Muhammadan light; also called al-nur al-muhammadi. In the emanation scheme of cosmology characteristic of Sufi and Shii metaphysics, refers to the pre-cosmic soul of Muhammad, which is equivalent to the active intellect of Neoplatonism and associated with the perfect person (al-insan al-kamil) and Muhammadan truth (haqiqah muhammadiyyah). Represents the first creation (or emanation) of God, the self-manifestation of divine consciousness. All prophets preceding Muhammad derived their prophetic ability from the Muhammadan light. The doctrine appears in the writings of such early Sufi writers as Sahl al-Tustari and Hakim al-Tirmidhi and was later developed by Ibn al-Arabi and his school. The concept plays an important role in both Sufi and Shii concepts of sainthood (walayah).
