Musnad Ahmad 32:1774

Surayj ibn al-Nu‘man narrated to us, Fulayh narrated to us, from Hilal ibn ‘Ali, from Anas ibn Malik, who said: The Prophet, peace and blessings of Allah be upon him, prayed with us one day, then he ascended the pulpit and gestured with his hand toward the direction of the mosque’s qibla. Then he said: "O people, I have seen, since I prayed the prayer for you, Paradise and Hell represented before this wall. I have not seen the like of today in terms of good and evil." He said it three times.
