The Prophet (peace be upon him) said: Allah has ninety-nine names, one hundred less one. Anyone who learns them will enter Jannah. According to another narration: Anyone who memorizes them will enter Jannah. (Agreed upon by Al-Bukhari and Muslim).
This Hadith urges us to consider carefully, ponder over, memorize and learn the Names of Allah, so that we can benefit from their great meanings, gain Khushu` (the heart being submissively attuned to the act of worship), obey Allah and fulfill our duty towards Him(Glorified and Exalted be He).
