The argument returns once again to Monotheism of worship; that no one worths to be worshipped except Allah the only one true God. The verses here imply that all the living and non-living creatures prostrate themselves before God; even their shadows, which move from the right and left, are showing their submission to Him humbly!

      Physically, prostration is to recline with face on the ground, in adoration and worship. It is in fact the sign and symbol of showing one's submission.

      In the above verse, (NO.48) the immediate reference is to material things which are inanimate, and in the next verse, (NO.49) the act of prostration is applied to living creatures, such as men, animals, and angels, in other passages too, the Glorious Qurän claims that, whatever exist in the heavens and earth, celebrate the praise of God and prostrate themselves before him in submission and are humble, and they do what they are ordered to do!

      Although the shadow is physically nothing but the absence of light; it has many uses and benefits for man, and other moving creatures in the earth. Shadow will adjust and regulate the amount of light and sunshine, and control the effects of the sun's various and mysterious radiations, for the benefit of the living creatures down here. It provides for their rest and repose. Permanent shining of the sun will cause the flowers and plants and even the moving creatures to fade, and lose their freshness or brilliance. Those who have to work or to live in the deserts, for them, shadow is indeed a Mercy of God; and among the most useful means of living. After all; the shadow, dim and dark, weak or intense, serves to help vision and seeing things better and with more detail and resolution.

      By a mystical metaphor anything that exists in this material world, it is a shadow of its true reality in the heavens!

      In the last verse (NO.50) we read:ِ

      ``They fear Lord who is above them and they do what they are ordered.''

      Allah's hand of power is above all the hands. The learned, and men of knowledge and wisdom, as well as all the angels, are aware of this superiority in power; therefore, they are all watchful not to do something unjust, to encounter with God's justice and due punishment; and this is where we may say all of them fear their Lord.
