[Machine] The Prophet ﷺ came across some people from the Jewish community and they greeted him by saying, "As-Salamu 'Alaikum, O Aba Al-Qasim." The Prophet ﷺ replied, "Wa 'Alaikum." Aisha then said to them, "May the curse and disgrace be upon you." The Messenger of Allah ﷺ said to Aisha, "O Aisha, do not use foul language." She then said, "O Messenger of Allah, did you not hear what they said? They greeted you with 'As-Salamu 'Alaik.' " The Prophet ﷺ asked her, "Did I not respond to them by saying 'Wa 'Alaikum'?" I said to them what they said to me. Ibn Numair reported that in his narration of the incident, Aisha said, "Indeed, Allah dislikes vulgarity and indecency." Ibn Numair also reported in his narration that this verse was revealed: "And when they come to you, they greet you with a greeting from which Allah has not greeted you." And it continued until it was completed.
