Ar-Rahman - The Compassionate, The Beneficent, The Gracious
Below is a reference to the Beautiful Name of Allah in Quran or Hadith: 

Yusuf Ali (Surat Ar-Ra`d (The Thunder) #013 out of 114, verse 30 of 43)

Thus have we sent thee amongst a People before whom (long since) have (other) Peoples (gone and) passed away; in order that thou mightest rehearse unto them what We send down unto thee by inspiration; yet do they reject (Him), the Most Gracious! Say: "He is my Lord! There is no god but He! On Him is my trust, and to Him do I turn!"
