The modern man, abandoned by modernism, has been crushed under the attacks on his spiritual life for three or four centuries. He has paid a heavy price for the advantages of modernity by being pushed into loneliness and spiritual crisis. The positive sciences, which he sought help from and deified, have failed to alleviate his troubles. Furthermore, despite their freedom to indulge all their carnal desires, spiritual distress has reached its extremes, and people have generally become monsters who drink each other's blood.
The Quran, which includes everything—even if only indirectly—has certainly also provided information about abstract concepts such as the soul, heart, mind, self, will, and conscience. Our aim in this research is to examine these concepts, which constitute the spiritual aspects of humanity, in light of the Quran. Then, just as diseases afflict the body, which constitutes the material aspect of humanity, so too do diseases afflict the soul, which constitutes the spiritual aspect, or prevent the soul from functioning healthily. Then, guided by the Quran, we propose remedies.
