Musnad Abu Ya'la al-Mawsili 6:101

Suwayd ibn Sa'id narrated to us, Mu'tamir narrated to us, from Dawud ibn Abi Hind, from Abu 'Uthman, from Sa'd ibn Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There will be a tribulation in which the one sitting is better than the one standing, and the one standing in it is better than the one walking, and the one walking is better than the one running. And the one running in it is better than the one riding, and the one riding in it is better than the one who is positioned [in the midst of it]."
