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. And in the narration of Ibn 'Umar (the words are):" He who enumerated them."
Abu Huraira reported Allah's Apostle (ﷺ) as saying
Verily, there are ninety-nine names for Allah, i. e. hundred excepting one. He who enumerates them would get into Paradise. And Hammam has made this addition on the authority of Abu Huraira who reported it from Allah's Apostle (ﷺ) that he said:" He is Odd (one) and loves odd number."
