“I entered upon Muhammad bin Maslamah and he said that the Messenger of Allah (ﷺ) said: ‘There will be tribulation, division and dissension. When that comes, take your sword to Uhud and strike it until it breaks, then sit in your house until there comes to you the hand of the evildoer (to kill you) or a predestined (natural) death.’” "And that came to pass, and I did as the Messenger of Allah (ﷺ) said."
Sunan Ibn Majah Book 36, Hadith 37
← Previous Hadith “Before the Hour comes, there will be tribulation like pieces of black night, when a man will wake up as a believer but be a disbeliever by evening, or he will be a believer in the evening but will be a disbeliever by morning. And the one who is sitting will be better than the one who is standing, and the one who is standing will be better than the one who is walking, and the one who is walking will be better than the one who is running. So break your bows, cut their strings and strike your swords against rocks, and if anyone enters upon anyone of you, let him be like the better of the two sons of Adam. (i.e. the one killed, not the killer).”
