Musnad Ahmad 1608

It was narrated from Busr bin Sa"eed that Sa"d bin Abi Waqqas said, at the time of the turmoil surrounding "Uthman bin "Affan: "There will be turmoil in which the one who is sitting will be better than the one who is standing, 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. He said: How about if he enters upon me in my house and stretches out his hand wanting to kill me? He said: "Be like the son of Adam.”
