There are two verses named Surah of Wilaya and Nurayn that are claimed to be included in the Qur'an.

This is a sub-article to Translation of the Qur'an. By first printing date 600s Salman the Persian The study of the origins and development of the Qur’an can be said to fall into two major schools of thought the first being a Traditionalist Muslim view and The Meccan suras are the chronologically earlier Suras of the Qur'an that were revealed at Mecca. The Medinan suras of the Qur'an are those Suras which were revealed at Medina, after Muhammad 's hijra from Mecca, when the Tafsir ( Arabic: تفسير, tafsīr, "interpretation" is the Arabic word for Exegesis Some of the Qur'anic verses are said to be revealed pertaining to some specific person Islamic Justice, truth-telling various virtues and sins the prohibition of Perjury in the Qur'an are repeated many times Justice Asbāb al-nuzūl اسباب النزول, an Arabic term meaning "occasions/circumstances of revelation" is a secondary genre of Qur'ānic Exegesis Naskh (نسخ is an Arabic language word usually translated as " abrogation " it shares the same root as the words appearing The Qur'an, the central religious text of Islam, contains references to over fifty people also found in the Bible, typically in the same or similar Tahrif ( Arabic: ar تحريف "corruption forgery" the stem-II verbal noun of the consonantal root, "to make oblique" Bakkah (بكة is a place mentioned in Surah 396 of the Qur'an. Muqatta`at (Arabic ar مقطعات,are unique letter combinations that begin certain chapters of the Quran. An esoteric interpretation of the Qur'an is an Interpretation of the Qur’an which includes attribution of Esoteric or mystic meanings to the Qur'an and Sunnah is an often quoted Islamic term regarding the sources of Islam Qur'anic literalism is the belief that the verses of the Qur'an should be taken at their apparent meaning rather than employing any sort of interpretation Muslims consider the Qur'an, the holy book of Islam, as the word of God and a Miracle. The relation between Qur'an and science is a strong relation in the Islamic thought This article is about female figures that appear in the Qur'an This is a sub-article to Shī‘a Islam and the Qur'an The Shī‘a view of the Qur'an has some differences from the Sunni view but it must Muslims believe that the Qur'an is the literal word of God as recited to Muhammad through the angel Gabriel. Qur'an desecration is defined as insulting the Qur'an, by defiling or defacing it Satanic Verses is an expression coined by the historian Sir William Muir in reference to a few verses delivered by Muhammad as part of the Qur'an Tanzil and Inzal, or "to send down" ( Arabic تنزيل refers to the act of descent of the pre-existing Qur'an through different Realms The "Qisas Al-Anbiya" (قصص الأنبياء or Stories of the Prophets refers to various collections of tales adapted from the Quran. Beit Al Qur'an (بيت القرآن means House of Qur'an in Arabic. The Qur’an ( القرآن, literally "the recitation" also sometimes transliterated as Qur’ān, Koran, Alcoran The fabrication of these verses has been considered by most scholars to be one of too many attempts by Sunnis to discredit Shi'a Muslims.
Neither Shi'a nor Sunni Muslim believe those surahs are included in the Qur'an, but some have claimed that the Shi'a do indeed believe those surahs to be an authentic part of the Qur'an and include them therein (in what has been dubbed the Shi'a Quran). Arabic (ar الْعَرَبيّة (informally ar عَرَبيْ) in terms of the number of speakers is the largest living member of the Semitic language Wali (Arabic ولي, plural Awliya ' أولياء) is an Arabic word meaning trusted one or friend generally denoting Arabic (ar الْعَرَبيّة (informally ar عَرَبيْ) in terms of the number of speakers is the largest living member of the Semitic language However, many Shi'a dismiss this as unfounded accusations aimed at accusing Shi'as of believing in the corruption of the Qur'an. No copy of the Quran exists with the addition of these two surahs and there is no mention of them found in any of the earliest codices of the Quran and Hadith. A codex ( Latin for block of wood, Book; plural codices) is a book in the format used for modern books with separate pages normally Hadith ( ar الحديث, pl aḥadīth; lit. "narrative" are oral Traditions relating to the words and deeds of the Islamic The author of text on the other hand is said to be have been a Parsi according to some academics.  On the other hand, M. Momen states that:
Western Academics such as von Grunebaum view the text as a clear forgery, although many of them haven't subscribed to the idea that the text was indeed a forgery made by a Zoroastrian and not a Shia. Zoroastrianism (ˌzɔroʊˈæstriəˌnɪzəm is the religion and philosophy based on the teachings 
These surahs have also been used in argument against Muslims by Christian apologetics to prove that the Qur'an has been altered, although many such apologetics have switched their stance from "this proves the Quran was altered" to "this proves that others can bring verses similar to the Quran. " St. Clare Tisdal writes on the matter though, essentially saying that both of these claims are erroneous:
These are the qoutations of some of the most authentic Shi'a scholars: Shaikh Saduq:
"Our belief is that the Qur’an is what is between the two covers and it is what is in people’s hands, nothing more. TemplateInfobox Muslim scholars --> Al-Shaykh al-Saduq is the title given to Abu Ja'far Muhammad ibn 'Ali ibn Babawaih al-Qummi Whosoever attributes to us that we say rather than this is a liar. "
"The knowledge of authentic transmission of the Qur’an is like the knowledge of great countries and events, prominent accidents, famous books and written Arabic poetry for care is intensified and causes are available to properly transmit and guard it, and it reached such an extent that nothing else has ever reached. The Qur’an was, during the lifetime of Allah’s Messenger (peace be upon him), compiled and arranged until the Prophet (peace be upon him) assigned a group of Companions (Sahaba) to memorize it. It was displayed and recited before the Prophet (peace be upon him) and some Companions as Abdullah Ibn Mas’ood and Ubai Ibn Ka’b recited the whole Qur’an many times before the Prophet (peace be upon him). All this indicates that it was compiled and arranged, neither amputated nor scattered ……. Who disagreed among the Imamiyyah and Al-Hashawiyyah (two Shi’ite sects) are not to be considered for disagreement is attributed to some traditionists who related weak reports whom they believed to be true. See also Shi'a Islam Twelver Shi'ism ( ar اثنا عشرية Ithnāˤashariyyah) is the largest branch of Shi'a branch of Islam However, such reports cannot refute what is already known and agreed upon its authenticity.
Shaikh Tusi or Sheikh-ut-Ta’fa (i. TemplateInfobox Muslim scholars --> Shaykh Tusi ( شیخ طوسی) full name Abu Jafar Muhammad Ibn Hassan e. , Authority of the Sect):
"Talking about it being increased or decreased is unacceptable because increasing is agreed upon its falsehood. As for decreasing, different Muslim sects are apparently against it and this matches the authentic belief of our sect and was affirmed by Al-Murtada (may Allah be pleased with him). This is explicit in various reports, however, some reports were related about decreasing parts of it and moving parts from place to place, but they are loner reports and do not indicate decisive knowledge. So, it prior to ignore them and quit being preoccupied with them because they cannot be interpreted. Even if they were authentic, it would not be against what is between the two covers for its authenticity is well known and none among the Ummah objects to or rejects it. Our reports agree upon reading it, holding by it and displaying any disagreement in branches before it, whatever agrees with it is accepted and whatever disagrees is rejected. An irrefutable tradition is reported on authority of the Prophet (peace be upon him) that he says: “I’m leaving in you the two weights (Ath-Thuqlain) by whom if you hold by, you will never be lost: Allah’s Book and my family, the inhabitants of my house. They will never separate till they join me in the Hawd”. This indicates that it is present every time because he cannot command us to hold by it if it is corrupted"
However, all the Qur'ans published in all the Shi'a countries such as Iran are the same as those published in Sunni countries. Shi’ites recite the Qur’an according to the Qira’t of Hafs on authority of ‘Asim which is the prevalent Qira’t in the Islamic world.
