Musannaf Ibn Abi Shayba 24:135

Yahya ibn Adam narrated to us, he said: Fitr narrated to us, he said: Mundhir al-Thawri narrated to us, from Muhammad ibn Ali ibn al-Hanafiyyah, who said: "Beware of these tribulations (fitan), for no one looks toward them except that they overtake him. Know that these people have an appointed time and a duration. If everyone on earth were to agree to remove their dominion, they would not be able to do so until Allah is the One who permits it. Are you able to remove these mountains?"
