Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: Some people will come whose hearts will be extremely soft. (The narrator says) Then the people of the Ash‘ari tribe arrived, among whom was Sayyiduna Abu Musa Ash‘ari (may Allah be pleased with him). Those people were coming while reciting this rajaz and saying: "Tomorrow we will meet our beloved ones, we will meet Sayyiduna Muhammad (peace and blessings be upon him) and his group."
