killed with Abu Isma’il, meaning Abul Khattab, each one of whom had seen and announced his prophethood.”

[They also say] that he said: Twelve of us were admitted to the presence of Abu ‘Abdillah [Imam Ja’far as-Sadiq]. Abu ‘Abdillah started greeting each one of us, calling each of us by the name of a prophet. To some he said, “Peace be upon you, O Nuh.” To some he said, “Peace be upon you, O Ibrahim,” To last one he greeted he said, “Peace be upon you, O Yunus.” Then he said, “Do not distinguish between the Prophets.” (Ikhtiyar Ma’rifat ar-Rijal vol. 2 p. 614)

This Mufaddal, whom al-Kashshi says was of the extremist Khattabiyyah sect, the followers of Abul Khattab, whose beliefs derived directly from Ibn Saba himself-this Mufaddal is exonerated by contemporary Shi’i scholars such as Shaykh ‘Abdullah al-Mamaqani, and Sayyid Abul Qasim al-Khu’i as a most reliable and trustworthy transmitter of the knowledge of the Imams. Al-Mamaqani gives a lengthy explanation about what exactly constitutes ghuluww (See Tanqih al-Maqal vol. 3 p. 240 and Miqbas al-Hidayah vol. 2 p. 397) and concludes that the kind of things on account of which al-Mufaddal was labelled as a ghali has since become of the undeniable tenets (daririyyat) of Shi’ism.
The other important thing is that most of the Shii narrations go this way:It has been reported regarding Muhammad bin Isma’eel by way of some of our friends through a man who transmitted it from him [‘Ali] that he said…” Their books are filled with hundreds of thousands of traditions whose authenticity cannot be confirmed.who knows if “some of our friends” or the “man” was a pretender or a hypocrite about whom imam Musa kazim and imam Jaffar as sadiq complained???
This proves that shii beliefs and shii narrations from the imams and the prophet are untrustworthy.May Allah be praised for revealing the truth and showing his servant what the right path is.
It is no wonder that Ibn Abil-Hadeed, an extremist Shi’i clergyman, admitingly writes in his Sharh Nahjul-Balaghah:
“The origin of lies in Ahadith of virtues, started with the Shi’ah who fabricated various Ahadith in the virtues of their Aimmah. It was the enmity they held against their adversaries that drove them to fabricate them” [Sharh Nahujul-Balaghah, vol.1, p.783 (Quoting from ash-Shi’a wat-Tashayyu’, p.19)]”
