What is the reason for a married woman, mother of a child, to feel intense fear of death, to dislike people and speaking, to neglect herself and her home, and to experience intrusive thoughts during prayer and Quran recitation, given that there is no organic cause for these symptoms?

Remembering death and preparing for it is important, but it should be done in moderation. It should not dominate the mind or distract from duties and acts of obedience, as this is from the whispers of Satan. The servant should keep death in mind to be active in acts of obedience, increase repentance, and stay away from sins, with the certainty that the appointed time is fixed, neither advancing nor delaying. The cure for obsessive whispers is to disregard them.
