The criterion or discernment (al-furqan), light and reminder or remembrance (dhikr), which were given to Moses, were the same things which all the prophets received from God. Al-furqan means that ideological standard which enables a man to distinguish between Truth and falsehood. Light means divine guidance which pulls a man out of the darkness of the wrong path and puts him on to the straight path. Dhikr means remembrance, i.e. the highlighting of the latent educative aspect of things, so that they do not figure simply as things, but as treasure chests of knowledge for the recognition and realisation of God and His Divine guidance. In this way God has arranged for the guidance of man. But, it is possible for God’s Guide Book to provide guidance in the real sense only when a man is anxious about his fate in the Hereafter, and this anxiety makes him so serious that he attaches more importance to Truth and righteousness than to all other things.
