Ok, explain yourself further. What point do you want to make?
dear mundi that is such a great question... great point ,,,,,, I am pulling my hair to answer that general
........... to my self (NOT TO YOU)., it is indeed tough.. What is the purpose? what point am i making by writing posts and asking question when i have gillion things to do?
.... Woff .. difficult one..
As far as this point / questions for you concerned ., the logic behind is very simple..
1. well i deliberately choose to show a fake inscription but apart from fakes there are many problems in inscriptions., such as interpretations of inscriptions and dating itself is a problem dear mundi .. but question to you.,
2, did you come across any publication that has highlighted Arabic inscriptions before Islam say between 3rd century to 6th century in the present Shia geographical area such as Iran, Iraq(Near the border towns of present Iran .. Basrah.. Amarah ..) and present Yemen ??
well there are serious scientific, logical problems and and questions in dating an object ., in fact it is much more difficult scientific problem to date accurately a graffiti or paintings, or writing on rocks than dating a rock itself... the error bars could be as high as 100 years or more....
2nd question to you is because I am under the impression that you are in touch with published literature on such subjects as proto-Islam .. Proto-Quran... ((years.. 550 to 630)) . concepts that may have originated in some Christian/Jewish/Arab pagan or Roman multi cultural environment... So the point is much of the Quran(NOT WHOLE BOOK) can be written anywhere including in areas such as Iran or even Yemen
So question to you was were there any prominent Christian /Jewish /Roman monasteries or prominent centers in these countries during early Islamic times
... and that is related to Quran..
We must realize Quran is a simplest book.,
it is a book of individual stories based upon OT/NT and bit of pagan stories that were floating around middle east .. The book is like a George Bernard Shaw play The Doctor's Dilemma
.. It is mainly a book of dialogues ., So many of these stories of Quran could have been written anywhere not necessarily in Syria or in Petra or in Jordan or in Israel/Palestine ..
well as usual let me add some publications/book links here
well many of those links should go in to resource center
