"Knowledge without Benefit, Heart without Allah's fear, Soul without contentment, Du'a without response"

Messenger of Allah S.A.W.S. supplicated

"O Allah, grant to my soul the sense of righteousness and purify it, for Thou art the Best Purifier thereof. Thou art the Protecting Friend thereof, and Guardian thereof.
O Allah, I seek refuge in Thee from the knowledge which does not benefit, from the heart that does not entertain the fear (of Allah), from the soul that does not feel contented and the supplication that is not responded."
