Prophet Muhammad (ﷺ) said, “Allah has ninety-nine names, i.e. one-hundred minus one, and whoever knows them will go to Paradise.”
(Sahih Bukhari 50:894)

Abu Huraira reported Allah’s Messenger (ﷺ) 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 number..”
(Sahih Muslim Book-48 Hadith-5)
