AOA Br. I agree, whole heartedly!
I didn't mean the verbal declarations, obviously. May be I'm not so good at coveying what I mean and have been blamed because of my lack of expression. I try again. :)
I meant as Muslims we do believe in the holy books mentioned in Quran.At the same time we also believe( and their followers also admit ) that they have been corrupted by human delusions. Surely! they tell us about the history ,yet they are not supposed to be regarded as 'historical books' either.
Similarly we believe through Quran that Allah sent His messengers to every nation He has created, yet they remained 'un-mentioned' to us.
Knowledge of either cases, corrupted and unmentioned both, is an asset of course for providing a solid base of argument, if necessary or to be convinced that some divine communication have been there and still persists after an ocean of time has flown past.
But if we'll keep on spending time and efforts on 'equalizing' 'dead' taleem and the 'living' knowledge, then we'll not be gaining anything, anymore, but probably will lose something we had before, I mean an opportunity to bring people to the beacon of true light-THE HOLY QURAN , or to a living NON-SECTARIAN RELIGION OF PEACEFUL BROTHERHOOD.
