Hadith - Sahih Bukhari Book 25, Number 5389, Narrated AbuHurayrah
Allah's Messenger Sall Allahu Alhy Wasalm said: Do not greet the Jews and the Christians before they greet you and when you meet any one of them on the roads force him to go to the narrowest part of it.
Hadith - Malik's Muwatta Book 53, Number 53.2.3
Yahya related to me from Malik from Abdullah ibn Dinar that Abdullah ibn Umar said that the Messenger of Allah said, "When a jew greets you, and says 'Death to you' (as-samu alaykum) say, 'And to you.' "
Yahya said, "Malik was asked whether a person who greeted a jew or christian, should apologise for it. He said, 'No'."
From Jaabir Ibn Abdullaah who said: "Men from amongst the Jews greeted the messenger of AllaahSall Allahu Alhy Wasalm . So they said: 'As-Saam Alay Kum (May death be upon you) o Aba-al-Qaasim.' So he said, 'And unto you' (Wa Alay Kum). So Aa'ishah(r) became angry, and she said, 'Did you not hear what they said!?!' So he said, 'Indeed, and I returned it on them, and verily we answer them, and they don't answer us.'"
