To the Sufis, nūr is the first creation of Allah, and all other things and beings were gradually created from it.[15] The Andalusian scholar Abu Bakr ibn al-Arabi (1076–1148)) elaborated the concept that Muhammad existed before creation. This is the doctrine of An-Nūr al-Muḥammadī, or the Muhammadan Light. The light existed before creation, and everything was created from it.
