Narrated Ibn `Umar
Allah's Messenger (ﷺ) said, "When the Jews greet anyone of you they say: 'Sam'Alaika (death be upon you); so you should say; 'Wa 'Alaika (and upon you).'"
Narrated `Abdullah
As if I am looking at the Prophet (ﷺ) while he was speaking about one of the prophets whose people have beaten and wounded him, and he was wiping the blood off his face and saying, "O Lord! Forgive my, people as they do not know."
