In these two texts, especially the Holy Quran, using literary devices and methods, including simile, metaphor, apostrophe, limitation, emphasis, and other rhetoric elements; benefiting from a sound heart and applying its principles are considered as one of the causes of moral development and providing mental health of human beings. And in the case of deviation and inclination to the sick heart, the grounds for the inclination to moral vices, mental illness, and mental health disorders and abnormalities increase.
