Re: Dijjal
Semi, your statement has an inherent assumption that everything borne by Gabriel to Muhammad SAW was the Quran. This is an incorrect assumption.
The Quran was promised to be kept unchanged or pure in the sense nothing was added to it. Sacred, anything can be considered sacred by our perception.
Probably the wrong thread for this, but why was some of what was revealed to him in the Quran and so much left out? It seems it is very important to Muslims that the Quran is unchanged, yet the accept hadith as if is something more than the writings of what someone heard someone else say they heard from someone else that Muhammed said in his presence.
