The one who is riding should greet the one walking, the one who is walking should greet the one sitting, and the small group of people should greet the large one

Explanation

The Prophet (may Allah's peace and blessings be upon him) guides to the etiquette of extending the greeting of peace among people: "As-salāmu ‘alaykum wa rahmatullāhi wa barakātuh" (may the peace, mercy, and blessings of Allah be upon you). The young should greet the old, the one who is riding should greet the one walking, the one who is walking should greet the one sitting, and a small group of people should greet the large one.
