All creations come into being from that unique source of light which was kept in great secrecy.That noor(spiritual light) of the enlightened essence of Allah lies in all creations as lifeblood.Even no molecule or particle couldn't come into existence without His noor(spiritual light).All the creations because of the existence of His(Allah)spiritual light in them dispersed from His enlightened essence every moment keep on remembering Him(Allah) to be merged into Him.
The cursed place where the souls of the sinful people rest till the revival is called sizzin(hell).Similarly the ruh(spirit) or the essence of Allah exists in a latent condition in human being.When a man loses his human qualities then thatruh(spirit) undergo intense unrest in a captive condition in body.That condition in human life is also a kind of sizzin(hell).
