Sayyiduna Muhammad bin Maslamah Ansari (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "O Muhammad! When you see people fighting over the world, then take your sword and strike it on a strong stone of the Haram so that it breaks, then sit in your house until either the hand of a wrongdoer reaches you, or decisive death comes to you." So I did exactly what the Messenger of Allah (peace and blessings be upon him) had commanded me.
