I must apologize for my absence as I was busy in a debate that required my full attention, I am not getting information from any hate site, but directly from shia source, inshallah hence forth I will make sure  that I do not make any quote with out a link or shia source [refrence]

Let see how "infalible" imam speak about verse of Quran. The verse is this one
ßäÊã ÎíÑ ÃãÉ ÃÎÑÌÊ ááäÇÓ ÊÃãÑæä ÈÇáãÚÑæÝ æÊäåæä Úä ÇáãäßÑ æÊÄãäæä ÈÇááå
When imam Abu Abdullah was asked, how this verse was revealed, he said: "ßäÊã ÎíÑ ÃÆãÉ ÃÎÑÌÊ ááäÇÓ .
This is Quran----3/110. "You are the best of the nations raised up for (the benefit of) men; you enjoin what is right and forbid the wrong and believe in Allah".
And this is the version of imam---You are the best of the imams raised up for (the benefit of) men; you enjoin what is right and forbid the wrong and believe in Allah.

"No one exept imams collected all Quran......"
ßáå -----that is mean all.
So Kulayni named chapter like this.
And there is no doubt that Quran (which is in our hands) WASN'T COLLECTED BY IMAM.

It is atributed to Hz. Ali [ra] in EHTIJAJ TABRISI PAGE# 259
Ameer[as] said Allah named his Nabi[saw] YASIN and revealed in Quran "Salaam Aala Aaley Yasin" Allah did this because He knew that the companions will remove "Aala Aaley Muhammad" from Quran.

Asool Kafi Vol:2 Page#632
Jabbir narrates, He heard Imam Baqir say"Quran fell in sea, people looked for it and when they found the book everything was washed away other than a aya ILLA ALA ALLAH TAZEER ALAL AMOOR [listen all amoor will return to Allah]

Rejecting Accuracy/Integrity of Quran-Fundamental Belief of Shi'ism

The most important, oldest and the most reliable book of creed and fiqh (jurisprudence) for jafri shias is ‘Al-Kafi’ (compiled by Koleni, died in 329 hijri). The part of this book dealing with ‘aqeedah (creed) is known as ‘Usul Kafi’ and the part related to fiqh (jurisprudence) is called ‘Furu’ Kafi’.

We find numerous traditions about Tahreef in Quran in Usul Kafi. In this book there have been put chapters especially on Tahreef in Quran and the effect of such traditions is that the last eminent muhaddith (hadith scholar) of jafri shi’ites, Nuri Tabrasi, in his book Faslul Khitab fee Tahreef Kitab Rabbul Arbab, has not only mentioned 2000 traditions and hadiths of shias over Tahreef in Quran but also stated clearly that all early eminent shia scholars (high ups) except four believe in Tahreef in Quran.

It has also been stated in this book that these four rejectors of Tampering in Quran cannot prove their views using principles of shi’ism.
(In other words their views are based on Taqiyyah so that shias can use their cover at the time of need, saying our these 4 ‘ulama don’t believe in Tahreef in Quran and we also don’t believe in such ‘aqeedah.)

This is not only our claim that (the four) shia ‘ulama who reject tahreef in Quran, do it as Taqiyyah but this fact has been admitted by the famous shia scholar and student of Mulla Baqar Majlisi, Ne’matullah Jazayeri who writes in his book Anwarun Nu’maniyah:

Those who have rejected (‘aqeedah of) Tahreef in Quran (i.e. Shaykh Sudooq, Shareef Murtadha, Tusi and mufassir Tabrasi) have done so due to many considerations (expediency) (i.e. due to taqiyyah to fool sunnis) because they have accommodated such hadiths and traditions in their books in a big number which claim that Quran has undergone tampering and that the so and so verse was revealed this way but later on it was tampered.

(Anwarun Nu’maniyah, printed in Tabrez, 1389 hijri, volume 2, page 257)

Muhaddith Nuri Tabrasi

The importance of muhaddith Nuri Tabrasi one can imagine by the following fact:

Jafri fiqh is based on these 4 books:

1. Kafi
2. Manl-la-yahdharh-al-faqih
3. Tahzib-al-ahkaam
4. Al-istabsar

The collection of all narrations from these books is named as Wasayel-ash-shia which was compiled by Hur ‘Amili.
To this most comprehensive book of shia-hadiths, Nuri Tabrasi has appended a supplement in many volumes with the name of Mustadrak al-wasayel and thus he has perfected shias’ traditions/narrations. On this memorable work of him, he was buried after death near to the presumed shrine of Hadhrat ‘Ali radhiyAllahu 'anhu in Najaf, where his grave is the pilgrim centre for everyone.

Three admissions / confessions of shia scholars believing in Tahree of Quran

These scholars of jafri shias who believe in Tahreef of Quran, openly admit it saying

1. We have numerous traditions/narrations concerning tahreef.

2. These narrations of us clearly imply tahreef in Quran.

3. We belief in tahreef of Quran due to these very narrations.

The expert in shialogy, Maulana Abdush Shakoor Lakhnavi who was the first to introduce this book of Shaykh Nuri Tabrasi in the subcontinent, writes in his book Tambihal-Hayerin under the heading of Three Admissions of shia-scholars which was in response to the booklet of his contemporary shia mujtahid, ‘Ali Hayeri Lahori, the booklet was Mau’izah Tahreef Quran:

1. It says in the book, Faslul Khitab, printed in Iran, page 235:

Many hadiths which are authentic and imply the shortfall and loss in the present Quran, other than those hadiths which have been described in the course of prior arguments and imply that this Quran is less than the amount of descent (nuzool) and this shortfall is not specific to some verse or chapter and these hadiths are diffused in such different books in which our religion confides and to whom the followers of our religion refer. I have compiled all those hadiths I came across.

After this he has named numerous books and piled the narrations over tahreef.

2. Moreover on page 31 of the same book, he has quoted the comments of Muhaddith Jazayeri:

Saiyid Muhammad Jazayeri has written in the book Anwar which means the people of Imamiyah have agreed on the accuracy (authenticity) of these advantageous (mustafeedha) and continued (mutawatir) narrations which clearly imply the Quran being tampered (changed), this tampering is with Quran as well as with parts and with a’rab (vowel points) and Imamians have agreed on the attestation of these narrations.

3. On page 251 of the same Faslul Khitab, he quotes other ‘ulama as well other than muhaddith Jazayeri, saying the narrations of tahreef are mutawatir.
Certainly the narrations on tahreef are numerous even that Saiyid Ne’matullah Jazyeri has written in some of his compilations as is transmitted through them, the narrations which imply the tampering in Quran are more than 2000 (in number) and a jama’at (group) has claimed for them to be mustafeedh, for example Mufeed, researcher Damaad and ‘Allamah Majlisi etc. rather the Shaykh in Tabayaan has clearly stated that these narrations are numerous even that a group of hadith scholars has claimed that such narrations are mutawatir which would be discussed later on…

It should be known that hadiths on tahreef (of Quran) have been transmitted from those books in which our fellows trust in order to establish commands of shari’ah and to transmit traditions of Nabawiyah.

3. Afterward the author of Faslul Khitab has fulfilled his promise and in the end of the book has mentioned the names of all those hadith scholars who have referred to narrations of tahreef as mutawatir. With these names is the name of ‘Allamah Majlisi as well and these lines of his text is worth reading:

To me the narrations about tahreef in Quran are really mutawatir (continued), if these narrations are abandoned, it would discredit all our art of hadith, even that according to my knowledge, the narrations about tahreef in Quran are not less than those of the issue of Imamat, therefore if the narrations of Tahreef in Quran are not trusted, the creed of Imamat as well can’t be proven through narrations.

4. ‘Allamah Muhsin Kashi, in the preface of Tafsir Saafi, narrating (filthy) traditions of Tahreef, says on page 32 (printed in Tehran, 1375 hijri):

The meaning of all these narrations as well as the hadiths which have been transmitted with the sanad of Ahl-al-Bayt, is that the Quran which is with us is not exactly as it was descent on Muhammad sallAllahu ‘alayhe wasallam but in it something is opposite to what Allah descent and there are some changes and tampering and certainly much of its content has been removed for example the name of (Imam) ‘Ali from many places, in addition to this it is known from these narrations that the order of this Quran (arrangement of verses and chapters) is not as was agreed by God and His Messenger. This all is agreed upon by ‘Ali bin Ibrahim Qummi.

5. Great mujtahid of the last period, Molvi Dildaar ‘Ali whom shias’ great Imam, Molvi Hamid Husain calls Ayatullah fil ‘aalameen, writes in ‘Emadul Islam:

Ayatullah fil ‘aalameen i.e. Molvi Dildaar ‘Ali says, after quoting some hadiths over Tahreef (in Quran) transmitted from the leaders of creation (i.e. Imams of Ahl-al-Bayt):

The conclusion of these narrations is that there was certainly a tampering (tahreef) in this Quran which is before us, with respect to an addition of some letters (huroof) and a loss of some letters even some words and with respect to the order. In this way after believing in these narrations, there cannot be any doubt in the tampering of Quran. (after this Molvi Dildaar ‘Ali has mentioned forms of tampering which we would see later, inshaAllah)

Some Evidences (taken from Allaahuakbar.net)

1. Muhammad ibn Ya'qub al-Kulaini on the authority of Jabir that he heard Abu Ja'far saying: "Whoever claims from amongst the people that he has collected the entire Qur'an as Allah has revealed it is a liar. Only 'Ali and the Imams after him had collected it and memorized it as Allah had revealed it."

(Usul al-Kafi, Chapter that the Qur'an was not entirely collected except by the Imams, and they only have all knowledge)

2. Kulaini has narrated on the authority of Salim ibn Salamah who said: "A person recited a portion of the Qur'an to Abu 'Abdullah (Imam Ja'far), and I heard that a few words of the Qur'an which the other people did not recite. At this, Imam Ja'far told him: "Refrain from reciting this way, recite like how the common people (sunnis and shias) recite it until the appearance of the saviour (Imam Mahdi). When he appears, recite the Qur'an to its fullest. I will then reveal the manuscript which 'Ali had written. It is the same manuscript, after writing it, he presented it to the people saying: "This is the Book of Allah as was revealed upon Muhammad (S.A.W.). I have gathered it from the tablets." The people told him: "We already have a manuscript in which the entire Qur'an has been collected. We are not in need of yours." At this, 'Ali told them: "By Allah, I will never show it to you after this day. I was charged to inform you of it after I collected it so that you may recite it."

(Usul al-Kafi, Indian edition, pge 68)

3. Kulaini has again narrated on the authority of Ahmad ibn Muhammad ibn Abu Nasr who said: "Abu al-Hasan gave me a manuscript and told me to see what was written therein. I opened it, and under the verse "Those who disbelieve will not??.." were written the names of seventy ---- along with the names of their father." (Usul al-Kafi, Indian edition, pge 680)

4. Kulaini again narrates that Abu 'Abdulah said: "Jibra'il descended upon Muhammad with the following verse in this way: "O people of the Book, bring faith in what we have revealed regarding 'Ali, the magnificent light." (Ibid)

5. Some of the Shi'ahs have accused Sayyidian 'Uthman that he had destroyed the original Qur'an by burning it, and all the chapters which contained the virtues of 'Ali and the ahl al-Bait were also destroyed. From amongst these portions is the chapter of wilayat as follows: "In the name of Allah, the Most Beneficent, Most Merciful. O you who believe, bring faith on the two lights which We have revealed. They will recite My verses to you and will warn you of the punishment of a terrible day. These two lights are of each other, and I am All-Hearing All-Knowing." (Faslul Khitab fi Tahrif Kitab Rabb al-Arbab pge 180)

6. Ahmad ibn Abu Talib Tibirsi narrates on the authority of Abu Dharr al-Ghifari (R.A.): "When the Holy Prophet passed away, 'Ali gathered the Qur'an and produced it to the Emigrants (Muhajirun) and the Helpers (Ansar) as the Holy Prophet had bided him to do so. When Abu Bakr opened the first page, he found some denunciation of the Quraish tribe. At this 'Umar leapt forward and said: "O 'Ali, take it back for we are not in need of it." 'Ali took it back. Just then Zaid ibn Thabit, a prominent reciter of the Qur'an appeared, and 'Umar told him: "'Ali was here a short while back with a Qur'an which despises the Emigrants and the Helpers. I think we should compile such a Qur'an wherein all these aspects are omitted." Zaid agreed with him, but he added: "Once I have completed the Qur'an according to this method and 'Ali sees it, will your version be not invalidated?" 'Umar then asked: "What ruse should we employ then?" Zaid replied: "You know better of such ruses." At this 'Umar said: "There is no ruse but to kill 'Ali and obtain comfort from him in this way." 'Umar then thought of having him killed by Khalid ibn al-Walid, but this plan failed. When 'Umar assumed the leadership after some time, the people asked 'Ali to produce his Qur'an. 'Umar asked him: "O 'Ali, produce the Qur'an which you showed Abu Bakr so that we may agree on it." At this, 'Ali said: "This is not possible, I only showed it to Abu Bakr so that the proof may be established on you people, and so that you may not say on the day of Judgement: "We were unaware of it," "You did not produce it." The Qur'an in my possession will not be touched except by the pure, and the designated ones of my family." 'Umar asked: "Is the time known when it will be produced." Upon this 'Ali replied: "Yes, when the saviour of times emerge, it will be produced and all the people will agree to it." (Al-Ihtijaj, Najaf, pge 225. Also see Tafsir al-Safi pge 11, and Fasl al-Khitab pge 7)

7. Husain al-Nuri al-Tabarsi says: "It has been narrated from many of the Rawafid (shias) of times gone by that the present Qur'an is not the one which was revealed upon Prophet Muhammad (S.A.W.). it has been altered, and many words added on and omitted." (Faslul Khitab fi Tahrif Kitab Rabb al-Arbab pge 32) .

The Beliefs of the Shi'ites about the Present Quran (taken from Allaahuakbar.net)

Jabir reported that he heard Imam Baqir saying: 'No one can claim that he has compiled the Quran as Allah revealed except a liar. The only person to compile it and memorise it according to its revelation was Ali ibn Abi Talib and the Imams who succeeded him.

(Usole kafi 1:228)

A man said that someone was reciting the Quran in the company of Imam Ja'far. The narrator said that he heard certain verses in the recitation which were not according to the recitation of the people. Imam Ja'far told the person reciting: 'Do not recite like this. Recite as the people recite until the (promised) Mahdi arrives. When the Mahdi arrives, he will recite the Quran according to its original revelation and the Qu,ran compiled by Ali will be brought forward. (Ibid: 2.622)

Allah says in Surah Ale Imraan (32):

"Certainly Allah has chosen Adam, Noah, the family of Abraham and the family of Imraan above the (families of the) worlds."

Allamah Ali ibn Ibrahim AI-Qummi - one of the early Shi'ite commentators of the Quran said concerning this verse:

'The Imam said: 'The words: "The family of Muhammed" were also revealed along with "the family of Ale Imraan." They (referring to the Companions of the Prophet S.A.W.) removed the words "The family of Muhammad" from the original text (Al-Qummi's commentary:308). The allegation of removing the words preempts any possibility of abrogation. It is clear that the commentary is accusing the Companions of the Prophet (Sallallaahu Alayhi Wasallam) of distorting the Quran.

Allah says in Surah Taha (115):

"And We had given Adam an order before, but he forgot and We did not find any resolve in him (to disobey the order)."

Imam Ja'far is reported to have said that Allah had revealed this verse with the following words:

"We had ordered Adam before with some words about Muhammad, Ali, Fatima, Hassan, Hussain and the Imams from their offspring but he (Adam) forgot." Ja'far said: 'By Allah, these were the words which were revealed to Muhammad.' (Usul Kafi: 1:416 and the footnotes of Maqbool's translation: 637)

Allah says in Surah Yusuf (49):

"Then a year will come in which people will be given abundant help and they will press grapes." In AI-Qummi's commentary it is reported from Imam Ja'far that someone recited this verse in the presence of Ali. Ali said: 'What will they press'? Wine?' The person asked how he should read the verse. Ali replied that the verse was revealed thus: "Then a year will come in which people will he given abundant help and in which they will be given abundant rain. (Al-Qummi's commentary: 192)

The word Ya'siroon in the present Quran is in the active voice. According to this commentary it should have been read in the passive voice as Yu'saroon to alter the meaning. In the footnotes to the translation of Maqbool, it is written that this word (Ya'siroon) was changed from the passive voice to the active to suit the fancies of wine-loving khulafa (rulers). (Maqbool's translation: 479)

Allah says in Surah Muhammad (9):

"That is because they resented what Allah revealed, so Allah in turn cancelled their deeds." AI-Qummi has stated that Imam Muhammad Baqir said that Jibreel had transmitted this verse as: 'That is because they resented what Allah revealed about Ali.' But then the apostates removed Ali's name (from the Quran). (Ibid: 1011)

Allah says in Surah Waqi'ah (29):

"And the Companions of the Right Hand. What about the Companions of the Right Hand. They shall be among thornless lote-trees and under clusters of bananas."

One person recited this verse in the presence of Ali. Ali said that the word Talh is not.appropriate and should read Tal'a as in Surah Shu'araa (.........). Some enquired as why the word should not be changed. Ali replied that it was not the right time to do so because correcting the Quran would only confuse common people. He went on to say that among the Imams, only Imam Mahdi will have the right to reintroduce the Quran as it was during the time of the prophet (Sallallaahu Alayhi Wasallam). (Ibid: 1067)

Abu Mansur Ahmed Tibrisi, a prominent Shi'ite scholar of the 8th century (H), has written:

'Enumerating the distortions and omissions of this sort (from the present Quran) would become laborious and it will disclose what Taqiyyah (Shi'ite practice to conceal the 'truth' for religious purposes) requires me not to disclose: the good qualities of Allah's friends and the vices of His enemies. (AI-Ihtijaj by Tibrisi: 1:254)

Mullah Muhsin Kashani, an 11th century Shi'ite scholar comments on the above quoted statement:

'It is clear from all of these traditions and quotations from the Family of the Prophet (Sallallaahu Alayhi Wasallam) that the present Quran is not the complete Quran which was revealed to the Prophet (Sallallaahu Alayhi Wasallam). In fact, there are verses that contradict that which was revealed; verses that have been distorted and places where omissions have been made such as the names of Ali, the Family of Muhammad (Sallallaahu Alayhi Wasallam) and, on several occasions, there were the names of the hypocrites. Moreover, the present order of the Quran is not according to the preferred order of Allah and His Messenger. Ali ibn Ibrahim (a renowned commentator) also holds this opinion.' (Tafseer of Saafi: l:32).

QUR'AAN

(I) Qur'aan - The Shi'ites call the Qur'aan "Note Book of Othman." They consider the present Qur'aan as compiled by, Hazrat Abu Baker (R.A.), Hazrat Omar (R.A.) and Hazrat Othman (R.A.) whom they consider usurpers of Hazrat Ali's (R.A.) caliphate, unbelievers and renegades. (The fact is that the whole Qur'aan was revealed to the Holy Prophet Sallallahu Alayhi Wasallam who got it written on slabs of bones and stones, parchments etc. and it was memorised by many companions and recited in the presence of the Holy Prophet Sallallahu Alayhi Wasallam).

The Shia belief is that the real Qur’aan was entrusted by the Holy Prophet (Sallallahu Alayhi Wasallam) to Hazrat Ali (R.A.), but when the enemies did not believe in the same, Hazrat Ali (R.A.) concealed it and entrusted the same to his successor Imaams, and the eleventh Imaam handed it over to the twelfth Imaam - the underground and hidden Imaam. He is keeping the real Qur'aan in his custody, and when he will reappear, he will then reveal the real Qur'aan. The underground Imaam was only a child when he was entrusted with the Holy Qur'aan for safe custody.

The Shias believe that in the real Qur'aan lying with the underground Twelfth Imaam, there is a clear mention of Hazrat Ali (R.A.) and his posterity Imaamat. The present Qur'aan is abridged and the Shias per force believe the same as Qur'aan - but it is only, a stopgap belief. (vide Majalisus - Shia 147-149). (Al Balaghul- Mobin 368) (Ibid 37 Volume Two, 378, 373). (On the other hand, even European Orientalists consider the Qur'aan to be the only religious scripture in the world free from any temperance and existing in its pristine purity).
