question #3 Sahih al-Bukhari 6233, Book 79, Hadith 7 : What is the significance of greeting a larger group of people when you are in a smaller group?

Allah’s Messenger (ﷺ) said, “The riding person should greet the walking one,
and the walking one should greet the sitting one, and the small number
of persons should greet the large number of persons.”
