No one conceals something in his heart, but Allah causes it to be seen on his face or in a slip of the tongue.
Uthman ibn AffanAbsorption in worldly affairs breeds darkness in the heart, and absorption in the affairs of the next world enkindles light in the heart
Uthman ibn AffanAllah the Exalted loves him who forgoes worldly life, the Angels love him who rejects the vices, and the Muslims love him who gives up greediness in respect of the Muslims.
