The Messenger of Allah ﷺ said, "Let the younger greet the older, the one passing by greet the one sitting, and the smaller group greet the larger."

This is also sahih due to the soundness of the manuscript, and it appears in the individual manuscript, number 48. Muslim narrated it, 53:7 S/2:201 Bulaq, through this route, but he did not mention its wording, referring instead to the narration of Abu Salama from Abu Hurairah that precedes it. Bukhari did not narrate it through the manuscript's route, but rather narrated it, 12:331 Fath, through the narration of Saeed bin Musayab from Abu Hurairah. It has already passed through the narration of Saeed bin Musayab, 7183, 7631.
