Sayyiduna Imam Hasan bin Ali (may Allah be pleased with them both) narrates: It was said: "O Messenger of Allah! Some people come to a house, and one of them asks for permission; will that suffice for all of them?" The Prophet (peace and blessings be upon him) said: "Yes!" It was said: "If one person from among those people returns the greeting, will it suffice on behalf of all of them?" The Prophet (peace and blessings be upon him) said: "Yes." It was said: "If some people are passing by and one of them gives the greeting of salam, will that suffice on behalf of all of them?" The Prophet (peace and blessings be upon him) said: "Yes." It was said: "If one person from among those people returns the greeting, will it suffice on behalf of all the people?" The Prophet (peace and blessings be upon him) said: "Yes."
Tabarani recorded it, and its chain contains a narrator, Kathir bin Yahya, who is da'if (weak).
