What is your advice for a friend who has distanced herself from the Quran and prayer, believes that Islam is of no benefit, and is experiencing bad dreams?

If a woman abandons prayer and severs her connection with the Qur'an, believing that Islam is of no benefit, then she is an apostate, especially if efforts were made to convince her without success. The disturbances, distress, and bad dreams she experiences are a result of her turning away from the Qur'an, fulfilling the words of Allah Almighty: "But whoever turns away from My remembrance - indeed, he will have a difficult life, and We will gather him on the Day of Resurrection blind." So, if she desires comfort and happiness, she must return to the Qur'an and faith.
