What actual difference does it make, to the message from God, whether chapter 9 starts with ?Basmallah? or not?
The chapters names are, in any case, not from God; are the chapter numbers?
To my mind, the significance lays in the fact that we may refer to a verse through a number, or other means of easy identification, that is commonly agreed upon, but only for easy reference amongst ourselves.
To add in, or subtract, anything from the text of the scripture that we have, is based on conjecture, not facts, and I believe we should avoid that.
To only accept ?Basmallah? as breaks between chapters may, or may not, be according to Allah?s will.
I am more inclined to think of the whole scripture as one undivided message, but for the straight forward verses and the verses with multiple meaning.
Or have I missed something?
