We
Learn from this that:
The
remembrance (dhikr) of the Most Merciful is the remembrance
He sent the Messenger (SAW) with, such as the
Qur`an. Therefore whosoever does not believe in the
Qur`an, accept its narratives to be true and believe in the
obligation of its commands has turned away from it
and as a result is assigned a devil who accompanies
him.
