KNOW THE SIGN OF PIETY

Piety is not merely what you show outwardly. A righteous heart feels uneasy about sin, while a believer dislikes exposing what displeases Allah. Listen to your conscience. Fear Allah in private as you fear Him in public. And when something troubles your heart and you would hate for people to know of it, do not ignore that warning. Guard your heart. Abandon doubtful matters. Choose what brings you closer to Allah.
