Sunnah Tawatur And Ijma
That’s what I’m saying- how do we know without documented proof of the past that there weren’t any changes?
Qiraats aside, how do you even know that it’s the same Quran that was given by Prophet Muhammad (sws) and no changes have been made to it ever since? Where is the documented proof of original Quran? (Qiraat is a separate issue which I am not addressing at the moment). Why there is no demand for documented proof of Quran (the original words) just the way it is for documented Sunnah?
