Dear Sister Lali.
I do not believe the Qu'ran to be a concealed message within itself. I agree with your quoted verses of the Qu'ran.
I was simply asking bkanwar why he believes that it Allahs message to guide mankind would be a message concealed within itself for us to be confused over.
Allahs plan(whatever they are) is not to play games with us. Allah wants only the best for us.
Playing tricks seems.. rather ungodly if you ask me.
