Allah the Most High says in the Quran: 'Verily, in the remembrance of Allah do hearts find rest.' (13:28). The Qadri tradition emphasizes dhikr as the central pillar of the spiritual path.
"Make your tongue always moist with the remembrance of Allah." — Hadith
Regular dhikr gradually dissolves the veils between the servant and their Lord, illuminating the heart with Divine light.
