Musannaf Ibn Abi Shaybah 40743 — Reports on the Khawarij

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) was distributing among us the spoils of Khaybar when a man from Banu Tamim, who was called Dhu al-Khuwaysirah, came and said: "O Messenger of Allah, be just." He said: "Woe to you! If I am not just, then what doubt is there of my failure and loss?" Sayyiduna Umar (may Allah be pleased with him) said: "O Messenger of Allah, permit me and I will kill him." He said: "No. He has companions who will appear at a time of disagreement among the people. They will recite the Qur'an, but the Qur'an will not go down past their throats. They will pass out of the religion just as an arrow passes through its target. You will consider your prayer insignificant beside their prayer, and you will consider your fasting insignificant beside their fasting. Their sign will be that among them there will be a man with a hand like a woman's breast, dangling like a piece of flesh." Sayyiduna Abu Sa'id (may Allah be pleased with him) said: My ears heard this on the day of Hunayn, and my eyes saw, in the company of Sayyiduna Ali (may Allah be pleased with him) in the battle against the Khawarij, that he was brought out, and I looked at this man with the sign.
