(Nur) is the created light which radiates from the Uncreated Light of Allah. When this light enters the heart it drives away the existent order thereby annihilating the inner eye from witnessing 'other-than-Allah'. For unveiling to take place the Light which comes from Allah must coincide with the light within the heart. If there is darkness within the heart, then it will not be able to match the Light from Allah. In such a case there is no unveiling, and Knowledge of Allah does not arrive in that heart. It is the Remembrance of Allah which polishes the heart and allows it to be filled with light. The Source of this Pure Light is the Absolute Darkness of the Essence Itself. The most complete and penetrating light is the light through which is unveiled what Allah means by the forms seen by the imagination in dreams.
(Nur Muhammadiyya). "Allah took a handful of His Light and said 'Be! Muhammad'". From this pre-existent Light of Muhammad (nur Muhammadiyya) all of the spheres were created. It is the Light of Muhammad that enables the traveller to advance towards the Reality of Muhammad (al haqiqa al Muhammadiyyah). Without the cooling nature of this light the salik would not advance, or if he did advance he would be burned-up. The differentiation between the Light of Muhammad (nur Muhammadiyya) and the Reality of Muhammad (al haqiqat al Muhammadiyyah) is within the degrees of the descent of Being, from the Inward Non-manifestation of the Hidden Treasure to the outward manifestation of the cosmos.
