What is the meaning of "whoever enumerates them shall enter Paradise"?

Counting the beautiful names of Allah involves memorizing them, knowing their meanings, and acting in accordance with their implications, such as knowing that He is "The One" (Al-Ahad), so one should not associate partners with Him, and that He is "The Provider" (Al-Razzaq), so one should not seek provision from anyone else. It also includes supplicating to Allah using these names, choosing the appropriate name for what is sought, and for the worshipper to engage in acts of worship that are consistent with these names.
