Musannaf Ibn Abi Shayba 37:24

Abdullah ibn Numayr narrated to us, from al-Walid ibn Jami’, from ‘Amir ibn Wathilah, who said: Hudhayfah said: "There will be three tribulations. The fourth will drive them toward the Dajjal; the one that throws [like] dry earth, and the one that throws [like] heated stones, and the dark one that surges like the surging of the sea."
