Corruption of the Qur'an

This article examines the Islamic claim that the Qur'an is free from corruption.

Introduction[edit]

The Qur'an is claimed to be a revelation from Allah to Prophet Muhammad through the Angel Gabriel. It was revealed to Muhammad in stages, taking 23 years to reach its completion.

At no time during Muhammad's life did he ever order these alleged revelations to be compiled into a single book.[1] If Muhammad was, as he claimed, a messenger to all mankind, it is perplexing as to why he never gave thought to the preservation of his message.

His followers must solely take the credit of the Qur'an's existence today and its spreading to people beyond those which Muhammad had initially subjugated. Muslims however would argue that the Qur'an was preserved by Allah as he had promised.[2]

The Evidence from Within[edit]

We can find evidence that suggests the Qur'an was corrupted through many sources, but what is most striking is the evidence from the Qur'an itself. The Qur'an tells us "There were some among the Jews who pervert words from their proper places..."[3]

The word "pervert" in Arabic is Yuharifoon, which means "corrupt". Therefore, according to the Qur'an, al-Tahreef (corruption) is achieved through changing words from their proper places.

Has the Qur'an been subjected to such changes? Beyond a shadow of doubt, it has. If we read surah 5:3, it says "This day have I perfected your religion for you and completed My favour upon you and have chosen for you Islam as religion."[4]

This was quoted from chapter 5, and the Qur'an contains 114 chapters in total. How can the religion of Islam be completed by chapter 5, when there are 109 chapters yet to come? If it was completed in chapter 5, then there is no need for the 109 chapters ahead.

Some Muslims argue that this verse was the last verse revealed. If that is so, why then is it not placed at the conclusion? This proves that Muslims have changed the words from their right places, and according to the Qur'an, that is Tahreef (Corruption).

The first surah to be revealed was al-Alak, yet it is surah al-Fatiha which we find at the beginning of the Qur'an. Instead, Muslims have placed the first chapter to be revealed (al-Alaq), as chapter 96, towards the end of the Qur'an.

How is this not the changing of words from their right places? This is indeed 'Tahreef'. Muslims have not arranged the surahs chronologically. They took it upon themselves to organize the revelations instead of Allah completing this task himself.

Could the Qur'an have Been Preserved through Memorization?[edit]

We would say no, as Muhammad himself had forgotten portions of the Qur'an and needed his followers to remind him.[5] This led to him having a "just in time" revelation[6] claiming that some verses were to be forgotten.

What about the great memorizers of Islam from among the Salaf, maybe they had successfully memorized it? Well, that would not work as an argument. The best, and most, of the Qurra' (“reciters”) had died before its compilation.[7] Abu Bakr even knew that the Qur'an would be hard to collect[8] and that Muhammad had never ordered such an action to be taken.[1]

The Qur'an in fact was not memorized in full by the companions, and for proof of this we need only look to the words of Zaid bin Thabit, the companion who was charged with its collection.

He had stated "I started looking for the Qur'an and collecting it from (what was written on) palm-leaf stalks, thin white stones, and also from the men who knew it by heart, till I found the last verse of Surat at-Tauba (repentance) with Abi Khuzaima al-Ansari, and I did not find it with anybody other than him."[9]

Had the companions fully memorized it, why then would they look for verses in leafs and stones? Surah al-Taubah was found with one person only.

Disagreements on the Qur'an and its Burning[edit]

During the Caliphate of Uthman, he heard that many Muslims were arguing that they can recite the Qur'an better, and they had differences between them.[10]

Upon hearing this, Uthman hurriedly ordered the burning of both fragmentary manuscripts and whole copies of the Qur'an[11] and sent a message to Hafsa (one of Muhammad's wives) requesting the manuscripts she had in her possession.[12] Making a codex from what Zayd bin thabit had originally compiled,[9] he gave it to the people.

Even after the final recension of the Qur'an during Uthman's reign, disputes still came to the fore in respect to the authenticity of the text. A very good example concerns a variant reading of Surah 2.238.

The Qur'an as it stands today, reads "Maintain your prayers, particularly the middle prayer (as-salaatil wustaa), and stand before Allah in devoutness".[13]

The variant reading of this verse was given by Aisha, according to whom, in this verse it says 'Asr Prayer' (salaatiil 'asri).[14] However, according to Hafsa's Codex,[15] this was never the case.

Abdullah bin Mas'ud- Authority of the Qur'an and Best Qur'anic Teacher[edit]

Muhammad ordered Muslims to learn the Qur'an from four individuals and the first of them was Abdullah bin Mas'ud.[16] So, according to Muhammad, Ibn Mas'ud was an authority on the Qur'an.

Ibn Mas'ud swore that he knew all the surahs of the Qur'an, saying "By Allah other than Whom none has the right to be worshipped! There is no Sura revealed in Allah's Book but I know at what place it was revealed; and there is no verse revealed in Allah's Book but I know about whom it was revealed. And if I know that there is somebody who knows Allah's Book better than I, and he is at a place that camels can reach, I would go to him".[17]

That is quite a grandiose statement by Ibn Mas'ud, which we cannot disagree with. After all, according to Muhammad's words, he was one of the chosen teachers whom Muslims were to go to when they desired to learn the Qur'an.

After Muhammad's choice of Abdullah bin Mas'ud, he was followed by Salim, the freed slave of Abu Hudhaifa, Mu'adh bin Jabal and Ubai bin Ka'b.[16] What is odd is that we do not find any mention of Zayd Bin Thabit who was ultimately entrusted by Uthman with the task of collecting the Qur'an from scraps.

Ibn Mas'ud's Disagreement with Uthman[edit]

The Qur'an that Ibn Mas'ud had was known and agreed upon by many Muslims. When Uthman ordered that all codices must be destroyed and that only Zayd's codex is to be preserved, The reaction of Abdallah ibn Masud was great.

"I have not led them [the people of Kufa] astray. There is no verse in the Book of Allah that I do not know where it was revealed and why it was revealed, and if I knew anyone more learned in the Book of Allah and I could be conveyed there, I would set out to him".[18]

Referring to the authority given to Zaid bin thabit, Abdullah ibn Mas'ud said, "I recited from the messenger of Allah (saw) seventy surahs which I had perfected before Zaid ibn Thabit had embraced Islam".[19]

When Uthman ordered the destruction of Ibn Mas'ud's codex, Ibn Mas'ud gave a sermon in Kufa and said "The people have been guilty of deceit in the reading of the Qur'an. I like it better to read according to the recitation of him (Prophet) whom I love more than that of Zayd Ibn Thabit. By Him besides Whom there is no god! I learnt more than seventy surahs from the lips of the Apostle of Allah, may Allah bless him, while Zayd Ibn Thabit was a youth, having two locks and playing with the youth".[20]

Zaid bin thabit was in no place to be a rival to the great scholar and teacher Ibn Mas'ud, and such sermons by him are devastating to the history of Islam and to the authenticity of the Qur'an.

What did Ibn Mas'ud have in his Qur'an that Uthman did not?[edit]

Ibn Mas'ud's Qur'anic text omitted surah al-Fatiha and the mu'awwithatayni (surahs 113 and 114).[21]

When we come to the rest of the Qur'an, we find that there were numerous differences of reading between the texts of Zaid and Ibn Mas'ud. The records in Ibn Abu Dawud's Kitab al-Masahif fill up no less than nineteen pages[22] and, from all the sources available, one can trace no less than 101 variants in the Suratul-Baqarah alone.

We will provide you with the mention of just a few of the differences here in illustration of the nature of the variations between the texts:

Surah 2:275 begins with the words Allathiina yaakuluunar-ribaa laa yaquumuuna, meaning "those who devour usury will not stand". Ibn Mas'ud's text had the same introduction but after the last word there was added the expression yawmal qiyaamati, that is, they would not be able to stand on the "Day of Resurrection".

The variant is mentioned in Abu Ubaid's Kitab Fadhail al-Qur'an.[23] The variant was also recorded in the codex of Talha ibn Musarrif, a secondary codex dependent on Ibn Mas'ud's text, Taiha likewise being based at Kufa in Iraq where Ibn Mas'ud was based as governor and where his codex was widely followed.[24]

Surah 5:91, in the standard text, contains the exhortation fasiyaamu thalaathati ayyaamin, meaning "fast for three days". Ibn Mas'ud's text had, after the last word, the adjective mutataabi'aatin, meaning three "successive" days.

The variant derives from at-Tabari[25] and was also mentioned by Abu Ubaid. This variant reading was, significantly, found in Ubayy ibn Ka'b's text as well[26] and in the texts of Ibn Abbas[27] and Ibn Mas'ud's pupil Ar-Rabi ibn Khuthaim.[28]

The Qur'an we have today was rejected by Ibn Masud, whom the prophet of Islam himself approved of. This tells us that the Qur'an we have is not the word of Allah.

Ubay bin Ka'b[edit]

Ubay ibn Ka'b, one of the four which were singled-out by Muhammad,[16] was considered the best reciter of the Qur'an.[29] He was known as Sayidul Qura' (The Master of Reciters). Umar the Caliph also agreed that Ubay was the best reciter.[30]

Ubay agreed with Ibn Mas'ud and disagreed with Zayd on the following:

1. For the standard reading wa yush-hidullaaha in Surah 2:204 he read wa yastash-hidullaaha.[31]
2. He omitted the words in khiftum from Surah 4:101.[32]
3. He read mutathab-thibiina for muthabthabiina in Surah 4:143.[33]

There are a number of cases where whole clauses differed in his text. In Surah 5:48, where the standard text reads wa katabnaa 'alayhim fiiha, meaning "and We inscribed therein for them (the Jews)", the reading of Ubayy ibn Ka'b was wa anzalallaahu alaa banii Isra'iila fiiha, meaning "and Allah sent down therein to the Children of Israel."[34]

From Abu Ubaid we find that, whereas Surah 17:16 in the standard text reads amarnaa mutrafiihaa fafasaquu, Ubay read this clause ba'athnaa akaabira mujri-miihaa fdmakaruu.[35]

We know that, whereas Ibn Mas'ud omitted two surahs (113 and 114) from his codex, Ubayy included two extra surahs, al-Hafd (the Haste)[36] and al-Khal' (the Separation).[37][38]

What is Missing from the Qur'an[edit]

Surah at-Tawba was originally equal to the length of al-Baqara, losing about 157 verses.[39]

Abu Musa al-Ash'ari, one of the early authorities on the Qur'an text and a companion of Muhammad, claimed a surah which resembled at-Tawba in length and severity was forgotten and lost.[40]

According to Abu Waqid al-Laithii, Muhammad recited to him the verse on "the greed of man" which read, "We sent down wealth to maintain prayer and deeds of charity, and if the son of Adam had a valley he would leave it in search for another like it and, if he got another like it, he would press on for a third, and nothing would satisfy the stomach of the son of Adam but dust, yet Allah is relenting towards those who relent."[41] This verse is not found in today's Qur'an.

The lost verse of Rajm (stoning) which read "The fornicators among the married men (ash-shaikh) and married women (ash-shaikhah), stone them as an exemplary punishment from Allah, and Allah is Mighty and Wise,"[42] was originally found in Surah al-Ahzab[43].

This verse, along with verses regarding adult suckling, were written on a piece of paper and were lost when a goat ate them.[44] The loss of the stoning verse is confirmed by Caliph Umar in sahih hadith.[45]

Alhajjaj changes the Uthmanic Qur'an[edit]

The text we have today is not even Uthman's Revised Version of the Qur'an, but it incorporates changes by Al-Hajjaj Ibn Yusuf Al-Thakafi.

Al-Hajjaj Ibn Yusuf Al-Thakafi, who lived in the years AD 660-714, was a teacher of the Arabic language in the city of Taif. Then he joined the military and became the most powerful person during the reign of Caliph Abd al-Malik Ibn Marawan and after him his son al-Waleed Ibn Abd al-Malik. Because Al-Hajjaj taught Arabic, he gave himself the liberty to change several words of Caliph Uthman's Qur'an, which is an indication that he did not believe that the Qur'an was verbally inspired or was inscribed in a "tablet preserved."

For brevity's sake we will only mention a few of these changes:

1. In Surah Yunus 10:22, he changed the word yanshorokom, which means "spread you," to yousayerokom, which means "makes you to go on."

2. In Surah Ash-Shuara 26:116, he changed the word Al-Mukhrageen, which means "the cast out," to Al-Margoomeen, which means "those who are to be stoned [to death]."

3. In Surah Ash-Shuara 26:167, he changed the word Min Al-Margoomeen, which means "those who are to be stoned to death," to Al-Mukhrageen, which means "those who will assuredly be cast out."

4. In Surah Muhammad 47:15, he changed the word yasen, which is poor Arabic to Asen, which means "unpolluted."

5. In Surah al-Hadid 57:7, he changed the word wataqu, which means "feared Allah," to Wa-anfaqu, which means "spend in charity."

If you read Qur'anic Tafsirs such as al-Jalalayn and others on these verses, you will notice that they will say that there are other readings of these words, proving that there was corruption.

Differences in the Hafs and Warsh Texts[edit]

Apart from other earlier variant text, there are two different texts of the Qur'an currently in print, named after their respective 2nd-century transmitters Hafs (from Kufa) and Warsh (from Medina).

The Hafs text is the more common and used in most areas of the Islamic world. Warsh is used mainly in West and North-West Africa as well as by the Zaydiya in Yemen. Here are some of the differences:

Surah Hafs Warsh Notes
2:132 wawassa wa'awsa Al-Dani mentions Abu `Ubayd saw wa'awsa

in the imam, the mushaf `Uthman

3:133 wasari'u sari'u
5:54 yartadda yartadid Al-Dani quotes Abu `Ubayd saw yartadid in the imam
3:81 ataytukum ataynakum
2:259 nunshizuha nunshiruha
2:140 taquluna yaquluna

Diacritical Marks and Grammatical Mistakes[edit]

The Qur'an was written without diacritical marks. At the time of Muhammad, Arabic orthography was yet to develop into what we have known for centuries.

For the early interpretors who added diacritical marks, to read the Qur'an as it was originally written, would lead the reader to interpret and choose for themselves from the many possible meanings available.

Muslims began using diacritical marks because reading "errors" began to appear,[46] and the differences this created had led to differences in Islamic law.[47]

The following are just a few examples from among many grammatical mistakes which show that the Qur'an is not flawless.

1. Sabi'een or Sabi'oon, one must be wrong (5:69, 22:17)

2. Butunihi is a mistake in 16:66. It must be Butuniha, because it is referring to the plural (cattle).

3. Kon fayakoon, meaning "be and it is", must be kon fakana, meaning "be and he was" in 3:59, because it refers to the past not present.

Corruption of Previous Scriptures[edit]

Many Muslims erroneously believe that the Qur'an claims the corruption of previous scriptures. However with this erroneous belief comes a new set of problems.

The Qur'an says in 15:9, "We have revealed the dhikr (reminder) and we surely will preserve it," but which "reminder" is Allah referring to, and who decided it only applied to Qur'anic text?

The Taurat and Injil are also referred to as dhikr in 21:48, 21:7, and 40:53-54. So if Allah could not protect these dhikrs as he promised in 15:9, how can we expect him to protect the last dhikr?

Allah said he will preserve the dhikr, either he preserves all the dhikr (Taurat, Injil, and Qur'an) or None.

Conclusion[edit]

What have we learnt here? We have learnt that some verses are missing, some readings are different, and the very best scholars and reciters of Islam, whom Muhammad himself had approved of, rejected the Qur'an of Uthman.

What are we left with? We are left with a very human text, as prone to corruption as any other medieval text, and Muslims who deny this are left holding an untenable position.
