Musnad Abu Ya'la al-Mawsili 210:12

Harun ibn Abdullah al-Bazzaz narrated to us, Sufyan narrated to us, from Umayyah ibn Safwan, who heard his grandfather say: Hafsa narrated to me that he [the Prophet] said: "An army will intend [to attack] this House, invading it, until when they are in a desert land, their middle [ranks] will be swallowed up. Then their first [ranks] will call out to their last, and they will all be swallowed up, and none will be saved except the one who flees to tell about them." Sufyan said: A man stood up to Umayyah and said: "I bear witness against you that you did not lie about your grandfather, and I bear witness against your grandfather that he did not lie about Hafsa, and I bear witness against Hafsa that she did not lie about the Messenger of Allah, may Allah bless him and grant him peace."
