Narrator:Abdullāh ibn ‘Umar
حَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" إِنَّ الْيَهُودَ إِذَا سَلَّمَ عَلَيْكُمْ أَحَدُهُمْ فَإِنَّمَا يَقُولُ السَّامُ عَلَيْكُمْ . فَقُلْ عَلَيْكَ "
Yahya related to me from Malik from Abdullah ibn Dinar that Abdullah ibn Umar said that the Messenger of Allah, may Allah bless him and grant him peace, 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'."
