w/salaam Saba,
Thanks for the feedback, but I hope you read past the first point!
And as to your question: nowhere did I state nor imply what you seem to imply with your questions. However, with regard to the gist of your objections, if an understanding cannot be understood on its own, i.e. using Quran (and by "using Quran" I also mean its guidance with regards to method/verification/etc) then this is problematic.
Further, if such an understanding requires finessing of word meanings, its grammar, no supporting Quranic evidence of any kind for any of its key terms, suspension of logic, awkward application etc then it is almost certainly a wrong understanding.
Analysis is simply a matter of putting evidence on the table, so to speak, then weighing it up. That is my aim. You may think some things do not matter, or are a "major problem", others might disagree with you, hence I prefer to point it out and put it on the table for all to see. If you, or others, disagree, each to their own.
Of course, if you, or anyone, has answers to the points, feel free to put it on the table.
