Characteristics of a Pure Heart
By Shaykh AbdurRahman bin Nasr as-Sa’adi (d. 1376 A.H.) said:
‘A correct heart means a heart which is secured from Shirk and doubts, loving evil and is secure from being continuous upon Bida ‘ and sins. What necessitates for it to be correct from is the opposite of that which it has been described with, having sincerity, knowledge, certainty, loving goodness and beautifying it in the heart.
Also that whatever a person intends and his love follows what Allaah loves and his desires follow what came from Allaah.’
[Tayseer al Kareem ar-Rahmaan p. 593]
