The Heart

"The heart becomes sick just as the body becomes sick, and its cure is repentance and protecting it, just as the body's cure is in medicine and protecting it from harm."

"The root of all hardheartedness is preoccupation with the dunya and long hopes."

"If the hearts are purified, they would never have enough of reciting the words of Allah."

"The heart rusts like iron, and its polish is the remembrance of Allah."

"Whosoever desires to purify his heart, then let him prefer Allah over his desires."
