Peace humble guest,
Sorry bro, if you learn anything from me, it's that the text of the Qur'an we have today are the exact words uttered by the Prophet Muhammad (pbuh) as they were revealed to him.
Not so, but it's lovely conjecture.
Your comparison of the Qur'an manuscripts to the Biblical Manuscripts is skewed. The Qur'an wasn't written hundreds of years after the death of the Prophet Muhammad (pbuh), unlike the gospels with respect to Jesus (pbuh).
Try a few decades, if not just one or two decades. NOT CENTURIES!!!
Second of all, the mechanism of transmissio of the Qur'an proves that the Qur'an has not changed since it was revealed. The same can't even remotely be said about the Bible, in fact, it can't even be ascertained that the full manuscripts post Nicaea match the gospels as they were written, even if they were drafted years after Jesus (pbuh) ascended.
Nice you like talking, but I want to see proof from a NON-ISLAMIC site of an existing Quran that existed before 750 AD. I will not trust your biased sites. What museum is it in currently? Why has no one heard of it? What years is it dated from?
