The calmness of the heart is a stage beyond mere happiness and that only comes through true worship & remembrance of the Almighty.
When we learn to look at things positively it draws us closer to the Almighty. When we become closer to the Almighty we praise Him upon all conditions and remember Him.When we engage in the remembrance of the Almighty, we attain the calmness of the heart.
May the Almighty grant us both happiness as well as calmness of the heart. May He guide us to look at things positively and to engage in His Praise & remembrance upon all conditions.
Mufti Ismail Menk
