Muslims believe that Allah has already promised to protect the Quran from the change and error that happened to earlier holy texts. As Allah (SWT) has stated in the holy book;
“Indeed, it is We who sent down the Quran and indeed, We will be its guardian.”
(Surat al-Hijr, 15:9)
This verse is one of the sole and most important proofs to all mankind and to Muslims in particular that the Quran will remain unaltered and unchanged for all time for Allah (SWT) Himself is guarding it. But it must be noted that there were and there will always remain people especially the Non-Muslims who simply do not accept the authenticity of the Quran to begin with nor will they ever take this verse as the proof they can accept on the authenticity of the Quran for it is a part of the Quran itself and this is the point where the academic discussion on the authenticity of the Quran began. The Quran was not revealed to Prophet Muhammad (SAW) completely at the same time; rather it was slowly revealed over the course of 23 years in the cities of Mecca and Medina. As the Quran began to be revealed, Prophet Muhammad (SAW) assigned many of his companions the work of recording the Quran as scribes and it was their job to write and record every verse as soon as it was revealed. For the most part, new verses would be written on scraps of bone, hide, or parchment, since paper had not yet been imported from different parts of the world. One thing of note is that Prophet Muhammad (SAW) would have his companions who were working as scribes of the Quran to read the verse back to him after they had written it down for this allowed the Prophet Muhammad (SAW) to make sure there were no errors and this was the first form of memorizing the Quran.
