I think you are clutching at straws to provide a compelling case that the Quran is based on anything other than the words of Muhammad and doubt if any serious scholar would try that. Even the myopic Christian apologist Kirk MacGregor believes:
The historical evidence from the Qurra and the manuscript evidence from Sana’a indicate
that the traditional text of the Qur’ān as it exists today, while generally reliable, departs in crucial
respects from the Arabic text as it was originally recited by the Prophet Muhammad.
I am not clutching at straws to prove anything - I am simply stating the fact that despite the Bahai swallowing hook, line and sinker the traditional Islamic tale about how the Qur'an has come down to us completely intact, this cannot possibly be verified and that there is considerable reason to doubt it.
In fact, according to Shi-ite tradition is it not true that the very person who was responsible for standardizing the text of the Qur'an as we know it today (the 3rd Caliph, Uthman) was himself accused by his fellow Muslims of "changing the Qur'an"?
And do we not understand from the same traditions that Uthman ordered the destruction of all Qur'ans that did not conform to the standard text? We therefore know, don't we, that there was, already - just a couple of decades after Muhammad's death - considerable variation among the copies of the Prophet's words that had been made by then (and even more variation among the already growing variety of
hadiths) that this was already a major concern for the leaders of the nascent Islamic empire?
And do we not know from the same tradition that this concern was serious enough to lead to the assassination of Uthman himself?
And do we not know from the same tradition that it was, in fairly large measure, this very concern that brought Muhammad's cousin Ali to power as the 4th Caliph? Ali - presumably being a wise and politically savvy leader - seems to have decided not to interfere too much with the content of the Qur'an and Uthman's standardized text became the one on which future copies were made. But we have no way of knowing the full extent of the various texts that had come about - especially if they were - as the same tradition holds - destroyed during Uthman's Caliphate if they did not conform to the text as approved by his committee.
None of this is clutching at straws is it? None of this is my imagination is it? In fact, it is either true, or it is the imagination of the very Shi-ite "historians" of Islam that Baha'is depend on for their understanding of how the received text of the Qur'an came down to us as the intact words of the Prophet Muhammad, isn't it?
You can counter quote (out of context) all you like but the facts remain that there are very few copies of the Qur'an dating back earlier than a couple of centuries after Muhammad and what there are show considerable variation from the received text - whether or not they are the words of Muhammad - much less the words of God.
And of course the situation with the Bible is even worse - how that is relevant I don't know (except that you wanted to use
argumentum ad hominen to discredit the author of the paper I quoted rather than disproving the content of what he wrote) - and it "runs rich with hypocrisy" (to use your own terminology) that you choose to include such a comparison immediately after censuring Antony and I for not focussing on Muhammad and Baha'u'llah! What was it Abdu'l Baha asked for - a "just judgement"? Well c'mon Adrian - neither of these tactics are fair are they - and how can we reach a "just judgement" on Muhammad if you refuse to play fair?
