Diseases of the Hearts and Their Cures 

Know O Beloved reader that it is most important to spend one’s time and energy in treating the heart, and hastening to correct and purify it from sickness and all sin. This is due to the heart occupying a great and lofty position in Islaam, for it is the place to which the Lord looks and the storehouse for tawheed, faith and sincerity.

The heart forms the foundation, it is the owner of the limbs, and the limbs are its soldiers, so when the owner becomes purified its soldiers become purified, and when the owner becomes sullied then its soldiers become sullied.
