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

13:11

Yusuf Ali (Surat Ar-Ra`d (The Thunder) Surah #13 of 114, Verse #11 of 43)
For each (such person) there are (angels) in succession, before and behind him: They guard him by command of Allah. Allah does not change a people's lot unless they change what is in their hearts. But when (once) Allah willeth a people's punishment, there can be no turning it back, nor will they find, besides Him, any to protect.
