Taḥrīf (Arabic: تحريف‎, "distortion, alteration") is an Arabic term used by Muslims for the alterations which Islamic tradition claims Jews and Christians have made to the revealed books, specifically those that make up the Tawrat (or Torah), Zabur (possibly Psalms) and Injil (or Gospel). Traditional Muslim scholars, based on Quranic and other traditions, maintain that Jews and Christians have changed the word of God.


It is the consensus of the Shi'a scholars that there is no distortion in the Qur'an. You can read more about this topic in the article below that gives references to the statements of a variety of scholars.


A famous scholar Ayatullah Sayyid Abu'l Qasim al-Khu'i has a detailed discussion around this topic in his book that you can also go through for a more in-depth treatment of this subject.

Not at all.

All prominent Shia Scholars believe that Quran is intact and never been distorted.
Shia enemies put false allegations on us including in this matter. If they read our books properly, they will see that our faith is that Quran is intact. Sunni books have narrations from Omar that Sura al-Ahzaab was like Sura Baqarah, and from Ayisha that a Quranic chapter was eaten by a pet. These Sunni narrations and any similar narration are rejected by us because we believe that Allah (SWT) has promised to save and protect Quran from any discretion. (Sura Al-Hijr, verse 9).

We do believe that many persons tried and still trying to twist the meaning of some Quranic verses to make it in accordance to their wrong claims, but Qurani'c words are intact.

Shia scholars have written books on this subject confirming our faith in the intact Quran.

Quran is complete, intact and unchanged. This is the faith of leading Shia scholars including Ayatullah Sistani, Ayatulla Al-Khoei, Shaikh Al-Sadouq, Shaikh Al-Toosi, Sayyed Al-Murtadha, Shaikh Al-Mufeed, Shaikh Al-Tabrasi, Shaikh Kaashif Al-Ghitaa' and thousand of Shia scholars.

There are some Sunni narrations from Umar and Ayisha that Qur'an which is available in our hands is not complete (Saheeh Muslim 1050, Musnad Ahmad 5:132, Al-Mustadrak 4:359, Al-Kashshaaf 3:518 etc), with few weak narrations in few Shia books,  but there is no values for such narrations. Our authentic evidence from Ahlul Bayt (AS) is unchallengeable that Qur'an is complete and intact.

The authentic Hadeeths from the Holy Prophet (SAWA) and his holy
progeny, the Ahlul Bayt (AS) are confirmed through a very strict
procedure of checking every narrator and every narration which means
that the scholars check every narrator whether he is trustworthy or
not and up to what extent he is trustworthy according what has been mentioned about him in the books of Rijaal. If all the narrators are
trustworthy then the Hadeeth will be taken as authentic. We also study
the content and the text of the Hadeeth which should not contradict
any Qur’anic verse or any other authentic Hadeeth. By this very strict
procedure our scholars are sure that no unauthentic Hadeeth can be
taken as authentic. Now the question of whether all the authentic
Hadeeth are available or not, the answer is that all the authentic
Hadeeths are with infallible Ahlul Bayt (AS). The Imam (AS) of every
time is the authority and he has all the knowledge about every Hadeeth
from the Holy Prophet (SAWA) and the Ahlul Bayt (AS). We cannot say
now that our knowledge or all our scholars’ knowledge today has all
the Hadeeths but for sure, our Imam, Imam al-Mahdi (ATFS) has all that
knowledge and he is guarding and supervising and supporting the
followers of Ahlul Bay (AS) and guiding the scholars to the real
knowledge of Islam.

Thank you for your question. There certainly was corruption of the hadith from the Prophet (saw) and Imams (as) even during their lifetimes and so at times the companions of the Imams (as) would check hadith that they did not recognise with the Imams themselves. Since the time of the ghayba one of the most important concerns of scholarship is to deal with the corpus of hadith and define benchmarks for deciphering authentic traditions from less authentic ones. There are a number of methodologies for doing that, some of which are quite technical but are discussed in the sciences of usul, hadith and rijal.

May you always be successful 


Additionally, it does not make sense to directly compare the process of compilation of the Bible and the Qur'an because the two scriptures are quite different structurally and in terms of the historical circumstances surrounding them.

The Qur'an is much newer than the Bible, much shorter than the Bible, emerged in one region and in a short span of time. There has never been any question of what portions of the Qur'an to consider canonical. It was also all in a single language and dialect. Stylistically, the Qur'an is internally consistent indicating it is the work of a single author and does not have interpolations (whether or not one considers that author to be God, it still has a single "voice"). While, at the time of the Prophet, Mecca and Medina did not have sophisticated means of producing books, it was not long before advances in those areas, such as the use of paper, came to the Islamic world; and, in fact, it was through the Islamic world that some of these technologies were transferred to Europe. 

In contrast, the compilation of the Bible is much more complicated. The scriptures are much older, span a broader length of time, and there is a lot more complexity with respect to how it came to be a single text. (There are numerous works on this subject available.) It becomes even more complicated if one considers both the New and the Old Testaments. It is not as if someone 2000+ years ago held out a book (or, rather, a scroll) called "The Bible" that is exactly the same as you find today; there was a process. 

So, from a purely historical perspective, there are very different circumstances surrounding the compilation of what today we know as the Bible and the Qur'an, and the nature of the two books is also quite different. Therefore, it is not a one-to-one comparison and it is best to look at the compilation of each scripture separately and consider the validity or authenticity of each one separately. 

Quran is the only Holy text which is completely intact, unlike Torah and Bible which have been distorted and changed into many different versions.

There is possibility at of misquoting the prophet Muhammad (SAWA) while writing the Quran as the Prophet and the writer (Imam Ali) both are Infallible supported by Allah (SWT) and His Angles. Allah (SWT) has promised to keep the Quran intact ( Verily, We Have sent the Thikr (Quran) and We will be guarding it (from corruption))(انا نحن نزلنا الذكر وانا له لحافظون )(Sura 15, verse 9)

The Prophet (SAWA) has recited the Quran and supervised writing it. No question at all of any error in writing the Quran as all the Infallible Imams read the Quran in the same way which confirms that there is no error whatsoever.

The fact of the purity of Quran is admitted even by the enemies who tried every thing to harm Quran but could not as Quran is protected by Allah (SW) and no one or power can make any change in Quran as it's enemies tried and failed.

Bismihi Ta'ala

This indeed is a sad issue that seems to never be solved. The earliest of Shi'ah scholars have addressed this in detail, establishing the completeness and perfection of the Quran, being the everlasting miracle of Islam. 

Books have been written, detailed extensive research has been made, and statements so ever frequently given, all explaining the position of Shi'ah Muslims regarding the holy Quran. 

However, with such abundant sources openly available for all to read, we see that some Sunnis persist on accepting this myth and want nothing to do with any of the solid evidence presented against it. 

The cliche referencing of Kitab Ali (a.s.) is brought up, or Mashaf Fatimah (a.s.), even though it has nothing to do with the holy Quran. 

If only someone could dig up this 'different Quran' Shi'ahs supposedly believe in. 

Do these accusations come from ignorance, or is it just malice intent fueled with hatred. 

In brief:

1. Twelver Shi'ahs believe the very Quran that is with us all today is the only and only Quran all Muslims believe in and accept. 

2. This Quran is complete, and perfect, in every form and way, with no surah or verse missing, and there is no extra surah or verse added to it. 

3. If, for argument sake, there is a Shi'ah scholar who has a view that the Quran is incomplete, or any other view of this sort, it is their view, and it does not represent the belief of the Shi'ah Creed. It is far from genuine and fair to use the singular views of one or two scholars and generalise it to be the foundational belief of the whole Shi'ah creed. 

4. If there are narrations that elude to certain surahs/verses added, or taken away, then they are rejected and not accepted.

5. There are numerous examples of this that exists in Sunni sources, like the goat eating parts of a Quran that was forever lost. However, Shi'ah Muslims have never used this to accuse Sunni Muslims of such baseless accusations. 

 It is very important to be truthful to ourselves and avoid biased or baseless information.
