Below is a reference to the Beautiful Name of Allah in Quran or Hadith:
Yusuf Ali (Surat An-Nūr (The Light) Surah #24 of 114, Verse #35 of 64)
Allah is the Light of the heavens and the earth. The Parable of His Light is as if there were a Niche and within it a Lamp: the Lamp enclosed in Glass: the glass as it were a brilliant star: Lit from a blessed Tree, an Olive, neither of the east nor of the west, whose oil is well-nigh luminous, though fire scarce touched it: Light upon Light! Allah doth guide whom He will to His Light: Allah doth set forth Parables for men: and Allah doth know all things.
