The discovery of a Qur’anic manuscript in the University of Birmingham has made headlines worldwide as it is thought to be one the oldest anywhere in the world.
Radiocarbon testing of the manuscript, which is written in the Hijazi script dates it between 568 and 645 AD (24AH) and there is a possibility it was written by a companion of the Prophet Muhammad (peace and blessings be upon him). Though the Qur’an was transmitted orally the Prophet instructed some companions to write it down on parchments leaves. Islam’s third Caliph, Uthman (may Allah be pleased with him) was the first to compile the whole Qur’an into one canonical corpus.
So how does it compare to the Qur’an of today? Below is a comparison of a part of the manuscript (the beginning few verses of Surah Taha):

The above graphic shows that they are identical. No words or letters are out of place. Muslims consider the Qur’an to be the word of God and hold it to be a living miracle. Its preservation is mentioned in the the fifteenth chapter:

Whilst there maybe different dialects, the meaning of the Quran hasn't changed a single bit not this day unlike the Bible.
