Rituals of a Worshipping Heart

As such, it discussed five heart-related acts of worship around which the actions of all limbs revolve:
Al-Ikhlas (Sincerety)
At- Tawbah (Repentance)
At-Tawakkul (Reliance on Allah)
Al-Khawf (Being afraid of Allah)
Ar-Rajaa (Hope in Allah)

All these were followed with the mentioning of some important basic characters connected to the heart as examples of other beautiful characters and enviable attributes.
