Refuting misconceptions:3-Authenticity and preservation of the Quran

[Rwandrall]

1-it says in the Quran it will be preserved:

If any changes happened you would have seen a lot of muslim in this time leaving islam as it would be a prove that the Quran is not a revelation from god but that never happened but in fact islam in this time was increasing

Both of these assertions are nonsense.
The Quran will be preserved because says the Quran will be preserved...circular argument, stop using them because it makes you look like a blind fool.

The changes made to a religious text are often not perceived by the masses, or supported by their shepherds so they accept it. The Bible has been extensively modified over its first 2 centuries of existence, some texts have been thrown in, some texts have been cut out, many texts have been changed. Even a few years ago, when the Church had a debate between keeping the Mass in Latin or having it in the country's language, there was a lot of divisions between the communities, but very few actually left the Church. There is no reason why the Quran would be any different.
Even if their objection would have been to the Quran being changed, most were not even aware of these changes, i mean 1400 years ago very few people could even READ !

2- during muhammed(pbuh)life:

- memorization
It’s a unique thing in islam that people use to memorize all of it as all muslims pray 5 times a day(at least) rectating some of the Quran in the prayer loudly infront of a lot of the muslims imagine this happening for 23 years by thousands of muslims and also in their prayers alone at night(some of them use to pray for 3 or 4 hours at night)
-annual review
Review of the entire Quran in ramadan by the people memorizing it with muhammed (pbuh) himself( as it is still done today)
-companions wrote it:
There was a lot of his companion who were delegated to write the revelations like: Abu Bakr, Umar, Khalid Bin Al-waleed, Zayd ibn Thabit, `Ali ibn Abi Talib, Aban, Bin Said, Mu`awiyah and others(plus the other companions memorizing it also others writing personal copies) all done during the time of the Prophet under his direct supervision.

Even if they did know the Quran by heart, you cannot claim that they transmitted it through the 1400 last years without any alteration made, by word of mouth. The paper support had to be there. And as such, if the written book is altered, then the word transmitted through the generations is altered as well.

3-After muhammed(pbuh) death:

The quran was totally written and there was thousands of people memorizing it as a whole and some memorizing parts of it and in the time of abu bakr the first caliph 70 of the memorizer died in a war called el yamama (2 years after muhammed(pbuh) death) so they decided to unite the material of the Quran as it was written in different materials with different companions

Wrong, follow the link provided, that is just an assertion you make without evidence.

4-The criterea of unifying the material to paper:

Zayd ibn Thabit was resposible for this(one of the memorizers of the whole Quran and also was delegated from the prophet himself to write the Quran)
a- He required the presence of two witnesses to testify that this copy was written by the order of the Prophet under his instructions and in his presence.
b- Another two witnesses must also have memorized the contents of such a copy.
c- The members of the presiding committee also memorized the contents, although none of them were accepted as witnesses.
Thus, each copy presented had at least five witnesses: the owner of the manuscript or document, the memorizers, and the two witnesses who witnessed the writing during the time of the Prophet himself. In addition, Abu Bakr and Umar supervised this entire process
That was a compilation of thr Quran not writing and then this copy was kept in the custody of abu bakr and after his death in the custody of umar the second caliph and after his death it was in the custody of hafsa the daughter of umar(to the people thinking that woman was inferior the original copy of the Quran was under a custody of a woman for over 5 years)

Witnesses are irrelevant because they are not objective witnesses, they were all followers and as such cannot be trusted as proof that their master was doing his job right. And even if there were objective eye witnesses, this does not constitute sufficient evidence for the perfection of the Quran. You will probably ask how its preservation can be certain: as for all books, you need to provide the original. Otherwise, there is no definite evidence of your book's preservation.

I cannot comment on "5" as i do not possess the relevant expertise.

6-When do people start changing the religious books:

1-when it does not contain their claims or doctorines
2-when they don’t want to follow its commandments
3-when there is different opinions and they want to force their opinion
4-when they lose the original copies and have many books claiming to be the word of god

7-How to assure the credability of a divine book:

1- the book should contain the major beliefs of the people following it
2-All verses in such manuscripts or books should be accepted by the followers of the respective religion.
3-no different versions or people having hard time saying what is from the book and what is not
4-no anonymous writers the writers must be known
5-you don’t find anyone trying to change or add to the current book
6. The book should include the message of God only as conveyed by the respective prophets and not doctrines or teachings of humans who are supposed to be followers of the prophets.
7-there must be at least one original copy in the original language dating to the time of the prophet or close to his time.
8- The original manuscripts should not contain any variances or contradictory accounts of the same events.

ok guys i couldnt make it shorter than that but hope it will answer the people asking about Quran authenticity after this thread i will take a little rest from refuting misconceptions and will concentrate more on atheism so anyone who wants to know about other subject regarding misconceptions about islam just ask and i will put it in mind and then we can continue later about anything you guys think about islam

This is a very bad argument: the people who altered the Quran had plenty of time to make it look credible.
