question #3 Sahih al-Bukhari 6543, Book 81, Hadith 132 : What does the imagery of the moon at night symbolize in the context of entering Paradise?

The Prophet (ﷺ) said, “Seventy-thousand or seven-hundred thousand of my followers (the narrator is in
doubt as to the correct number) will enter Paradise holding each other till the first and the last of them
enter Paradise at the same time, and their faces will have a glitter like that of the moon at night when it
is full.”
