Abu Huraira (May Allah be pleased with him) reported that the Messenger
of Allah (peace and blessings of Allaah be upon him) said,
"Allah has ninety-nine names, one hundred less one. Whoever
ahsaha [enumerates them, believes in them, ponders their meanings, worships Allah by
them and supplicates with them, and acts by them according to one's belief in them] will
enter Paradise.
(Recorded by al-Bukhari and Muslim)
