In the Qur'an we read that God is the Light of the heavens and of the earth. This explains to us that if the Creator is the light of the heavens and of the earth, if the Creator Himself is light, then the, whole creation is His light also. Therefore if we wish to know the secret of the nature of the heavens or of the earth, we can learn it by studying the nature of light. There is nothing more attractive to our eyes than light, nothing more elevating. Every heart feels full of delight in the light of the sun.
