(518) بَابُ إِذَا قَالَ أَهْلُ الْكِتَابِ: السَّامُ عَلَيْكُمْ
Jabir said, "Some of the Jews greeted the Prophet, may Allah blesshim and grant him peace, by saying, 'Poison be upon you (as-Samu 'alaykum)'and the Prophet replied, 'And on you.' 'A'isha, may Allah be pleased withher, said angrily, 'Didn't you hear what they said?' The Prophet replied,'Yes, and I answered them. What I said about them will be accepted andwhat they said about me will not be accepted.'"
