There is nothing that does not glorify Allah with praise, but you do not understand their glorification. He is Clement, Forgiving. Conscience is a spiritual quality given to us by Allah to guide us towards good behaviour and thought. It is universal, and speaks to all of us in the same way when given the same conditions. Through conscience, Allah lets us know what pleases Him, and it helps us to distinguish right from wrong.
Though it is our own responsibility to follow our conscience, failure to do so will bring regret and punishment in the afterlife. We must listen to our conscience, follow the Quran and the Messenger, and never turn away from the truth in order to gain entry to Allah's heaven. Life, therefore, is about listening to Allah's voice through our conscience, and taking action accordingly. Conscience is an integral part of understanding our life purpose and relationship with Allah. We are all subject to wrong-doing, but Allah's forgiveness is always available to us if we ask for it with a sincere heart.
His mercy and forbearance are infinite, and He will always forgive us.
