U Avinash are the right authority on Kuran...sad even the highly educated muslim will not agree with u on the concept which u wrote..though its simple common sense..as far as muslims go..they have this fixed in their mind that Kuran fell from the skies and nothing can change..all histroy and all things in this world is there in the koran ..began with koran and ended in koran..its all frozen in koran..nothing can change it..but the fact is that Mohmed never wrote the Koran..neither did mOhmed verify this koran..infact Koran was manufactured after destroying all the originals..so we have an edited manufactured koran..not even verified by Mohmed..as mohmed was dead..200 yrs after his death was koran created....and we do not even have the originals to verify the changes in it...
