Musnad Ahmad Hadith 4258

I was in my house in Koofah and I heard at the door of the house (the words), Peace be upon you, may I enter? I said: And upon you be peace; come in. When he came in I saw that he was 'Abdullah bin Mas'ood. I said: O Abu ‘Abdur-Rahman, what time is this for a visit? And that was in the middle of the day. He said: I could not wait until the end of the day; I thought I should talk to someone. And he started talking to me about the Messenger of Allah (ﷺ) and I talked to him. Then he started telling me: I heard the Messenger of Allah (ﷺ) say: “There will be a turmoil in which one who is sleeping will be better than one who is lying down, one who is lying down will be better than one who is sitting one who is sitting will be better than one who is standing, one who is standing will be better than one who is walking, one who is walking will be better than one who is riding, one who is riding will be better than one who is trotting (on his mount), and all its slain will be in Hell.” I said: O Messenger of Allah, when will that be? He said: “Those will be days of al-harj (killing).” I said. When will the days of al-harj be? He said: "When a man does not feel safe with the one he is sitting with.” I said: What do you instruct me to do if I live to see that? He said: “Control yourself and your hand (i.e., do not get involved) and go into your house." I said: O Messenger of Allah, what if a man enters my house? He said: “Go into your room." I said: what if he enters my room? He said: Go into your prayer place and do like this" - and he took hold of his elbow with his right hand, “and say: My Lord is Allah, until you die in that state."
