The next verses in this chapter refer to some episodes in the life of the prophets. The beginning is with Moses and Aaron who were given a criterion to distinguish between right and wrong, true and false:ِ

      ``And We gave Moses and Aaron the Forghan (criterion), and a light, and a reminder for the pious.''

      The Arabic, ``FORGHAN'' principally is something which can separate the right from the wrong. It is a means of knowing these two. Some commentators have understood it to be the BIBLE. In cases too, FORGHAN has been used as another name for Qurän.

      As to the Arabic, ``ZIA'', it is a light emitted from the very substance of any lightgiving material, and this is the nature of all the SCRIPTURES, and the miracles, that the apostles have shown.

      The next verse (NO.49) introduces the men of piety:ِ

      ``Those who fear their Lord in private and dread of the Hour.'' (Resurrection Day)

      The Arabic, ``TAGHWA'' that We have translated to piety is some sort of a fear of running against the will of God which is set in the heart of the pious, or the virtuous. Such a fear is akin to the love of God.

      HAZRAT IMAM ALI (AS) was asked of the meaning of piety. In answer to this question he said:ِ

      ``Suppose you have all your deeds in a tray. If you are a pious man, you fear not to carry the tray, uncovered, on your head, and pass through a market.''

      This sort of Godfearing which causes such a said piety, will of course end to the salvation of the pious.

      There is also the dread of our evil deeds and its consequences in the life to come. This sort of fear may also end to Man's prosperity by giving a halt to evil deeds.
