Hazrat Abu Barqa Sa’idi narrates that when Hazrat Ali (may Allah be pleased with him) killed Dhu’l-Thadiyya, Hazrat Sa’d said that Ibn Abi Talib has killed the snake of the hole.

Hazrat Abu Razin narrates that when the government was at Siffin, and the Khawarij left Hazrat Ali (may Allah be pleased with him) and departed from him. The Khawarij were in one army and Hazrat Ali (may Allah be pleased with him) was in another army. When Hazrat Ali (may Allah be pleased with him) returned to Kufa with his army and they (the Khawarij) went to Harura with their army, Hazrat Ali (may Allah be pleased with him) sent Hazrat Ibn Abbas (may Allah be pleased with them both) to them, but he found no leeway. Then Hazrat Ali (may Allah be pleased with him) himself went to talk to them, and there was a conversation, and all became reconciled with each other. And they returned to Kufa. This reconciliation lasted for two or three days. Then Ash'ath bin Qais came, who used to come to Hazrat Ali (may Allah be pleased with him) often, and he said that people are saying that you have reconciled with them despite their disbelief. The next day or on Friday, Hazrat Ali (may Allah be pleased with him) ascended the pulpit, praised Allah Almighty, and in his sermon advised them. He mentioned their separation from the people, commanded them regarding the matter in which they had separated, and Hazrat Ali (may Allah be pleased with him) condemned them and their way. When he descended from the pulpit, voices began to rise from the corners of the mosque, saying: "There is no command except that of Allah!" Hazrat Ali (may Allah be pleased with him) said: "I am waiting for Allah's command regarding you." Then, from the pulpit, he signaled them with his hand to remain silent. Meanwhile, a man from among the Khawarij came, placing his fingers in his ears, reciting this verse: { لَئِنْ أَشْرَکْتَ لَیَحْبَطَنَّ عَمَلُک وَلَتَکُونَنَّ مِنَ الْخَاسِرِینَ }.

The mention of the Khawarij was made before Hazrat Ibn Abbas (may Allah be pleased with them), and their worship and efforts were discussed. He said: "They are not more striving than the Jews and Christians, nor do they pray more than them."

It was mentioned before Hazrat Ibn Abbas (may Allah be pleased with them both) that the Khawarij always take the Qur'an as their foundation. He said: They believe in its clear (muhkam) verses and are destroyed because of its ambiguous (mutashabih) ones.

Hazrat Bishr bin Shaghaf narrates that Hazrat Abdullah bin Salam asked me about the Khawarij, so I replied that they are the ones who pray the longest prayers and fast the most. But when they cross the bridge, they shed blood and seize wealth. He said that you will be asked this same question about them. I told him not to martyr Hazrat Uthman, to leave him alone. By Allah, if you leave him for eleven nights, he will pass away on his bed. But they did not do so. When a prophet is killed, seventy thousand people are killed in retribution, and when a caliph is killed, thirty-five thousand people are killed in retribution.

Hazrat Abu Tufail narrates that during the time of the Messenger of Allah, peace and blessings be upon him, a child was born. The Prophet prayed for him and touched the skin of his forehead. The narrator says that a curved hair, like that of a horse, appeared on the boy’s forehead. Then the boy grew up, and when the era of the Khawarij came, he inclined towards the Khawarij. Then that hair fell from his forehead. His father caught him and tied him up because he feared that he might join the Khawarij. We met him once and advised him, and we said to him,“Do you not see that even the blessing of the Messenger of Allah, peace and blessings be upon him, has fallen from your forehead?”We kept advising him in this way until he abandoned his opinion. Then Allah Almighty restored the hair on his forehead, and he repented and reformed himself.

When the Khawarij were mentioned in the presence of Hazrat Abu Hurairah, he said: "They are the worst of creatures."

Hazrat Abu Bar Saidi narrates that when Hazrat Ali (may Allah be pleased with him) killed Dhu’l-Thadiyya, Hazrat Sa’d said that the son of Abu Talib has killed the snake of the hole.

Hazrat Asim bin Damrah narrates that the Khawarij raised their voices against the government and proclaimed the slogan that there is no rule except that of Allah. Hazrat Ali (may Allah be pleased with him) said regarding this: "Indeed, there is no rule except that of Allah, but these people say that there should be no leadership at all, whereas it is necessary for people to have a leader, whether he is righteous or wicked. A believer works under his leadership, a disbeliever lives under it, and Allah the Exalted brings it to its appointed term."

Hazrat Mughira narrates that Hazrat Umar bin Abdul Aziz held discussions with the Khawarij. Among them, those who wished to repent did so. One group among them refused to repent. Hazrat Umar bin Abdul Aziz sent a cavalry force towards them and instructed them to go to the place where the Khawarij were staying. He ordered that they should not be harmed or provoked; if the Khawarij killed or caused corruption in the land, then attack them and fight against them. But if they did not fight and did not cause corruption in the land, then leave them and let them do as they wish.
