It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever commits a sin in this world and is punished for it here, then Allah Almighty is more just than to punish such a servant again. And whoever commits a sin in this world and Allah Almighty conceals it and forgives him, then He is more gracious and merciful than to call him to account for a sin which He has already forgiven.
