that the Prophet (ﷺ) passed by a gathering in which the Muslims and the Jews were mixed, so he gave the Salam to them.
Jami` at-Tirmidhi Book 42, Hadith 15
← Previous Hadith that a group of Jews entered upon the Prophet (ﷺ) and they said: "As-Samu 'Alaik (death be upon you)." So the Prophet (ﷺ) said: "Wa 'Alaik (And upon you)." So 'Aishah said: "I said: ' upon you be death and the curse.'" So the Prophet (ﷺ) said: "O 'Aishah! Indeed Allah loves gentleness in every matter." 'Aishah said: "Did you not hear what they said?" He said: "And I replied: 'And upon you.'"

Jami` at-Tirmidhi Book 42, Hadith 14 Next Hadith → from Abu Hurairah that the Prophet (ﷺ) said: "The rider gives the Salam to the walking person, and the walking person to the sitting person and the few to the many." Ibn Al-Muthanna added in his narration: "And the young one gives the Salam to the elder."
