Allah stated in the verses that the Qur'an is unchangeable:
...THERE IS NO CHANGING THE WORDS OF Allah... (Surat al-An'am, 34)
The Words of your Lord are perfect in truthfulness and justice. NO ONE
CAN CHANGE HIS WORDS. He is the All-Hearing, the All-Knowing. (Surat
al-An'am, 115)
IT IS WE WHO HAVE SENT DOWN THE REMINDER AND WE WHO WILL PRESERVE IT.
(Surat al-Hijr,9)
It is truly a noble Qur'an ina WELL PROTECTED Book. (Surat al-Waqi'a, 77-78)
FALSEHOOD CAN NOT REACH IT FROM BEFORE IT OR BEHIND IT – it is a
revelation from One Who is All-Wise, Praiseworthy. (Surah Fussilat,
42)
As our Lord reveals in the verses above the Qur'an will remain
unchanged. The Qur'an has not survived to our day merely in written
form. In the time of our Prophet (saas) there were hafidhs learning
the Qur'an by heart. Consequently the Qur'an with vowel points in our
day was prepared ina way convenient to the memorization of the Hafidhs
of the time. The Qur'an memorized by the Hafidhs of the time of our
our Prophet (saas) is exactly the same as the Qur'an in our day
insha'Allah.
