Below is a reference to the Beautiful Name of Allah in Quran or Hadith: 



Yusuf Ali (Surat An-Naml (The Ant)  #27 of 114, verse #64 of 93)
Or, Who originates creation, then repeats it, and who gives you sustenance from heaven and earth? (Can there be another) god besides Allah? Say, "Bring forth your argument, if ye are telling the truth!"
