The believers are only those whose hearts, when Allah is mentioned (before them), are filled with awe (at the very idea of Allah’s Greatness and Might). And when His Revelations are recited to them, they (i.e. the ecstatic, delightful, sweet and sublime Words of the Beloved) increase their faith, and they (maintain) their trust in their Lord alone (under all circumstances and do not look towards anyone other than Him).
