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.'
