Musnad Ahmad 14084

Translation

✧ A Jew passed by the Prophet ﷺ and his companions and said, “As-samu ‘alaykum” (death be upon you). The companions of the Prophet ﷺ responded to him, and the Prophet ﷺ said, “He only said, ‘As-samu ‘alaykum.’” So the Jew was seized and brought, and he confessed. The Prophet ﷺ said, “Respond to them with what they said.”
