Narrated `Aisha: That the Prophet said to her, "Gabriel sends Salam (greetings) to you." She replied, "Wa 'alaihi-s- Salam Wa Rahmatu-l-lah." (Peace and Allah's Mercy be on him).

Narrated `Urwa-bin Az-Zubair: Usama bin Zaid said, "The Prophet rode over a donkey with a saddle underneath which there was a thick soft Fadakiya velvet sheet. Usama bin Zaid was his companion rider, and he was going to pay a visit to Sa`d bin Ubada (who was sick) at the dwelling place of Bani Al-Harith bin Al-Khazraj, and this incident happened before the battle of Badr. The Prophet passed by a gathering in which there were Muslims and pagan idolators and Jews, and among them there was `Abdullah bin Ubai bin Salul, and there was `Abdullah bin Rawaha too. When a cloud of dust raised by the animal covered that gathering, `Abdullah bin Ubai covered his nose with his Rida (sheet) and said (to the Prophet), "Don't cover us with dust." The Prophet greeted them and then stopped, dismounted and invited them to Allah (i.e., to embrace Islam) and also recited to them the Holy Qur'an. `Abdullah bin Ubai' bin Salul said, "O man! There is nothing better than what you say, if what you say is the truth. So do not trouble us in our gatherings. Go back to your mount (or house,) and if anyone of us comes to you, tell (your tales) to him." On that `Abdullah bin Rawaha said, "(O Allah's Apostle!) Come to us and bring it(what you want to say) in our gatherings, for we love that." So the Muslims, the pagans and the Jews started quarreling till they were about to fight and clash with one another. The Prophet kept on quietening them (till they all became quiet). He then rode his animal, and proceeded till he entered upon Sa`d bin 'Ubada, he said, "O Sa`d, didn't you hear what Abu Habbab said? (He meant `Abdullah bin Ubai). He said so-and-so." Sa`d bin 'Ubada said, "O Allah's Apostle! Excuse and forgive him, for by Allah, Allah has given you what He has given you. The people of this town decided to crown him (as their chief) and make him their king. But when Allah prevented that with the Truth which He had given you, it choked him, and that was what made him behave in the way you saw him behaving." So the Prophet excused him.

And Abdullah bin Umar (may Allah be pleased with them both) said: Do not greet those who drink alcohol.

Narrated `Abdullah bin Ka`b: I heard Ka`b bin Malik narrating (when he did not join the battle of Tabuk): Allah's Apostle forbade all the Muslims to speak to us. I would come to Allah's Apostle and greet him, and I would wonder whether the Prophet did move his lips to return to my greetings or not till fifty nights passed away. The Prophet then announced (to the people) Allah's forgiveness for us (acceptance of our repentance) at the time when he had offered the Fajr (morning) prayer.

Narrated `Aisha: A group of Jews came to Allah's Apostle and said, "As-samu 'Alaika " (Death be on you), and I understood it and said to them, "Alaikum AsSamu wa-l-la'na (Death and curse be on you)." Allah's Apostle said, "Be calm! O `Aisha, for Allah loves that one should be kind and lenient in all matters." I said. "O Allah's Apostle! Haven't you heard what they have said?" Allah's Apostle said, "I have (already) said (to them), 'Alaikum (upon you).' "

Narrated `Abdullah bin `Umar: Allah's Apostle said, "When the Jews greet you, they usually say, 'As-Samu 'alaikum (Death be on you),' so you should say (in reply to them), 'Wa'alaikum (And on you).

Narrated Anas bin Malik: the Prophet said, "If the people of the Scripture greet you, then you should say (in reply), 'Wa'alaikum (And on you).' "

Narrated `Ali: Allah's Apostle sent me, Az-Zubair bin Al-Awwam and Abu Marthad Al-Ghanawi, and all of us were horsemen, and he said, "Proceed till you reach Rawdat Khakh, where there is a woman from the pagans carrying a letter sent by Hatib bin Abi Balta'a to the pagans (of Mecca)." So we overtook her while she was proceeding on her camel at the same place as Allah's Apostle told us. We said (to her) "Where is the letter which is with you?" She said, "I have no letter with me." So we made her camel kneel down and searched her mount (baggage etc) but could not find anything. My two companions said, "We do not see any letter." I said, "I know that Allah's Apostle did not tell a lie. By Allah, if you (the lady) do not bring out the letter, I will strip you of your clothes' When she noticed that I was serious, she put her hand into the knot of her waist sheet, for she was tying a sheet round herself, and brought out the letter. So we proceeded to Allah's Apostle with the letter. The Prophet said (to Habib), "What made you o what you have done, O Hatib?" Hatib replied, "I have done nothing except that I believe in Allah and His Apostle, and I have not changed or altered (my religion). But I wanted to do the favor to the people (pagans of Mecca) through which Allah might protect my family and my property, as there is none among your companions but has someone in Mecca through whom Allah protects his property (against harm). The Prophet said, "Habib has told you the truth, so do not say to him (anything) but good." `Umar bin Al-Khattab said, "Verily he has betrayed Allah, His Apostle, and the believers! Allow me to chop his neck off!" The Prophet said, "O `Umar! What do you know; perhaps Allah looked upon the Badr warriors and said, 'Do whatever you like, for I have ordained that you will be in Paradise.'" On that `Umar wept and said, "Allah and His Apostle know best."

Narrated Abu Sufyan bin Harb: that Heraclius had sent for him to come along with a group of the Quraish who were trading in Sha'm, and they came to him. Then Abu Sufyan mentioned the whole narration and said, "Heraclius asked for the letter of Allah's Apostle . When the letter was read, its contents were as follows: 'In the name of Allah, the Beneficent, the Merciful. From Muhammad, Allah's slave and His Apostle to Heraclius, the Chief of Byzantines: Peace be upon him who follows the right path (guidance)! Amma ba'du (to proceed)...' (See Hadith No 6, Vol 1 for details)

Narrated Abu Hurairah (ra): Allah's Messenger (saws) mentioned a person from Bani Israel who took a piece of wood, made a hole in it, and put therein one thousand Dinar and letter from him to his friend. The Prophet (saws) said, "(That man) cut a piece of wood and put the money inside it and wrote a letter from such and such a person to such and such a person."
