Qur’an preserved to the letter and sound.
Evidence through Disjointed letters.
Evidence of sound oral recitation or qira’at.

Alhuroof almuqatti’a or disjointed letters occurs at the beginning of some surahs. Had there been an absence of oral recitation from the Prophet ﷺ and his companions, these letters or their combinations could have been read a large number of ways in the early Qur’ans

...almost devoid of vowel marks and diacritics. These are not words with a meaning, they are just functional letters.

Example 1) الم
Occurs in 6 surahs.
All read as Alif. Lam. Meem. None read as alam. The same graphical form occurs in
الم تر...
الم نشرح...

All read as alam.

Example 2) ىس
All read as يس Ya Seen.

None read in other letter combinations with numerable vowel permutations (390 at least)

Can be ب ت ث ن ي with س or ش
Combined as
بس
بش
تس
تش
ثس
ثش
نس
نش
يش
If we take one form بس , we have the following readable permutations.

بَسَ
بُسُ
بِسِ
بَسِ
بُسِ
بَسُ
بِسُ
بِسَ
بُسَ
بَسْ

This is evidence enough to conclude:
1. Qira’at are not whimsical readings or mistakes.
2. They did not originate because of defective script in the Qur’an manuscripts.
3. There must be an oral tradition restricting these readings.
4. Islamic traditions says precisely that.

5. There are recitals transmitted from the Prophet ﷺ.
6. Prophet ﷺ recited the same Qur’an in multiform readings.
7. Muslims are agreed upon on the 10 authentic qira’at of the Qur’an.
8. They are authentically preserved even to the letters and sounds.
