Narrated Anas bin Malik: A Jew passed by Allah's Apostle and said, "As-Samu 'Alaika." Allah's Apostle said in reply, "We 'Alaika." Allah's Apostle then said to his companions, "Do you know what he (the Jew) has said? He said, 'As-Samu 'Alaika.'" They said, "O Allah's Apostle! Shall we kill him?" The Prophet, said, "No. When the people of the Book greet you, say: 'Wa 'Alaikum.'"

Narrated `Aisha: A group of Jews asked permission to visit the Prophet (and when they were admitted) they said, "As- Samu 'Alaika (Death be upon you)." I said (to them), "But death and the curse of Allah be upon you!" The Prophet said, "O `Aisha! Allah is kind and lenient and likes that one should be kind and lenient in all matters." I said, "Haven't you heard what they said?" He said, "I said (to them), 'Wa 'Alaikum (and upon you).

Narrated Ibn `Umar: Allah's Apostle 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 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."

Allah, the Exalted, has said «وما كان الله ليضل قوما بعد إذ هداهم حتى يبين لهم ما يتقون‏» : "Allah does not punish a people after He has guided them (i.e., granted them the ability to believe) until He makes clear to them what they should avoid." And Abdullah ibn Umar (may Allah be pleased with them both) (as connected by Tabari) considered the Khawarij to be the worst of Allah's creation. He used to say: "What have they done? The verses that were revealed regarding the disbelievers, they have applied them to the Muslims."

Narrated `Ali: Whenever I tell you a narration from Allah's Apostle, by Allah, I would rather fall down from the sky than ascribe a false statement to him, but if I tell you something between me and you (not a Hadith) then it was indeed a trick (i.e., I may say things just to cheat my enemy). No doubt I heard Allah's Apostle saying, "During the last days there will appear some young foolish people who will say the best words but their faith will not go beyond their throats (i.e. they will have no faith) and will go out from (leave) their religion as an arrow goes out of the game. So, where-ever you find them, kill them, for who-ever kills them shall have reward on the Day of Resurrection."

Narrated `Abdullah bin `Amr bin Yasar: That they visited Abu Sa`id Al-Khudri and asked him about Al-Harauriyya, a special unorthodox religious sect, "Did you hear the Prophet saying anything about them?" Abu Sa`id said, "I do not know what Al-Harauriyya is, but I heard the Prophet saying, "There will appear in this nation---- he did not say: From this nation ---- a group of people so pious apparently that you will consider your prayers inferior to their prayers, but they will recite the Qur'an, the teachings of which will not go beyond their throats and will go out of their religion as an arrow darts through the game, whereupon the archer may look at his arrow, its Nasl at its Risaf and its Fuqa to see whether it is blood-stained or not (i.e. they will have not even a trace of Islam in them).

Narrated `Abdullah bin `Umar: Regarding Al-Harauriyya: The Prophet said, "They will go out of Islam as an arrow darts out of the game's body.'

Narrated Abu Sa`id: While the Prophet was distributing (something, `Abdullah bin Dhil Khawaisira at-Tamimi came and said, "Be just, O Allah's Apostle!" The Prophet said, "Woe to you! Who would be just if I were not?" `Umar bin Al-Khattab said, "Allow me to cut off his neck! " The Prophet said, " Leave him, for he has companions, and if you compare your prayers with their prayers and your fasting with theirs, you will look down upon your prayers and fasting, in comparison to theirs. Yet they will go out of the religion as an arrow darts through the game's body in which case, if the Qudhadh of the arrow is examined, nothing will be found on it, and when its Nasl is examined, nothing will be found on it; and then its Nadiyi is examined, nothing will be found on it. The arrow has been too fast to be smeared by dung and blood. The sign by which these people will be recognized will be a man whose one hand (or breast) will be like the breast of a woman (or like a moving piece of flesh). These people will appear when there will be differences among the people (Muslims)." Abu Sa`id added: I testify that I heard this from the Prophet and also testify that `Ali killed those people while I was with him. The man with the description given by the Prophet was brought to `Ali. The following Verses were revealed in connection with that very person (i.e., `Abdullah bin Dhil-Khawaisira at-Tarnimi): 'And among them are men who accuse you (O Muhammad) in the matter of (the distribution of) the alms.' (9.58)

Narrated Yusair bin `Amr: I asked Sahl bin Hunaif, "Did you hear the Prophet saying anything about Al-Khawarij?" He said, "I heard him saying while pointing his hand towards Iraq. "There will appear in it (i.e, Iraq) some people who will recite the Qur'an but it will not go beyond their throats, and they will go out from (leave) Islam as an arrow darts through the game's body.' "
