Abu Huraira reported God’s messenger as stating that God says, “I am present when my servant thinks of me, and I am with him when he remembers me. If he remembers me inwardly I shall remember him inwardly, and if he remembers me among people I shall remember him among people who are better than they.” (Bukhari and Muslim.)
