What is the meaning of the verse, "And whoever turns away from the remembrance of the Most Merciful - We will appoint for him a devil, and he will be to him a companion" from Surat Az-Zukhruf, and what is the solution for dealing with a wife who suffers from whisperings regarding the Divine Self, the creation of the universe, and other theological issues?

"Whoever turns away from the remembrance of Allah, He appoints for him a devil to be an intimate companion for him in this world and the Hereafter, preventing him from what is lawful and commanding him to disobey. What has afflicted your wife is obsessive-compulsive disorder, and it is treated by remembrance [dhikr], supplication [du'a], seeking forgiveness [istighfar], and reciting the Quran, for indeed, by the remembrance of Allah hearts find tranquility. There is no objection to her consulting a psychiatrist."
