Importance of Conscience in the Qur’an

There is a voice that always inspires justice, good manners, humility, honesty, sincerity, and all that is most righteous. This voice, though you may be unaware of it, is always with you wherever you go. 'To whom does this voice belong?' you may then ask. Well, this voice belongs to you, it is within you, it is the voice of your conscience which is an inspiration from God and helps you to think straight and tell right from wrong.
