According to search-discovered classical Islamic scholarship, Ghaflah (الغفلة) is the spiritual disease of 'heedlessness'—a state of forgetting Allah and neglecting one's ultimate purpose. Ibn Kathir's analysis of verses like 16:108 explains that this is not mere forgetfulness, but a deliberate turning away that results in Allah sealing the heart, hearing, and sight from guidance. This state is vividly described in Quran 7:179, where the heedless are deemed 'like cattle, nay even more astray' because they fail to use their God-given faculties of intellect and perception. The great spiritual master Al-Ghazali categorized Ghaflah as a primary sickness of the soul, stemming from excessive love for the world. Ibn al-Qayyim clarifies the distinction that Ghaflah is a choice, unlike Nisyan (simple forgetfulness), and thus one is held accountable for it. The synthesis of these scholarly views across the Quran's 24 key verses on the topic establishes Ghaflah as a critical spiritual barrier whose only cure is its opposite: the conscious, consistent, and heartfelt practice of Dhikr (remembrance of Allah).
