Quran during Muhammed times is different than the one we have today, so shall it be called corrupted

…
1) During the time of Muhammed, some of the Quran had been written by his disciples when Muhammed used to recite them, they were written using early Arabic ancient script (no pointing and no vowel marks) on papyrus and leather fabric, however, some versus of Quran were not written at all but his disciples were memorizing them.
2) After Muhammed death Abu-Bakr ordered all versus of Quran to be written.
3) During Uthman time (after around 14 years of Muhammed death), Uthman burnt all versions of Quran and wrote his own version:

4) During the 5th Umayyad Caliph (after around 70 years of Muhammed death), pointing and vowel marks were added to the original text:

5) Authentic hadiths:
***Sahih Muslim, Book 017, Number 4194:
***** Sahih Bukhari, Volume 8, Book 82, Number 817:
**A particular verse of the stoning punishment for stoning (male cleric) & (female cleric) was revealed to Muhammad, but now it’s not found in Quran.

6) Yemen’s manuscript:
"Puin is not alone in his enthusiasm. “The impact of the Yemeni manuscripts is still to be felt,” says Andrew Rippin, a professor of religious studies at the University of Calgary, who is at the forefront of Koranic studies today. "Their variant readings and verse orders are all very significant. Everybody agrees on that. These manuscripts say that the early history of the Koranic text is much more of an open question than many have suspected: the text was less stable, and therefore had less authority, than has always been claimed."
