"I used to wish that I could meet a man among the Companions of the Prophet became very angry and said: "By Allah! You will not find a man after me who is more just than me." Then he said: "A people will come at the end of time; as if he is one of them, reciting the Qur'an without it passing beyond their throats. They will go through Islam just as the arrow goes through the target. Their distinction will be shaving. They will not cease to appear until the last of them comes with Al-Masih Ad-Dajjal. So when you meet them, then kill them, they are the worst of created beings."
Sunan an-Nasa'i Book 37, Hadith 138
← Previous Hadith "I heard the Messenger of Allah say: 'At the end of time there will appear young people with foolish minds. Their faith will not pass through their throats, and they will go out of Islam as an arrow goes through the target. If you meet them, then kill them, for killing them will bring reward to the one who killed them on the Day of Resurrection.'"
