Versions of the Quran
The claim that the Quran exists in 10 Qirāʾāt or 7 Ahruf is unfounded and contradicts the Quran itself. The Quran is singular in its revelation and preserved in a clear Arabic language.
The Revelation of the Quran
نَزَلَ بِهِ ٱلرُّوحُ ٱلۡأَمِينُ * عَلَىٰ قَلۡبِكَ لِتَكُونَ مِنَ ٱلۡمُنذِرِينَ * بِلِسَانٍ عَرَبِيّٖ مُّبِينٖ
Nazzala bihi ar-roohu al-ameen, 'ala qalbika litakoona minal munthireen, bilisaanin 'arabiyyin mubeen.
The Trustworthy Ruh brought it down unto your heart so that you would be one of the warners, in a clear Arabic tongue.
(26:193-195)
This verse explicitly states the Quran was revealed in a single clear Arabic language, not in multiple versions or dialects.
Quran Revealed as a Single Entity
وَإِذَا تُتۡلَىٰ عَلَيۡهِمۡ ءَايَٰتُنَا بَيِّنَٰتٞ قَالَ ٱلَّذِينَ لَا يَرۡجُونَ لِقَآءَنَا ٱئۡتِ بِقُرۡءَانٍ غَيۡرِ هَٰذَآ أَوۡ بَدِّلۡهُۗ قُلۡ مَا يَكُونُ لِيٓ أَنۡ أُبَدِّلَهُۥ مِن تِلۡقَآئِ نَفۡسِيٓۖ إِنۡ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَيَّۖ إِنِّيٓ أَخَافُ إِنۡ عَصَيۡتُ رَبِّي عَذَابَ يَوۡمٍ عَظِيمٖ
Wa īzā tutlā 'alayhim āyātunā bayyinātin qālalladhīna lā yarjūna liqā'ānā i'ti biqur'ānin ghayri hādhā aw baddilhu qul mā yakūnu lī an ubaddilahu min tilqā'ī nafsī in attabi'u illā mā yūḥā ilayya innī akhāfu in 'asaytu rabbī 'adhāba yawmin 'aẓīm.
When Our clear revelations are recited to them, those who do not seek the meeting with Us say, 'Bring a Quran other than this or replace it.' Say, 'It is not for me to replace it of my own accord. I only follow what is revealed to me. I fear if I disobey my Lord, the punishment of a great Day.'
(10:15)
This verse affirms the Quran has no alternative versions. If variations existed, the Prophet Muhammad would have presented them when requested, but he categorically denied their existence.
True Recitation of the Quran
ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَتۡلُونَهُۥ حَقَّ تِلَاوَتِهِۦٓۚ أُوْلَٰٓئِكَ يُؤۡمِنُونَ بِهِۦۗ وَمَن يَكۡفُرۡ بِهِۦ فَأُوْلَٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ
Alladhīna ātaināhumul-kitāba yatlūnahū ḥaqqa tilāwatih; ulā'ika yu'minūna bihi; wamanyakfur bihi fa ulā'ika humul-khāsiroon.
Those whom We have given the Scripture and they recite it as per its correct recitation; they are the ones who believe in it. As for those who disbelieve in it, they are indeed the losers.
(2:121)
God refers to "its true recitation" in the singular form, indicating that the Quran’s recitation is one, not varied into multiple styles or versions.
Conclusion
The Quran was revealed in a clear Arabic language as a single, unified text. The notion of multiple versions or varying recitations is an unfounded claim. God explicitly denies such fabrications and affirms the Quran's clarity, consistency, and divine preservation. Believers are advised to seek guidance solely from the Quran and reject distortions or innovations.
