Musannaf Ibn Abi Shayba 21:426

Yazid ibn Harun narrated to us, Ibn 'Awn informed us, from Ibrahim al-Nakha'i, who said: They used to, when one of them saw in his sleep what he disliked, say: "I seek refuge by that which the angels of Allah and His messengers sought refuge by, from the evil of what I saw in my sleep, that any of it should afflict me which I dislike in the world and the Hereafter."
