“And that person who was dead, we gave him life and we granted him a light because of which he walks amongst people.” (Surah al-An’am, Verse 122)
A heedless person is like a corpse, whereas truly alive is the one who is constantly engaged in remembering Allah
. Through the abundant remembrance of Allah the heedless heart of a person is transformed into a living one. Hence, this light of nisbah (spiritual connection) is such a blessing that it gives life to the heart that was once dead and devoid of the remembrance of Allah.
Different people display different signs of the attainment of this light. This light in the language of our mashaikh (spiritual elders) is also called faidh, barakah, rahmah, and noor. All these words point to the same blessing. Attainment of faidh means the attainment of illumination. When a person gives bayt (pledges allegiance) to a shaykh and engages in the remembrance of Allah (dhikr) he attains faidh through this dhikr and his heart fills with noor. His heart attains peace as a result.
Light and darkness cannot coexist in the same space. Whenever noor enters the heart of a person he achieves tranquility, and whenever his heart is engulfed by darkness he is in a state of perpetual anxiety. Darkness causes unrest and confusion while noor brings peace.
