Yes, it is true that muslims back in the early years made great attempts to memorise the quran however all this is irrelevant since we have hard evidence that the oldest quran is different to the current quran.
All this stuff about how the early followers would have memorised things is just opinion. The actual hard evidence we have is the only thing that matters and the actual hard evidence says that the quran has changed.
This isn't just my opinion, I'm just stating what the evidence seems to be saying. The western scholar who studied the Yemen manuscripts hasn't published his final report yet but he has published some articles in Germany. According to
this page he says:
Apparently, the earliest versions of the quran were written without vowels and diacritical marks (accents over letters). The diacritical marks were added later when the compilers of the quran wanted to make it clear what their understanding of the quran was. This system is open to abuse. As
this page points out:
So, the quran HAS changed whether you like it or not. That's a simple fact. How you deal with that fact is up to you but there's no point in denying it. Maybe Uthman did compile the best quran he could (given the memories of the people around him) but even so it is apparent that there were other versions around. So it is not possible to claim that the quran as we have it now is exactly what Gabriel gave to Mohammed because we have evidence to the contrary.
It
might be the same, if Uthman got it exactly right and if all the guys who memorised it got it exactly right, but we can't say for certain that the Uthman version is the "right" version because there are other, earlier versions which are different.
Maybe they are right and Uthman is wrong, who knows? If you can't say for certain who is right and who is wrong (and you can't) then you can't claim the quran is exactly the word of God. It might be approximately the word of God but not exactly. It's logically impossible to hold any other position when there are differing versions available.
Having said all that, I think Ramadan is a philosopically sound festival. I think fasting is good for the soul. So Happy Ramadan! And remember, hunger is just a state of mind.
