The Big Question: Why is there such a gap between what we are being taught and what the plain (normal) reading of the Qur'an the Before Books reveal?
It could easily be argued that the true words of Allah can not be changed or deleted in any way.
The Qur’an states many times that Allah’s words have been said and recorded plainly so that there can be no confusion. The source is reliable, plain and cannot be changed!
It can be also argued that people can change the interpretation, omit or distort words at will to suit their own agendas.
