Those who believed (in the Oneness of Allāh - Islāmic Monotheism), and whose hearts find rest in the remembrance of Allāh: Verily, in the remembrance of Allāh do hearts find rest. (Surāh Ar-Ra’d 13:28)

 

Ibnul Qayyim (rahimahullah) said:

If your heart is distressed and troubled, then (know) there is nothing that will calm it other than the remembrance of Allah.
