Most Beautiful names of Allah, (أسماء الله الحسنى ) Subhan Wa Ta'ala: Asmāʾ allāh al-ḥusnā
Start With Name of Allah, ArRahmaneer ArRaheem
And (all) the Most Beautiful Names belong to Allâh, so call on Him by them, and leave the company of those who belie or deny (or utter impious speech against) His Names. They will be requited for what they used to do. (Quraan: Surat Al-A’raf 7:180)
Abu Hurairah reported Allah's Messenger [Muhammad] (may peace be upon him) as saying: "There are ninety-nine names of Allah; he who commits them to memory would get into Paradise. Verily, Allah is Odd (He is one and it is an odd number) and He loves odd numbers. And in the narration of Ibn 'Umar [the words are]: "He who enumerated them"."—Muslim ibn al-Hajjaj Nishapuri, Sahih Muslim
