Sahih Muslim 1066d
'Abida narrated from 'Ali that he made a mention of the Khwarij (and in this connection) said that there would be a person among them with a defective hand. (or with a short hand) or a fleshy hand. If you were to exercise restraint, I would tell you what Allah has promised to those who would kill them on the order of Muhammad ﷺ. I (the narrator) said to him: Did you hear it from Muhammad ﷺ? He ('Ali) said: Yes, by the Lord of the Ka'ba; Yes, by the Lord of the Ka'ba; yes, by the Lord of the Ka'ba.
