If you could exercise restraint, I would have told you what Allah promised on the lips of Muhammad ﷺ to those who kill them. I said: Did you hear that from Muhammad ﷺ? He said: Yes, by the Lord of the Kaʿbah; yes, by the Lord of the Kaʿbah; yes, by the Lord of the Kaʿbah. (Using translation from Aḥmad 626)
