Shareek bin Shihab (may Allah have mercy on him) says: I had a desire to meet a companion of the Prophet (peace be upon him) who would narrate to me a hadith about the Khawarij. So, on the day of Arafah, I met Abu Barzah (may Allah be pleased with him) along with some of his companions. I said to him, "O Abu Barzah! If you heard the Prophet (peace be upon him) say anything regarding the Khawarij, please narrate that hadith to us." He said, "I will narrate to you the hadith which my ears heard and my eyes saw. Once, some dinars came to the Prophet (peace be upon him), and he was distributing them. There was a black man there whose hair was cut short, he was wearing two white garments, and there were marks of prostration between his eyes (on his forehead). He came before the Prophet (peace be upon him), but the Prophet did not give him anything. He came from the right side, but the Prophet did not give him anything. He came from the left side and from behind, but still the Prophet did not give him anything. Seeing this, he said, 'By Allah, O Muhammad (peace be upon him), today, since you have been distributing, you have not done justice.' At this, the Prophet (peace be upon him) became extremely angry and said, 'By Allah! After me, you will not find anyone more just than me.' He repeated this sentence three times. Then he said, 'Some people will emerge from the east, and perhaps he is among them, and their appearance will be like this. They will recite the Qur'an, but it will not go beyond their throats. They will leave the religion as an arrow leaves its prey; they will not return to it.' Saying this, the Prophet (peace be upon him) placed his hand on his chest. 'Their sign will be shaving the head. These people will continue to emerge in every era until the last of them appears. When you see them, kill them.' He said this three times. 'And they are the worst of creation.' He said this three times.
