Musnad Ahmad 788:3

'Abd al-Samad narrated to us, Hisham narrated to us, from Qatadah, from al-Hasan, from Abu Musa al-Ash'ari, who said: The Messenger of Allah (ﷺ) said: "By the One in Whose hand is the soul of Muhammad, indeed, good (al-ma'ruf) and evil (al-munkar) are two creations that will be set up for the people on the Day of Resurrection. As for the good, it will give glad tidings to its people and promise them good. As for the evil, it will say: 'Away with you, away with you!' And they will not be able to do anything but cling to it."
