A Probe into the Meaning of Light in the Qur'an and Hadith
The word light (nur) has been applied in the religious texts to a variety of instances. These instances involve a wide spectrum of beings whose one extreme is the visible light, whilst the other extreme is the divine Essence. Entities situated between these two extremes such as intellect, knowledge, faith, divine messengers and their successors, guidance, and the like, have also been referred to as light. Nonetheless, the possession of light by all other beings is by virtue of the perpetual Essence of God.
