There are five dark matters and five lamps. Love of this world is darkness, and the fear of Allaah is its lamp. Sin is darkness, and its lamp is repentance. The grave is darkness, and its lamp is 'none has the right to be worshipped but Allaah, and Muhammad is the messenger of Allaah.' The hereafter is darkness, and its lamp is the good deed. The Siraat is darkness, and its lamp is certainty of faith.
Abu Bakr
