Noor of the Heart

Rasulullah (sallallahu alayhi wasallam) said that when noor enters the heart, the (spiritual) breast of man expands. When the Sahaabah asked for a sign of this noor, Rasulullah (sallallahu alayhi wasallam) said: "Such a person flees from this abode of deception. He turns his attention to the abode of the Aakhirah and he makes preparations for it before the arrival of maut."

Thus, a man who has lost interest and desire in this world, has acquired this noor.
