The Illuminator, The One who Reveals, The One Who Guides.

Allah سُبْحَٰنَهُۥ وَتَعَٰلَىٰ call himself An-Noor (in Arabic: ٱلْنُّورُ), meaning The One who illuminates and reveals the divine light of all the worlds. His light illuminates the heart and provides clarity and guidance. Anyone who turns their back to the true light will be in darkness.
