Absorption in worldly affairs breeds darkness in the heart, and absorption in the affairs of the next world enkindles light in the heart
Uthman ibn AffanEnjoin what is good and forbid what is evil before the worst amongst you are given authority over you and then when even the best of you make dua against them, their duas will not be accepted.
Uthman ibn AffanNo one conceals something in his heart, but Allah causes it to be seen on his face or in a slip of the tongue.
