846/1106 (Sahih) From Abdullah ibn Umar; he said: The Messenger of Allah, peace and blessings be upon him, said: "When one of the Jews greets you, he only says: 'As-sam upon you.' So say: 'And upon you.'"

847/1107 (Hasan) from Ibn Abbas who said: "Return the greeting of peace to whoever it may be, whether he is a Jew, a Christian, or a Magian; that is because Allah says: ?And when you are greeted with a greeting, greet in return with what is better than it, or at least return it? [النساء: 86] ."

848/1108 (Sahih) From Usama ibn Zayd: "That the Prophet, peace and blessings be upon him, rode on a donkey that had a saddle covered with a Fadakiyah velvet cloth, and he seated Usama ibn Zayd behind him; he went to visit Sa'd ibn 'Ubadah, until he passed by a gathering in which was Abdullah ibn Ubayy ibn Salul—and that Abdullah had become Muslim (2)—and in the gathering were a mixture of Muslims, polytheists, and idol worshippers, so he greeted them with peace."

849/1109 (Sahih) From Abdullah ibn Abbas: That Abu Sufyan ibn Harb informed him, Heraclius the king of Rome sent for him, then he called for the letter of the Messenger of Allah, peace be upon him, which [أرسل به] (1) was with Dihyah al-Kalbi to the chief of (Busra), so he handed it to Heraclius and he read it, and in it was: "In the name of Allah, the Most Gracious, the Most Merciful. From Muhammad, the servant of Allah and His Messenger, to Heraclius, the chief of the Romans. Peace be upon those who follow the guidance. To proceed; I invite you with the call of Islam. Submit and you will be safe; Allah will grant you your reward twice; but if you turn away, then upon you is the sin of the Arians. And: O People of the Book, come to a word that is just between us and you... to His saying: bear witness that we are Muslims [آل عمران: 64] ."

850/1110 (Sahih) From Jabir who said: Some people from the Jews greeted the Prophet, peace be upon him, and said: "As-sam 'alaykum" (death be upon you). He replied: "And upon you." Aisha, may Allah be pleased with her, became angry and said: "Did you not hear what they said?" He said: "Yes, I have [ سمعت فـ ] (2) replied to them. We respond to them, but they do not respond to us."

851/1112 (Hasan) from Uqbah ibn Amir al-Juhani: That he passed by a man whose appearance was that of a Muslim, so he greeted him with salam, and the man replied: "And upon you be peace, and the mercy of Allah, and His blessings." Then a boy said to him: "He is a Christian!" So Uqbah got up and followed him until he caught up with him. He said: "Indeed, the mercy of Allah and His blessings are upon the believers, but may Allah prolong your life, and increase your wealth and your children."(1)

852/1113 (Sahih) From Ibn Abbas who said: "If Pharaoh were to say to me: 'May Allah bless you,' I would say: 'And you as well,' and Pharaoh has died."

853/1115- From Abdur Rahman [هو ابن محمد بن زيد بن جدعان] who said: Ibn Umar passed by a Christian, so he greeted him with salam, and the Christian replied to him. Then he was informed that he was a Christian, so when he knew, he went back and said: "Return my salam to me."

I said: The hadith of Aisha mentioned earlier under number (638/827) is attributed beneath it.
