Question: I sometimes feel afraid when I sleep by myself in a room or in my room. I feel compelled to play the Quran because I am able to sleep upon hearing its verses. Is this permissible?
Answer (by Shaikh Bin Baz): I do not know of anything wrong with this. Because the Quran is the companion of the Believer. And it is the remembrance of Allaah, The Mighty and Majestic. Listening to it is worship. So when a person needs to listen to it to remove anxiety or to put his heart at ease, then there is no problem with that. Alhamdulillah.
