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

3:156

 

Yusuf Ali (Surat 'Āli `Imrān (Family of Imran) #03 of 114, verse #156 of 200)
O ye who believe! Be not like the Unbelievers, who say of their brethren, when they are travelling through the Earth or engaged in fighting: "If they had stayed with us, they would not have died, or been slain." This that Allah may make it a cause of sighs and regrets in their hearts. It is Allah that gives Life and Death, and Allah sees well all that ye do.
