Musannaf Ibn Abi Shayba 23:208

'Affan narrated to us, he said: Hammad bin Salamah narrated to us, he said: 'Ali bin Zayd and Abu 'Imran al-Jawni informed us that Samurah bin Jundub said to Abu Bakr: "I saw in a dream as if I were twisting a rope and placing it by my side, and a group of people were eating it." He said: "You will marry a woman who has a child who will eat your earnings." He said: "And I saw a bull that came out of a hole, and it was not able to return into it." He said: "This is a grave word that comes out of a man's mouth, and he is not able to take it back." He said: "And I saw as if it were said: 'The Dajjal is emerging,' so I began to leap over the walls. Then I looked behind me, and the earth opened up for me, so I entered it." He said: "A hardship will befall you in your religion, and the Dajjal is close on your heels."
