Types of Hearts

From the spiritual and moral point of view there are different types of hearts. These types are related to their awareness and consciousness. In this respect, the Prophet is reported to have said,

"There are four types of hearts: a pure heart that shines like a lamp, the covered up and closed heart, the upside down heart and the mixed up heart. The pure heart is that of the believer. The covered up heart is that of the non-believer. The upside down heart is that of the hypocrite who knows and then denies. The mixed up heart is that in which there is both faith and hypocrisy. The example of faith in it is like a small plant that grows with good water and the example of hypocrisy in it is like a wound that grows with pus and blood. So whichever grows bigger takes over the heart." (Ahmad)
