Prophet prophesied the traits of Deviants.

They will recite the Qur'an which will not exceed their throats i.e they will not understand Quran correctly.
Sahih Al-Bukhari HadithHadith 6.578 Narrated byAbu Said Al Khudri
I heard Allah's Apostle saying, "There will appear some people among you whose prayer will make you look down upon yours, and whose fasting will make you look down upon yours, but they will recite the Qur'an which will not exceed their throats (they will not act on it) and they will go out of Islam as an arrow goes out through the game whereupon the archer would examine the arrowhead but see nothing, and look at the unfeathered arrow but see nothing, and look at the arrow feathers but see nothing, and finally he suspects to find something in the lower part of the arrow."

Best speech of all people (i.e. the Qur'an)
Sahih Al-Bukhari HadithHadith 4.808 Narrated byAli
I relate the traditions of Allah's Apostle to you for I would rather fall from the sky than attribute something to him falsely. But when I tell you a thing which is between you and me, then no doubt, war is guile. I heard Allah's Apostle saying, "In the last days of this world there will appear some young foolish people who will use (in their claim) the best speech of all people (i.e. the Qur'an) and they will abandon Islam as an arrow going through the game. Their belief will not go beyond their throats (i.e. they will have practically no belief), so wherever you meet them, kill them, for he who kills them shall get a reward on the Day of Resurrection."

Shaving (of their beards)
Sahih Al-Bukhari HadithHadith 9.651 Narrated byAbu Said Al Khudri
The Prophet said, "There will emerge from the East some people who will recite the Qur'an but it will not exceed their throats and who will go out of (renounce) the religion (Islam) as an arrow passes through the game, and they will never come back to it unless the arrow, comes back to the middle of the bow (by itself) (i.e., impossible). The people asked, "What will their signs be?" He said, "Their sign will be the habit of shaving (of their beards). (Fateh Al-Bari, Page 322, Vol. 17th)

About Al-Khawarij
Sahih Al-Bukhari HadithHadith 9.68 Narrated byYusair 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 Quran 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.' "

*Note:The Kharijites:-After the Battle of Siffin the Kharijites had separated from the community and camped at Harura a few miles from Kufa.

Al-Tirmidhi HadithHadith 3553 Narrated byAbuBarzah al-Aslami
Sharik ibn Shihab said, "I wanted to meet one of the Prophet's companions to ask him about the Kharijites. Meeting AbuBarzah al-Aslami along with some of his companions on a festival day, I asked whether he had heard Allah's Messenger (peace be upon him) mentioning the Kharijites. He replied that he had heard him with both his ears and seen him with his eyes. He said that Allah's Messenger (peace be upon him) was brought some property and divided it, giving something to those on his right and those on his left, but giving nothing to those who were behind him. One of those behind him, a black man whose hair was completely cut off and who was wearing two white garments, then said, "You have not divided justly, Muhammad." Allah's Messenger (peace be upon him) became very angry and said, "I swear by Allah that after my death you will not find a man more just than I am." He added, "At the end of time people looking like this man will come forth, reciting the Qur'an, but it will not pass
their throats. They will swerve from Islam as an arrow passes through the game at which is it shot, and their distinguishing mark will be shaving. They will continue to come forth till the last of them comes forth with the antichrist. When you meet them they will be the worst of men and beasts."
Nasa'i transmitted it.

Sahih Al-Bukhari HadithHadith 9.527 Narrated byAbu Said Al Khudri
When 'Ali was in Yemen, he sent some gold in its ore to the Prophet. The Prophet distributed it among Al-Aqra' bin Habis Al-Hanzali who belonged to Bani Mujashi, 'Uyaina bin Badr Al-Fazari, 'Alqama bin 'Ulatha Al-'Amiri, who belonged to the Bani Kilab tribe and Zaid Al-Khail At-Ta'i who belonged to Bani Nabhan. So the Quraish and the Ansar became angry and said, "He gives to the chiefs of Najd and leaves us!" The Prophet said, "I just wanted to attract and unite their hearts (make them firm in Islam)." Then there came a man with sunken eyes, bulging forehead, thick beard, fat raised cheeks, and clean-shaven head, and said, "O Muhammad! Be afraid of Allah! " The Prophet said, "Who would obey Allah if I disobeyed Him? (Allah). He trusts me over the people of the earth, but you do not trust me?" A man from the people (present then), who, I think, was Khalid bin Al-Walid, asked for permission to kill him, but the Prophet prevented him. When the man went away, the Prophet said, "Out of
the offspring of this man, there will be people who will recite the Qur'an but it will not go beyond their throats, and they will go out of Islam as an arrow goes out through the game, and they will kill the Muslims and leave the idolators. Should I live till they appear, I would kill them as the Killing of the nation of 'Ad."

3:161 No prophet could (ever) be false to his trust. If any person is so false He shall on the Day of Judgment restore what he misappropriated; then shall every soul receive its due whatever it earned and none shall be dealt with unjustly.

There will be good muslims who will fight with them they will remain on earth & fight with muslims along with Dajjal[anti-christ]
sunan of Abu-DawoodHadith 2478 Narrated byImran ibn Husayn
The Prophet (peace be upon him) said: A section of my community will continue to fight for the right and overcome their opponents till the last of them fights with the Antichrist.

They will be in conflict with each other.
Sahih Al-Bukhari HadithHadith 1.467 Narrated byIbn Umar or Ibn Amr
The Prophet clasped his hands, by interlacing his fingers. Narrated 'Abdullah that Allah's Apostle said, "O 'Abdullah bin 'Amr! What will be your condition when you will be left with the sediments of (worst) people?" (They will be in conflict with each other).

In the last days (of the world) & Young people with foolish thoughts and ideas:
Sahih Al-Bukhari HadithHadith 6.577 Narrated byAli
I heard the Prophet saying, "In the last days (of the world) there will appear young people with foolish thoughts and ideas. They will give good talks, but they will go out of Islam as an arrow goes out of its game, their faith will not exceed their throats. So, wherever you find them, kill them, for there will be a reward for their killers on the Day of Resurrection."

They follow thereof that is not entirely clear seeking affliction and searching for its hidden meanings
Sahih Al-Bukhari HadithHadith 6.70 Narrated byAisha
Allah's Apostle recited the Verse:
"It is He who has sent down to you the Book. In it are Verses that are entirely clear, they are the foundation of the Book, others not entirely clear. So as for those in whose hearts there is a deviation (from the Truth ), follow thereof that is not entirely clear seeking affliction and searching for its hidden meanings; but no one knows its hidden meanings but Allah. And those who are firmly grounded in knowledge say: "We believe in it (i.e. in the Qur'an) the whole of it (i.e. its clear and unclear Verses) are from our Lord. And none receive admonition except men of understanding." (3.7)
Then Allah's Apostle said, "If you see those who follow thereof that is not entirely clear, then they are those whom Allah has named [as having deviation (from the Truth). So beware of them."

The hand of Allah is upon the community:
Al-Tirmidhi HadithHadith 173 Narrated byAbdullah ibn Umar
Allah's Messenger (peace be upon him) said: Verily my Ummah, or the Ummah of Muhammad, will not agree on error and the hand of Allah is upon the community; he who sets himself apart from it will be set apart in Hell Fire.

Sunan of Abu-DawoodHadith 4740 Narrated byAbuDharr
The Prophet (peace be upon him) said: He who separates from the community within a span takes off the noose of Islam from his neck.

Its very important to learn evil in order to avoid it .
The hadith rejectors are the fitna of today.

Their ancestors were Khawarij or Kharijites ("dissenters") .They were the first sect to split away from mainstream Islam. These are the extensions of khawarijites with slight changes and additions and manupulations added or substracted in their doctrines to distort Islam.Khawarij ideas and beliefs themselves have not ceased to exist. Rather, their followers and those affected by them are present in our very midst.
A conscise look at the reason & belief system of the first sect to split away.
Ash-Shahrastaanee defines them as: ((Anyone who walks out against (seeking to overthrow) the true appointed Imaam (leader) upon whose leadership the Jamaa'ah is in agreement is called a Khaarijee. This is the case, despite whether the walking out (against the Imaam) occurred in the days of the Rightly-Guided Khulafaa. or other than them from the Taabi'een)).

It should be known that the view Kharijites, with which none of the mainstreams Muslims agreed, implied that the people who committed major sins would abide forever in Hell.
This claim was one of the important innovations because the Companions and Successors of the Prophet (pbuh), their followers, and all religious Muslims agreed that whoever has an atom's weight of Iman in his heart will not abide forever in Hell.
Extreme Kharijites considered moderate Muslims to be 'hypocrites' or 'unbelievers', who could be killed with impunity; this practice is called takfir.They rejected capital punishments,they said no one should judge etc.

Kharijiyyah emerged in the first century of Islam . During the reign of the third caliph, 'Uthman,r.a certain groups accused the khalifah of nepotism and misrule, & this discontent led to his assassination in 656. After 'Uthman's [r.a] death[martyrdom] Ali[r.a], the cousin of the Prophet, was invited by the Muslims at Madina to accept the khilafath, which he did, and thus became the fourth khalifah (656-661). Ali's rule was opposed by Uthman's nephew, Mu'awiyah[r.a], who rebelled against Ali[r.a], but subsequently agreed to settle the issue of who should lead the community through human arbitration. The principle of the use of human arbitration for this purpose was opposed by certain groups within the community, who became known to history as the Kharijites (a term which means "those who go out, go off").
Because of their belief that the pursuit of truth was done through the use of the sword, they embarked upon endless campaigns against the community. Gradually they were subdued, and within two centuries of Islam were wiped out. But all of them did not die.Later they came to makkah and stayed there under the khlilafah of Ali[r.a].
