The Messenger of God said, "There are four kinds of hearts: There is a bare heart within which is a
shining lamp, and this is the heart of the person of faith. There is a black and inverted heart, and this is
the heart of the unbeliever. There is a heart bound by attachments, and this is the heart of the hypocrite.
And there is a layered heart, within which are both faith and hypocrisy. The faith within it is like a plant
nourished by sweet water, while the hypocrisy within it is like a boil nourished by pus and filth. The heart
will be judged by whichever nourishment dominates over it"
"Silence is the veil of the ignorant and the adornment of the wise"
