Below is a reference to the Beautiful Name of Allah in Quran or Hadith:
Yusuf Ali (Surat An-Naml (The Ant) Surah #27 of 114, Verse #40 of 93)
Said one who had knowledge of the Book: "I will bring it to thee within the twinkling of an eye!" Then when (Solomon) saw it placed firmly before him, he said: "This is by the Grace of my Lord!- to test me whether I am grateful or ungrateful! and if any is grateful, truly his gratitude is (a gain) for his own soul; but if any is ungrateful, truly my Lord is Free of all Needs, Supreme in Honour !"
