Musannaf Ibn Abi Shaybah 40706 — Reports on the Khawarij

A man of Banu Abd al-Qays said: I was with the Khawarij, and I saw among them things that I disliked. So I parted from them on the condition that I would not add to their numbers. I was still with a group of them when they saw a man who had come out as if terrified, with a river between them and him. They crossed the river to seize this man and said: "Perhaps we have frightened you." He said: "Yes, something like that." They asked: "Who are you?" The man said: "I am Abdullah bin Khabbab bin al-Aratt." They said: "You have a hadith that you narrate on the authority of your father." He said: "Yes, my father narrated to me from the Messenger of Allah (peace and blessings be upon him): 'A tribulation is coming. The one sitting in it will be better than the one standing, and the one standing will be better than the one walking. When you meet them, if you can be Allah's slain servant, then be so, but do not be Allah's slaying servant.'" Then they took Abdullah bin Khabbab near the river and cut off his neck. I saw his blood flowing on the water like a sandal strap, not mixing with the water until it passed out of sight. Then they called for a pregnant slave-woman of Abdullah bin Khabbab and ripped open her belly.
