Mukhtasar Bukhari (Abridged) 1264 — Cursing polytheists and praying

Narrated from Ummul Momineen Aisha Siddiqa (may Allah be pleased with her) that the Jews (one day) came to the Prophet Muhammad (peace be upon him) and said, "Death be upon you." So I cursed them. The Prophet (peace be upon him) said, "What happened to you?" I said, "Did you not hear what they said?" The Prophet (peace be upon him) said, "Did you not hear what I replied? I said, 'And upon you' (meaning, whatever you have said is upon you)."
