[Ali Imran]

That is untrue 

Bart Ehrman wrote that the Birmingham manuscript is similar to, but not identical to, the modern Quran, noting differences in verse divisions, word forms, and diacritical markings. While the variations don't significantly change the meaning, they show that early Quranic texts, like the Birmingham manuscript, weren't always in the exact final form found in Uthmanic codices.

The style of writing and how they spelled the words without diacritical markings wasn't standardized at the time the person wrote it. 

But remember, the Quran is a recitation. How it is recited is 100% identical. I've been telling you that since the beginning.
