(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.
