Who wrote Quran?

Dea brother beloved thanks for your reply. As far "Then how is it reliable?" is concerned or even more stringently, about authenticity of ahadith is concerned, all comes in the domain of 'science of ahadith'. All issues of reliablity, authenticity and various gradation in them are scientifically looked upon and then accepted and is not a matter of faith at all. This is the reason, I referred you to that knowledge which is the basic before even alluding to it with such questions.

Now coming to your concern about "compilation", important thing to note is as what is meant by compilation at the two occassions i.e. compilation at the time of Prophet Mohammad and the compilation after wards. Compilation at the time of Prophet Mohammad refers to the process of putting all the written material in an ordered format, that is to say, the process of putting all the verses at their due positions; not necessarily in the form of a one unified book that we now see it. The later processes of compilation refers to making this loose but ordered peices/fragments transfer onto one and same kind of material on which it could be in written and thus forms one or more bound book/s.

O my dear brother beloved (with blinking eyes), its really not as difficult to understand as someone may think. Instead of arguing baselessly, hairspliting with "spelling mistakes" or otherwise, it would be more prudent to spend time in opening up the references that are provided.

Regarding your comments "So you mean to say that the compilation was verbal...." is not the logical outcome from my reply especially once the second paragraph is read along with it where I mentioned the process of later compilations as "..making this loose but ordered peices/fragments transfer ..". These both compilations were physical actions and not verbal alone. Though the orders for compilation from Prophet Mohammad must have been verbal, same way as the revelations were communicated to the scribes, but the actions of scribes to obey these commands to put them in an ordered format can't be considered verbal alone.

Regarding the names of the scribe, I realised that not all Islamic literature is available online, hence not readily accessable as I initially thought. Nevertheless, once you open up the Islamic literature books, you would definitely come across them as well.
