Hearts are Four Kinds

Abu Sa`id Al-Khudri (Radhi Allahu Anhu) said, "The Messenger of Allah (Sallallahu Alayhi wa Sallam) said:

“Hearts are of four kinds: the heart that is clear like a shining lamp; the heart that is covered and tied up; the heart that is upside-down; and the heart that is clad in armor. As for the clear heart, it is the heart of the believer in which is a lamp filled with light; as for the covered heart, this is the heart of the disbeliever; as for the upside-down heart, this is the heart of the hypocrite, who recognizes then denies; as for the armor-clad heart, this is the heart in which there is both faith and hypocrisy. The parable of the faith in it is that of legume, a sprout that is irrigated with good water, and the likeness of the hypocrisy in it is that of sores that are fed by blood and pus. Whichever of the two prevails is the characteristic that will dominate.” (Imam Ahmad classified it as good (Jayyid))
